🚀 Full Stack Developer | 👨‍💻 Former Mechanical Engineer | 💻 Python · FastAPI · Django · React · TypeScript · AI/ML | 📈 Algo Trading Enthusiast

Welcome to my GitHub profile! I'm Vipul Kavar, a passionate full-stack developer specializing in Python, FastAPI, Django, React, and TypeScript, with a strong focus on AI-powered applications (LLMs, RAG) and scalable microservices. With 3+ years of hands-on experience, I've transitioned from mechanical engineering into software — building AI-integrated products across FinTech, EdTech, HealthTech, and PropTech, and exploring algorithmic trading on the side. I also lean heavily on AI-assisted development tools (Claude Code, Codex) to ship faster. Let's embark on a journey through my coding endeavors!

• AI/ML & LLMs: Building applications with LLM integration, RAG pipelines, and prompt engineering
• Backend Engineering: Scalable APIs, microservices, and domain-driven design
• Share Market & Algo Trading: Automated trading systems and financial market analysis
• Python & C++: Robust backend development and problem-solving

• Languages: Python, TypeScript, JavaScript, C++
• Frontend: React, TypeScript, Redux, HTML5, CSS3, jQuery
• Backend: FastAPI, Django, Django REST Framework (DRF), REST APIs, gRPC
• AI/ML: LLM Integration, RAG, Prompt Engineering, Pinecone (Vector DB), Audio Transcription, AI-Assisted Dev (Claude Code, Codex)
• Architecture: Microservices, Domain-Driven Design (DDD), Serverless
• Messaging & Queues: Redis, RabbitMQ, Celery, Pub/Sub, AWS SQS, AWS EventBridge
• Cloud & DevOps: AWS (Lambda, S3, ECS, SES), Docker, Git
• Databases: PostgreSQL, MongoDB
• OS: Ubuntu (Linux), Windows

I'm a firm believer in continuous learning and staying at the forefront of technology. Areas I'm currently exploring:

• DevOps: Infrastructure automation, CI/CD pipelines, and cloud deployment strategies
• AI Tools Utilization: Leveraging AI-assisted development tools (Claude Code, Codex, Antigravity) to accelerate prototyping, code generation, and delivery
• Algorithmic Trading: Building and back-testing automated trading strategies
• C++ & Competitive Programming: Sharpening algorithmic thinking and problem-solving

I've worked on a range of AI-powered and full-stack projects — most are professional/client work, so here are a few highlights:

1. Real Estate Platform (PropTech): Microservices-based platform (FastAPI + React) using gRPC for internal communication and AWS Lambda/SES/EventBridge for concurrency and scheduled automation — bulk listings, intelligent search, real-time bidding, and transactions.
2. ShareMarket AI Bot (FinTech): RAG-powered chatbot that answers stock-market questions from a PDF knowledge base using Pinecone embeddings + ChatGPT, with Stripe subscriptions.
3. InfoSummarize AI: Extracts and summarizes content from YouTube, blogs, and news APIs, then converts summaries to audio.
4. Algo Trading: Distributed trading system implementing custom strategies with Redis, RabbitMQ, Celery, and Pub/Sub.
5. AI/ML Samples: Public samples including face recognition, recommendation systems, and sentiment analysis.
