Professional summary

TypeScript across the whole stack, currently pointed at fintech. At Lannis I work on the part of the product where a wrong number is a real problem for someone: tax settlement, invoicing and the pipelines that feed them. I like owning a feature from the data model and the PRD through to the tests, not just the part that renders.

My journey

Games are what got me into code in the first place: Lua addons for Garry's Mod and Java plugins for Minecraft, long before any of it was a job. I started at Edison in 2023 with basic programming knowledge and grew into a key contributor, moving their internal systems from no-code platforms to full-code applications: landings, a marketplace, a checkout with Stripe, MercadoPago and dLocal, and the first internal API on NestJS and AWS. Since mid-2025 I've been at Lannis, working on fintech: a monthly tax settlement engine, electronic invoicing against ARCA's official web services, POS integrations and queue-backed data pipelines. Along the way my focus shifted from writing features to owning them end to end — data modeling, PRDs, technical planning and the tests that keep it all honest. I still build for gaming communities on the side, which is where I get to try things the day job would not risk.
