What I'm looking for

I'm looking for a team that values strong engineering practices — code review, thoughtful architecture, and quality testing — where I can own full stack features end-to-end and contribute to reliable production systems. I work primarily in PHP/Laravel and modern JavaScript/TypeScript, and I incorporate AI tooling (Claude Code, MCP) into my workflow when it helps me deliver faster.

I’m a full stack developer with 13+ years of experience across fintech, e-commerce, and EdTech. I specialize in PHP/Laravel, with a strong focus on architectural decision-making and rigorous code review.

In my most recent roles, I’ve built and improved full stack products using Node, TypeScript, React, and SQL-driven systems. I also leverage AI-assisted development with Claude Code and integrate MCP (Model Context Protocol) servers to speed up implementation, testing, and refactoring without sacrificing quality.

Previously, I planned and executed core solutions for a crypto fintech platform, including credit card payment processing, settlement resolution, and risk evaluation for automatic decision-making. I also delivered KYC (Know Your User) with complex data analysis for automated decisions, plus deposit resolution automation from bank data outputs and APIs, supported by PHPUnit testing strategy and code documentation.

I’ve also led development as a co-owner in a small team—driving code review, database administration, R&D, recruiting, and product planning. From SaaS integrations to Docker/Nginx-based multi-environment setups, I bring a hands-on engineering mindset, DevOps awareness, and a pragmatic approach to shipping reliable features.
