About me

I am a Senior Software Engineer with more than 10 years of experience building high-performance backend systems, data pipelines, and scalable microservices. My current focus is production AI and LLM application engineering, where I design reliable systems that combine deterministic logic with modern language model capabilities.

I have worked across healthcare, telecom, ERP, e-commerce, and FinTech, which has given me a broad perspective on building software for complex business environments. I am especially experienced in Python and its ecosystem, including Django, FastAPI, Flask, Celery, and asyncio, and I enjoy solving problems involving concurrency, performance, and system reliability.

In recent roles, I have built production AI solutions using OpenAI, Anthropic Claude, Azure OpenAI, and Amazon Bedrock. My work has included RAG pipelines, agentic and multi-agent systems, structured extraction, prompt engineering, and LLM-integrated services deployed in cloud environments.

I also have strong hands-on experience with PostgreSQL, RESTful API design, Docker, Kubernetes, Terraform, and CI/CD automation. I have contributed to infrastructure and deployment workflows across AWS, Azure, and GCP, and I am comfortable working across the full software delivery lifecycle.

As a founder and lead engineer, I have built a B2B SaaS platform for autonomous AI voice and email agents, and I have also led modernization efforts for legacy systems, including migrations from C++ to Python. I value clean architecture, scalable design, and practical engineering decisions that support long-term maintainability.

Overall, I bring a combination of backend engineering depth, cloud and DevOps experience, and modern AI product development. I am interested in roles where I can continue building advanced software systems and production-grade AI solutions that create measurable business value.
