What I'm looking for

I seek backend-focused roles where I can build scalable APIs, integrate AI/LLMs, mentor teams, and drive delivery in agile, cloud-native environments.

I am a results-driven backend software engineer with over five years of experience building scalable, high-performance systems using Node.js, TypeScript, PHP, and microservices architecture.

I have a proven track record designing RESTful APIs, executing backend migrations, optimizing databases, and integrating third-party services, while delivering measurable improvements such as a 30% API response-time gain and 20% database performance increase.

I also design AI-enhanced backend features using LLMs and GPT APIs, mentor junior engineers, drive agile delivery, and focus on modular system design, automation, and business-impactful solutions.
