About

Professional summary

I am a Senior Full Stack Developer with more than seven years of experience delivering and supporting critical web applications, REST APIs, microservices, and high-volume systems. I take end-to-end ownership of projects, from requirements gathering and architecture to implementation, deployment, and production support.

My backend experience includes PHP, Laravel, Lumen, Node.js, Nest.js, Python, FastAPI, and Go. I build scalable services, integrations, asynchronous workflows, and data-intensive applications with a focus on clean architecture, SOLID principles, performance, and maintainability.

On the frontend, I work with JavaScript, TypeScript, Vue.js, Angular, jQuery, HTML, and CSS. I am comfortable developing complete product features across frontend and backend layers while collaborating on requirements, data modeling, and user-focused solutions.

I have strong experience with PostgreSQL, MySQL, SQL Server, Redis, Kafka, queues, database replicas, query optimization, and caching. My work has improved API response times, reduced database load, and made large reporting workflows reliable at scale.

I also work with cloud and DevOps practices using Docker, AWS, OCI, Kubernetes, Linux, GitHub Actions, CI/CD, and Sentry. I have deployed and maintained production infrastructure and actively investigate and resolve critical production issues.

I am experienced in applied Generative AI, including LLMs, RAG, hybrid search, embeddings, pgvector, OpenAI API, OpenRouter, MCP, and AI agents. I use AI-assisted development tools responsibly, maintaining rigorous human review for architecture, security, testing, and code quality.
