What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth in AI technologies.

As a Senior AI Developer with over a decade of experience, I specialize in designing, deploying, and optimizing AI-powered systems. My journey has equipped me with a robust skill set in building scalable applications, particularly in the realm of natural language processing and machine learning. I have successfully engineered RAG-based knowledge assistants leveraging cutting-edge technologies like GPT-4 and LangChain, ensuring enterprise-grade solutions for Q&A and summarization.

Throughout my career, I have fine-tuned transformer models and developed LLM inference layers that support real-time streaming and cloud-native tooling. My collaborative approach has allowed me to work cross-functionally with design and product teams, delivering AI-powered tools that yield measurable business outcomes. I take pride in mentoring junior developers and conducting design reviews, ensuring best practices in architecture and security are upheld.

My educational background in computer science and machine learning has laid a strong foundation for my technical expertise. I am passionate about leveraging AI to solve complex problems and continuously seek opportunities to innovate and improve processes within the AI domain.
