🔹 Architecture & System Design: Designing resilient microservices and high-load systems.
🔹 Cloud & Infrastructure: Expert knowledge of GCP, K8s orchestration, and CI/CD automation.
🔹 Modern Stack: Advanced proficiency in Go and Python, with a strong foundation in PHP.
🔹 Applied AI: Implementing AI-driven features to optimize product performance.
🔹 Technical Leadership: Guiding technical decision-making, code reviews, and mentoring.
I am driven by creating clean, efficient code and aligning technical strategy with business growth.
