What I'm looking for

I'm looking for a long-term remote opportunity where I can build scalable products, solve challenging technical problems, and collaborate with a strong engineering team. I value ownership, continuous learning, and the opportunity to contribute to impactful software and AI solutions.

I am a Senior Full Stack & AI Engineer with over 9 years of experience designing and building scalable SaaS platforms, enterprise web applications, and AI-powered products. My expertise spans Python, Django, FastAPI, React, Next.js, TypeScript, PostgreSQL, cloud infrastructure, and modern software architecture.

In recent years, I have focused on production AI systems, including LLM applications, Retrieval-Augmented Generation (RAG), AI workflow automation, document intelligence, and enterprise knowledge assistants. I have designed AI solutions for document summarization, semantic search, classification, entity extraction, and AI-assisted workflows using modern AI APIs and vector databases.

Throughout my career, I have modernized legacy systems, designed secure APIs, optimized application performance, built scalable backend services, and developed intuitive frontend experiences. I also have experience leading engineering teams, mentoring developers, conducting code reviews, and delivering reliable production software from architecture through deployment.

I enjoy solving complex technical problems, building products that have measurable business impact, and collaborating with cross-functional teams. I am particularly interested in AI, developer tools, workflow automation, cloud-native platforms, and products that combine great engineering with an excellent user experience.

I am looking for long-term opportunities where I can contribute both technically and strategically while continuing to build innovative software that scales.
