Open to engineering roles & consulting

Arsene ThierryKomezudufashe

Software engineer & CTO. I build and run full-stack products, REST APIs & integrations, Docker & CI/CD deployments, secure authentication, production infrastructure

I work hands-on across the stack — Next.js, Express and NestJS applications, REST APIs and third-party integrations, relational and document databases — and I own the path to production: Docker, VPS infrastructure, CI/CD, authentication and access control, monitoring, and backup and recovery.

Selected work

Products I build and run

As CTO I hold the technical decisions and still do the engineering: writing features, designing data, shipping deployments, and fixing production when it breaks.
