What I actually do

I build cloud infrastructure and backend systems that the integrations actually depend on.

Cloud & Integration

I design integration solutions with Dell Boomi and create, maintain and refactor cloud infrastructure with Terraform — across Google Cloud and Azure.

Backend & APIs

I design REST APIs and build both microservices and monolithic applications in Java Spring Boot. Earlier I shipped PHP/Laravel backends, databases, and Vue.js / Laravel Blade frontends.

Leadership & Architecture

Proven team management and project execution — from architecture design and database design through to code review, co-leading features end to end.

// personal interests

I'm deep into LLMs and prompt engineering, and I experiment with AI-agent tools — Cline, Codex, Claude Code — to improve work quality and cut development time, always within defined security and architectural best practices.
