About

Senior Full-Stack Engineer & AI Architect with a passion for building autonomous, scalable systems that solve complex real-world problems. Currently pursuing an M.Tech in AI & ML from BITS Pilani (WILP), I specialize in combining robust cloud-native architectures with Generative AI and Agentic workflows. 🚀 Current Focus at Chitragupta Urban Tech: I lead the architecture of production-grade web applications serving 10k+ users. My work focuses on high-performance infrastructure, where I've successfully: - Reduced API latency by 20-30% through advanced PostgreSQL indexing and Redis caching strategies. - Architected automated ETL pipelines and event-driven systems to handle massive data volumes with zero manual intervention. - Established rigorous CI/CD standards and security protocols to streamline delivery for the engineering team. 💡 Innovation in AI & EdTech: As a core contributor to HowToAlgo, I evolved the platform from a launch-ready MVP to a sophisticated AI-driven ecosystem: - Agentic AI: Built automated content pipelines using Google ADK and Gemini, deploying agents via ECR/Fargate. - Vector Search: Implemented high-speed plagiarism detection using FAISS/Chroma and RAG-based architectures. - Cloud Optimization: Audited AWS access patterns to reduce infrastructure costs by 30% while improving performance by 40%. 🛠 Technical Arsenal: - Languages: TypeScript, JavaScript, Python, C++. - Frontend & Backend: Next.js, React, Node.js, Express, FastAPI. - Databases: PostgreSQL, MongoDB. - AI/ML: LLMs (Gemini, Bedrock), RAG, Vector Databases, Vertex AI, Google ADK. - Cloud & DevOps: AWS Certified Developer Associate (Lambda, DynamoDB, API Gateway, SQS), Docker, GCP, GitHub Actions. I thrive at the intersection of clean code and intelligent automation. Whether it's mentoring a team of developers or fine-tuning a vector search algorithm, my goal is to deliver measurable value and production-grade reliability.
