I build AI-powered applications and full-stack products, taking ideas from concept to working software. My work covers both AI engineering and application development. I don't just integrate LLM APIs — I also work with open-weight models, fine-tuning, AI agents, and the engineering required to turn them into usable products. **What I work on:** - **AI Agents & LLMs:** Multi-agent systems, tool calling, RAG, AI workflows, and OpenAI/Gemini integrations. - **Model Fine-Tuning:** Fine-tuning open-weight models using LoRA/PEFT, dataset preparation, evaluation, and inference. - **Full-Stack Development:** Building SaaS applications and MVPs using React, Next.js, Node.js, Python, and databases. - **Machine Learning & Computer Vision:** Model development, image analysis, signature verification, and ML pipelines. - **Deployment:** Docker, cloud infrastructure, APIs, and backend services. **Some things I've built:** - WriteBookAI – An AI writing SaaS with author voice profiles and structured content-generation workflows. - CryptoClever – A multi-agent crypto analysis engine combining technical indicators and market analysis. - Enterprise IT Incident Triage AI – Fine-tuned an open-weight language model using LoRA/PEFT for incident classification. - Cheque Signature Verification – A computer vision project combining signature similarity analysis and human review. I enjoy working on problems where AI and software engineering come together — whether that's building an MVP from scratch, fine-tuning a model for a specific task, or integrating AI into an existing application. If you have an idea or a technical problem you're trying to solve, let's discuss it.
