What I'm looking for

I’m looking to build production-grade cloud-native products—scalable microservices, high-performance APIs, and LLM-powered automation (RAG, AI workflows)—with strong engineering ownership, technical leadership, and fast iteration cycles for measurable business impact.

I’m a Senior FullStack&AIEngineer with 8+ years of experience designing and building scalable SaaS platforms, AI-powered applications, and enterprise software for global teams and US-based clients. I specialize in Python (FastAPI, Django), modern frontend development (React, Next.js), and cloud-native engineering (AWS, Kubernetes), with a strong focus on system architecture, DevOps, and CI/CD automation.

In my recent role, I led development of scalable AI-powered applications, building distributed backends, RESTful APIs, and microservices for enterprise-scale workloads and real-time processing. I integrated LLM workflows—RAG pipelines and AI automations—using OpenAI APIs and LangChain, and deployed and maintained production infrastructure on AWS with Docker, Kubernetes, Terraform, and GitHub Actions. I also optimized scalability and reduced API latency by 40% through query optimization and Redis caching.

Earlier, I built full stack web applications and backend services that improved performance and reliability while maintaining CI/CD pipelines and containerized deployment workflows. I’ve delivered real outcomes across projects, from a real-time trading analytics dashboard to an AI customer support platform that reduced manual workload by 60%, and an AI document processing and comparison system leveraging OCR and LLM-based pipelines.
