Core Expertise
High-throughput services for payment and commerce platforms.
I design event-driven backend systems with Go, .NET Core, Kafka, Redis, Kubernetes, and relational data models where reliability and auditability matter.

AI-Assisted Development
Using AI as a force multiplier, not a replacement.
The mobile apps here were built using GitHub Copilot, Claude, and Gemini alongside manual engineering. Architecture decisions, quality standards, and code ownership remain mine — AI accelerates execution without replacing judgment.
01GitHub Copilot — inline completions and refactors
02Claude — architecture, debugging, review
03Gemini — rapid prototyping and exploration
04Human judgment — always the final call
