Senior Full-Stack Engineer with 10+ years of experience and a Master's degree in Computer Science. $50K+ earned on Upwork across 10 completed jobs with 2,751+ billable hours. I build production-grade web applications end-to-end - from React/Next.js front-ends to Node.js and Python (FastAPI/Django) back-ends, deployed on AWS, Azure, or GCP. My core strength is owning the full stack: I can take a product idea, design the architecture, ship the UI, build the APIs, set up the database, deploy to cloud, and integrate AI capabilities (OpenAI, Claude, LLM APIs) where they genuinely add value - without you needing to coordinate three different specialists. Whether you're a startup shipping your MVP, an SME modernizing a legacy stack, or a product team adding AI features to an existing SaaS, I deliver code that runs in production, not prototypes that need a rewrite. ✅ What I Can Do For You: ▪️ Full-Stack SaaS development. End-to-end delivery with React, Next.js, Node.js, Python (FastAPI/Django), PostgreSQL, and MongoDB. Production deployment with Docker, AWS, and GCP. ▪️ AI Integration into existing web apps. Integrate OpenAI, Claude, and other LLM APIs into your SaaS. Build RAG pipelines, custom chatbots, and document intelligence workflows using LangChain, LlamaIndex, and vector databases (Pinecone, Weaviate). ✅ My Technology Stack: ▫️ Frontend: React, Vue.js, Angular, HTML5/CSS, Bootstrap ▫️ Backend: Node.js, Java (Spring Framework), C#/.NET (ASP.NET Core, .NET Framework), Python ▫️ Machine Learning & AI: Python, PyTorch, TensorFlow, OpenCV, scikit-learn, NLTK, BERT, Apache Spark, XGBoost ▫️ Computer Vision: OpenCV, YOLOv5, Tesseract OCR, deep learning for image recognition ▫️ Data: PostgreSQL, MongoDB, Redis, MySQL, Microsoft SQL Server, Oracle Database ▫️ Cloud/DevOps: AWS, Azure (including Azure Bot Service), Google Cloud Platform ▫️ Currently expanding into: LLM integration (OpenAI, Claude APIs), RAG pipelines with LangChain, and modern AI agent workflows ✅ Let's Get Started: If you have a full-stack build, a legacy system to modernize, or an AI feature you want shipped properly inside a real product, send me a brief message describing your goals. I'll respond within 24 hours and am available for both short engagements and long-term retainers.
