About Me

7+ Years Building
Enterprise Software

I'm a Senior Full Stack Engineer, Tech Lead, and Software Consultant with over 7 years of hands-on experience delivering production systems across enterprise SaaS, fintech, e-commerce, and cloud infrastructure.

My work spans the full stack — from architecting distributed microservices and financial compliance backends to building polished frontends and deploying production observability infrastructure. I've led cross-functional teams, mentored engineers, and worked directly with stakeholders to turn complex requirements into reliable, scalable software.

Across 200+ freelance and client projects, I've consistently delivered clean architecture and measurable results. Currently deepening my cloud expertise toward the AWS Solutions Architect Associate certification.

I work with clients across North America, Europe, and the Middle East — fully remote and on-site. Whether you need a dedicated engineer, a technical consultant, or a team lead, I deliver production-ready results across time zones.
