About
Software Engineer with over 10 years of experience building production systems across FinTech, crypto, government, and health-tech domains. Lately I've been leaning into AI-augmented development — using tools like Claude, Claude Code, and GitHub Copilot as part of my daily workflow, and going deeper into AI engineering through hands-on coursework and project work.
My strengths
- Strong backend foundation in Python (Django, FastAPI), AWS, and Docker — language-agnostic in practice, with additional experience in Java, JavaScript, and other stacks as needed
- Hands-on experience delivering customer-facing web applications and REST APIs end to end
- Full ownership of features — from system architecture and payment integrations to frontend delivery, security remediation, and cross-functional collaboration with Product, Security, and DevOps teams
- Growing focus on AI engineering — from AI-assisted development to spec-driven workflows
- Fast learner who adapts quickly to new tech stacks and tooling as project needs evolve
