What I'm looking for

Seeking a remote role as Software Architect or senior Backend Engineer at a startup. Strong in system design and cloud infra. I own problems end-to-end — from architecture and DevOps to hiring — and work well with autonomy.

I'm a software engineer and technical leader with 7+ years of experience building backend systems, cloud infrastructure, and distributed architectures. Most recently, I co-founded a US-based startup where I've served as CTO — owning everything from system design and development to DevOps, IoT integrations, and hiring. I work across the full stack but my core is backend: Java, Spring Boot, Python, FastAPI, PostgreSQL, Redis, AWS, and Docker, among others.

I'm at my best in early-stage or fast-moving environments where the technical challenges are real and architecture decisions still matter. I'm comfortable leading small teams, making decisions, and keeping a clear focus on delivery and business goals.
