Senior Full Stack Engineer

Took ownership of the Invoices feature with nothing already built on the server side, built the entire backend from scratch over ~12 months, driving 87% enterprise client adoption (1,198 of 1,709 active sites) and cutting support tickets by 87% (avg. 10/month → 3/month after launch).
Inherited full ownership of the platform's translation and localisation across 4 languages (English, French, Spanish, and UK English) with no handoff and no documentation when the previous owner left, delivered consistently every sprint for 3.5 years. Eventually automated the entire process so that new translations deploy to the product without any manual steps.
Turned a forgotten, unused monitoring tool, no dashboards, no visibility into what was happening in production, no culture around it, into a company-wide standard. Built the first production dashboards across every major system owned; teams across the organisation independently adopted the practice as a delivery default.
Sole maintainer and architect of the Instance Manager, the internal system responsible for onboarding every enterprise client, where a failure means no new clients can be set up. When the original author left the company, became one of two engineers keeping it running, and later designed the complete modernisation plan, reviewed and approved by technical leadership.
Was the first on the team to work in Claude Code and drove adoption across it for code comprehension, architecture review and test coverage on a large legacy surface, which was mostly a matter of getting experienced engineers to change how they work. Outside of that, designed and shipped a production multi-agent LLM system: agent hand-off, tool design, human-in-the-loop review on anything with consequences, and evaluation and guardrails for agents acting on real client data.
One of 3 engineers who built the Security Alerts system end-to-end over 6 months, the feature that automatically detects safety incidents affecting corporate travellers worldwide and notifies them in real time via email and push notification. The only engineer to add production monitoring, giving the company its first real-time view of global traveller safety events, used by 260+ people across 200+ enterprise clients.
Built the integration connecting WhereTo to clients' enterprise finance accounts via Microsoft Dynamics 365, giving corporate travel managers real-time visibility into their account statements directly inside the platform, one of the largest single feature deliveries in the product's history, shipped with full multi-country and multi-currency support.
Noticed that enterprise clients were asking about accessibility in procurement evaluations and the product had no answer. Initiated and led the first accessibility programme in the platform's history, designing a 3-phase plan and delivering the foundation that all future accessibility work builds on.
One of the earliest advocates for AI-assisted engineering tools on the team, applied AI to automate time-consuming tasks and shared findings with colleagues until the whole team adopted similar workflows, with teammates publicly crediting the shift in team retrospectives.

Assumiu a funcionalidade de Faturas (Invoices) sem nada construído no lado do servidor, construiu todo o backend do zero em ~12 meses, levando a 87% de adoção pelos clientes corporativos (1.198 de 1.709 sites ativos) e reduzindo os tickets de suporte em 87% (média de 10/mês → 3/mês depois do lançamento).
Herdou a responsabilidade total pela tradução e localização da plataforma em 4 idiomas (inglês, francês, espanhol e inglês britânico), sem passagem de bastão nem documentação quando o responsável anterior saiu, e entregou em todos os sprints durante 3,5 anos. Depois automatizou o processo inteiro, e hoje as traduções novas chegam ao produto sem nenhum passo manual.
Transformou uma ferramenta de monitoramento esquecida e sem uso, sem dashboards, sem visibilidade do que acontecia em produção e sem cultura em torno dela, em um padrão da empresa inteira. Construiu os primeiros dashboards de produção em todos os principais sistemas do time; equipes de toda a organização adotaram a prática por conta própria como padrão de entrega.
Único mantenedor e arquiteto do Instance Manager, o sistema interno responsável pela entrada de todo cliente corporativo, onde uma falha significa que nenhum cliente novo pode ser configurado. Quando o autor original saiu da empresa, passou a ser um dos dois engenheiros que o mantinham funcionando e, mais tarde, desenhou o plano completo de modernização, revisado e aprovado pela liderança técnica.
Foi o primeiro do time a trabalhar com o Claude Code e liderou a adoção para compreensão de código, revisão de arquitetura e cobertura de testes numa grande base legada, o que foi sobretudo questão de convencer engenheiros experientes a mudar a forma de trabalhar. Fora disso, desenhou e colocou em produção um sistema multiagente com LLMs: passagem de tarefas entre agentes, desenho de ferramentas, revisão humana em tudo que tem consequência, e avaliação e salvaguardas para agentes que agem sobre dados reais de clientes.
Um dos 3 engenheiros que construíram o sistema Security Alerts de ponta a ponta em 6 meses, a funcionalidade que detecta automaticamente incidentes de segurança que afetam viajantes corporativos no mundo todo e os avisa em tempo real por e-mail e notificação push. O único engenheiro a adicionar monitoramento em produção, dando à empresa sua primeira visão em tempo real de incidentes de segurança com viajantes no mundo, usada por 260+ pessoas em 200+ clientes corporativos.
Construiu a integração que conecta o WhereTo às contas financeiras corporativas dos clientes via Microsoft Dynamics 365, dando aos gestores de viagens corporativas visibilidade em tempo real dos extratos da conta dentro da própria plataforma. Foi uma das maiores entregas de uma única funcionalidade na história do produto, com suporte completo a vários países e várias moedas.
Percebeu que clientes corporativos perguntavam sobre acessibilidade nas avaliações de compra e o produto não tinha resposta. Criou e liderou o primeiro programa de acessibilidade da história da plataforma, desenhando um plano em 3 fases e entregando a fundação sobre a qual todo o trabalho de acessibilidade seguinte se apoia.
Um dos primeiros defensores de ferramentas de engenharia assistidas por IA no time: usou IA para automatizar tarefas demoradas e compartilhou os resultados com os colegas até o time inteiro adotar fluxos parecidos, com colegas creditando publicamente a mudança nas retrospectivas.

Prise en charge de la fonctionnalité Invoices (factures) sans rien de construit côté serveur et construction de tout le backend de zéro en ~12 mois : 87 % d'adoption par les clients entreprise (1 198 sur 1 709 sites actifs) et 87 % de tickets de support en moins (moy. 10/mois → 3/mois après le lancement).
Reprise de l'entière responsabilité de la traduction et de la localisation de la plateforme en 4 langues (anglais, français, espagnol et anglais britannique), sans passation ni documentation au départ du responsable précédent, avec une livraison à chaque sprint pendant 3,5 ans, puis automatisation de tout le processus : les nouvelles traductions arrivent dans le produit sans aucune étape manuelle.
Transformation d'un outil de supervision oublié et inutilisé, sans tableaux de bord, sans visibilité sur la production et sans culture autour, en standard à l'échelle de l'entreprise. Création des premiers tableaux de bord de production sur chaque système majeur de l'équipe ; adoption spontanée de la pratique par les équipes de toute l'organisation comme standard de livraison.
Seul mainteneur et architecte de l'Instance Manager, le système interne qui assure l'intégration de chaque client entreprise, où une panne signifie qu'aucun nouveau client ne peut être configuré. Après le départ de l'auteur d'origine, l'un des deux ingénieurs qui le faisaient tourner, puis concepteur du plan complet de modernisation, revu et approuvé par la direction technique.
Premier de l'équipe à travailler avec Claude Code et moteur de son adoption pour la compréhension du code, la revue d'architecture et la couverture de tests sur un vaste code hérité, ce qui revenait surtout à convaincre des ingénieurs expérimentés de changer leur façon de travailler. En parallèle, conception et mise en production d'un système multi-agents à base de LLM : passage de relais entre agents, conception des outils, validation humaine pour tout ce qui a des conséquences, évaluation et garde-fous pour des agents qui agissent sur de vraies données clients.
L'un des 3 ingénieurs ayant construit le système Security Alerts de bout en bout en 6 mois, la fonctionnalité qui détecte automatiquement les incidents de sécurité touchant des voyageurs d'affaires dans le monde entier et les prévient en temps réel par e-mail et notification push. Le seul ingénieur à ajouter la supervision en production, donnant à l'entreprise sa première vue en temps réel des incidents de sécurité des voyageurs dans le monde, utilisée par plus de 260 personnes chez plus de 200 clients entreprise.
Construction de l'intégration qui relie WhereTo aux comptes financiers entreprise des clients via Microsoft Dynamics 365, avec, pour les gestionnaires de voyages d'affaires, une visibilité en temps réel sur leurs relevés de compte directement dans la plateforme : l'une des plus grosses livraisons d'une seule fonctionnalité de l'histoire du produit, avec une prise en charge complète de plusieurs pays et devises.
Lancement et direction du premier programme d'accessibilité de l'histoire de la plateforme, après avoir constaté que les clients entreprise posaient des questions sur l'accessibilité lors des évaluations d'achat, sans que le produit ait de réponse : plan en 3 phases et fondation sur laquelle repose tout le travail d'accessibilité qui a suivi.
L'un des premiers défenseurs des outils d'ingénierie assistés par l'IA dans l'équipe : utilisation de l'IA pour automatiser des tâches chronophages et partage des résultats avec les collègues jusqu'à l'adoption de méthodes semblables par toute l'équipe, un changement salué publiquement par les coéquipiers lors des rétrospectives.

🏆 Major Accomplishments

Inherited the Invoices feature with no backend in place and built it end-to-end over ~12 months. The result: 87% of active enterprise clients adopted the feature (1,198 of 1,709 sites), and the volume of invoice-related support requests dropped by 87%, from an average of 10 complaints per month down to 3.
Joined a company with a monitoring tool already installed but completely unused, no dashboards, no visibility into production systems, no culture around it. Built the first monitoring dashboards from scratch, applied them to every system owned, and kept advocating until teams across the engineering organisation adopted the practice independently. What started as one person's initiative became a company-wide engineering standard.
When the original author of the Instance Manager left the company, became one of only two engineers responsible for keeping it running, the internal system that onboards every new enterprise client, with no backup if it breaks. Designed the complete plan to modernise it entirely alone: documented every risk, designed every component, estimated the full scope, and had it reviewed and approved by technical leadership. The migration is now underway.

🏆 Major Accomplishments

Developed the first Brazilian government document production line in the cloud, Angular SPA consuming a microservices backend.
Designed and built eCNH alone in 2016, the first working version of Brazil's digital driver's license: an Android app showing the license with a signed QR code, and an officers' app that verifies it offline. VALID presented it to the federal government in Brasília; SERPRO, the federal data service, took over the design and built the national system, now carried by 40M+ Brazilians.
Designed the QR code security element on every new Brazilian driver's license since 2017: tested QR versions until one fit on the card, recovered well from damage and still carried a low-resolution copy of the driver's photo, which defeats photo-swap forgery.

eCNH, Brazil's Digital Driver's License

Built alone, in 2016. At VALID I designed and built the first working version of Brazil's digital driver's license by myself: an Android app that shows the license with a signed QR code, and an app for traffic officers that reads that code, printed on the card or shown on the phone, and checks its signature with no connection at all. VALID presented it to the federal government in Brasília.

The QR code was my design too. Over many meetings we tested QR versions of different sizes until we found one that fit on the card, recovered well from damage, and could still carry a low-resolution copy of the driver's photo inside the code, which defeats one of the most common forgeries, a swapped picture.

The signing keys for a national document have to sit in a hardware security module held by a public body, so the project went to SERPRO, the federal data processing service, which took over the design and built the production system. Since May 2017 every new license carries the QR code, with the license data and the driver's photo, and the digital license app was approved that July. Today more than 40 million Brazilians carry that app, CNH do Brasil, on their phones, and it started as the version I built with my own hands.

Ten years later I solved the officer's side of that problem again, in the open, on the standard that now exists for it: qredential.

Verifies a digital credential carried in a QR code with no network connection. Selective disclosure and key binding per RFC 9901, revocation checked from a cached list, in TypeScript on WebCrypto alone.

It comes straight from the eCNH above. The hardest part of that project was never the app, it was the roadside: an officer scanning a licence with one bar of signal, needing a yes or no in under a second. The libraries for this are enterprise SDKs, heavy and tied to one country's profile. This is the version a product engineer adds on a Tuesday.

Documented in nine languages, conforming to WCAG 2.2 AA, with a playground that runs the library in your browser and fires ten real attacks at the verifier so you can check its claims instead of trusting them.
