Full-stack software engineer, open to remote roles.
3+ years building real-time fintech and blockchain trading products on a remote team. I own features end to end, from PostgreSQL data models and NestJS / Go services to React / Next.js front ends, with a focus on correctness where money moves.
Primary front-end engineer: delivered the product redesign end to end (React, Go REST APIs, PostgreSQL migrations); authored the React 19 + Vite SSR front-end foundation and a component library used by three products.
Designed and documented (in an architecture decision record) at-most-once execution for external trade signals, so each signal trades once across regions, retries and restarts; rolled it out from shadow mode to live.
Extended the multi-region Go trade-execution engine with tiered, millisecond-precise automated exits, keeping every position sold exactly once.
Built real-time trade alerts (transactional outbox + server-sent events, integration-tested for rollback, deduplication and replay) and OAuth 2.0 PKCE sign-in with per-product access control.
Fixed trade-execution bugs from on-chain evidence; 1:1 Go test-to-code ratio, including PostgreSQL integration tests.
Built a referral and rewards program end to end: NestJS API, Prisma schema and migrations, an event-driven reward-tracking service on NATS JetStream with tests, and the Next.js pages.
Built real-time price alerts across the chart UI, NestJS API and WebSocket gateway; added portfolio and platform-volume analytics on ClickHouse.
Bitcoin NFT toolspart-time, sole developer · Jun 2023 — Feb 2025
Built and ran a NestJS NFT sales tracker (4 marketplaces, posts to X and Discord) and a Koa + Prisma API.
Dawiitech (client, in pilot testing): a pharmacy and prescription platform, with a NestJS + Prisma REST API and an Expo / React Native app with patient and pharmacy flows and push notifications; Turborepo, CI/CD, EAS builds.
Sinto Agency (fixed-term contract, Dec 2023 — Jul 2024): built, deployed and maintained 7 client websites.
devca.io (Germany, 2024): built the DevCaProxy front end from Figma designs (Next.js, Tailwind CSS).
