I enjoy taking complicated, very real constraints and turning them into software people can rely on. I'm a Senior Software Engineer at Nubank, with 5+ years of experience across fintech, e-commerce, telecom, compliance, and enterprise products.
I work across the stack, but frontend engineering is where I started: thoughtful interfaces, fast experiences, and accessibility that holds up beyond the happy path. These days, I also spend a lot of time on integrations, data pipelines, automation, and the backend systems behind the screen.
My favorite kind of engineering: solve the actual problem, make the result easy to operate, and leave the next person a map.
The things I care about: architecture that fits the problem · performance you can measure · tests that protect behavior · security by default · documentation people can actually use.
A price-tracking platform for Amazon, Mercado Livre, and Shopee. The interesting part is the plumbing: resilient collection, idempotent ingestion, and real price history that helps separate a real deal from a fake discount. Next.js · TypeScript · Node.js · MySQL · Redis · BullMQ |
A live brewery ranking on Android TV boxes. It has to keep going through flaky networks and daily point-of-sale restarts, with a separate sync agent, API, and TV player each doing one job. Angular PWA · Flask · PostgreSQL · Python · incremental sync |
Scheduled price tracking, reports, webhooks, and notifications. A practical Node.js service built around dependable jobs and logs that make failures easier to understand. Node.js · MySQL · node-cron · Winston · Docker |
A small product of its own: multilingual, prerendered, installable, and built with the same care for performance, accessibility, and maintainability that I bring to client and product work. React · Vite · i18next · Vitest · Playwright · Docker |

I like sharing the decisions behind the code, including what didn't work and how I measured the result:
- Building an AI agent to triage security alerts — test cases, hallucination checks, and the complete prompt.
- Optimizing React apps for Core Web Vitals — practical performance work.
- Accessible React beyond ARIA — accessibility as part of product engineering.
