Building scalable backend systems, AI-powered applications, reliable APIs, and intelligent automation.

I’m a Software Engineer specializing in backend engineering, API development, AI integration, system integration, and automation.

I build software with a focus on scalability, maintainability, reliability, and production readiness. My work spans backend services, AI-powered applications, full-stack platforms, database-driven systems, web scraping, third-party integrations, and workflow automation.

I also enjoy integrating LLMs and AI services into real-world applications — connecting AI capabilities with APIs, business logic, databases, automation workflows, and existing software systems.

I primarily work with Python, Django, FastAPI, PHP, Laravel, Symfony, PostgreSQL, Redis, Docker, and Linux, along with modern frontend technologies such as Vue.js, React, Next.js, JavaScript, and TypeScript.

My focus is not simply calling an AI API — it is integrating AI into reliable software architecture where models work together with application logic, data, permissions, APIs, and automation.

Readable code over clever code.
Simple architecture over unnecessary complexity.
AI where it adds value — not where it adds complexity.
Automation over repetitive manual work.
Measure before optimizing.
Reliability is a feature.

I value:

• Clean architecture — clear separation of responsibilities
• Maintainability — software should remain understandable as it grows
• Reliability — systems should fail predictably and recover gracefully
• Practical AI — use AI where it creates measurable product value
• Performance — optimize based on evidence and real bottlenecks
• Security — treat security as part of engineering, not an afterthought
• Automation — automate repetitive processes wherever it creates real value
