I build backend systems that can’t afford to fail - the kind that work at 2 AM when no one’s watching. 7+ years in fintech and crypto infrastructure. Co-founded Scalex as CTO - built crypto on-ramps serving global partners across 15+ countries.
Now architecting Peniremit’s payment backbone (3-5k daily transactions in week one, near-zero support tickets). I’ve shipped cross-language packages (NPM & PyPI), migrated systems to gRPC, and I think about failure modes before they happen.
Peniremit
Remote
Architected core payment infrastructure from scratch - 7 microservices handling wallet operations, payments, notifications, file uploads, and scheduling.
Achieved 3-5k daily transactions in week one with near-zero support tickets - built resilient systems with rich admin dashboards enabling self-service issue resolution Published Shared Peniremit Utils (NPM & PyPI) standardizing proto definitions and gRPC certificate management, enabling seamless Node.js/Python interoperability across 5+ services Reduced inter-service latency by ~40% by migrating REST → gRPC with certificate-based authentication Improved system reliability by consolidating fragmented async processing (BullMQ + Redis Streams) into production-grade RabbitMQ architecture - reduced message failures by 90% Cut time-series query latency by 60% on ledger operations by migrating Virtual Wallet Service to TimescaleDB Built high-performance Upload Service in Go with pre-signed S3 URLs - zero credential exposure, handles ~3k+ uploads/day across SMC DAO (parent company) services Tech: Node.js, TypeScript, Fastify, FastAPI, gRPC, Protocol Buffers, RabbitMQ, PostgreSQL, TimescaleDB, Go, AWS S3, Docker

Bachelor of Science
Smart database seeding library
Published @seedwise/core and @seedwise/knex - tracks which seeds have run (like migrations) so they don’t re-execute - Solves duplicate seed data problem in development environments
