Hello! I'm a Full Stack Developer specializing in AI integration and LLM-powered applications. With 4+ years of experience delivering solutions across startups and enterprise projects, I enjoy working on problems where good engineering actually changes how a business operates. I'm particularly drawn to AI systems where the technical challenge and the real-world impact meet in the same place. 𝐀𝐈 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 & 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 I build production-ready AI features directly into your application. From RAG pipelines and vector search using Pinecone, ChromaDB, and FAISS, to autonomous multi-agent systems using LangChain and CrewAI, I integrate it all cleanly into your existing stack. I've built document Q&A systems that cut down manual research time significantly, deployed AI chatbots for SaaS platforms, and designed automated workflow agents for operational teams. If you're in SaaS, fintech, or developer tooling, there's a good chance I've worked on something close to your problem. 𝐋𝐋𝐌 𝐄𝐯𝐚𝐥𝐮𝐚𝐭𝐢𝐨𝐧, 𝐏𝐫𝐨𝐦𝐩𝐭 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 & 𝐅𝐢𝐧𝐞-𝐓𝐮𝐧𝐢𝐧𝐠 𝐃𝐚𝐭𝐚 I have hands-on experience designing LLM evaluation frameworks, building benchmark task suites, and collecting high-quality SFT data across real model evaluation projects. I also do prompt engineering across multi-turn, few-shot, and RAG-based contexts using the OpenAI API, Claude API, and open-source models. I understand what actually makes a model perform reliably in production, not just on paper. 𝐍𝐨𝐝𝐞.𝐣𝐬 / 𝐍𝐞𝐬𝐭𝐉𝐒 / 𝐄𝐱𝐩𝐫𝐞𝐬𝐬.𝐣𝐬 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 I specialize in building scalable backend systems using Node.js, Express, and NestJS. REST APIs, microservices, real-time WebSocket systems, and AI-ready backend architecture are all in my wheelhouse. I work comfortably with PostgreSQL, MySQL, and MongoDB, and I keep performance and clean architecture at the center of everything I build. 𝐑𝐞𝐚𝐜𝐭.𝐣𝐬 & 𝐍𝐞𝐱𝐭.𝐣𝐬 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 I build dynamic, responsive, and SEO-optimized frontends using React.js and Next.js, including streaming LLM interfaces and AI-powered chat UIs. From interactive SPAs to high-performance SSR apps, I make sure your frontend is fast, scalable, and easy to maintain. 𝐀𝐧𝐠𝐮𝐥𝐚𝐫 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 For larger, structured frontend projects I use Angular with TypeScript, modular design, and reactive programming. I've built dashboards, data-driven interfaces, and enterprise-grade systems where long-term maintainability really matters. 𝐀𝐒𝐏.𝐍𝐄𝐓 𝐂𝐨𝐫𝐞 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 I also work with ASP.NET Core for businesses on Microsoft stacks or with enterprise-level requirements. Whether it's secure APIs or full-featured web apps, I deliver .NET solutions that hold up in production. 𝐖𝐡𝐲 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 𝐌𝐞? 𝐀𝐈 + 𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 𝐢𝐧 𝐎𝐧𝐞: Most developers can build an app or bolt on a chatbot. I do both in one coherent system, so you don't end up with two contractors pointing fingers at each other. 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧-𝐅𝐢𝐫𝐬𝐭 𝐌𝐢𝐧𝐝𝐬𝐞𝐭: I follow best practices for performance, security, and maintainability across every project I take on. 𝐑𝐞𝐚𝐥 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 𝐒𝐨𝐥𝐯𝐞𝐫: I think through the actual business problem first and engineer a solution that fits, not just code that runs. 𝐅𝐨𝐜𝐮𝐬𝐞𝐝 𝐄𝐧𝐠𝐚𝐠𝐞𝐦𝐞𝐧𝐭: I take on a small number of projects at a time so each one gets real attention, not a copy-paste solution. 𝐓𝐫𝐚𝐧𝐬𝐩𝐚𝐫𝐞𝐧𝐭 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧: I keep you in the loop at every stage and work closely with you to make sure your vision gets executed the right way. Send me a message describing your project and I'll get back to you within 24 hours with a clear view of how I can help and what it would take to get it done.
