Full-Stack & Systems Engineer | AI / ML & Distributed Workflows | Cloud Architecture
Final-Year B.Tech Computer Science & Engineering @ KIIT University, Bhubaneswar
I design and build resilient, deterministic full-stack applications, distributed AI data pipelines, and blockchain systems. My engineering philosophy centers on anti-hallucination code execution, strongly typed full-stack architectures (TypeScript + Next.js/React + Prisma), and high-throughput Python/Go backends deployed across cloud-native environments (Docker, Kubernetes, AWS, Vercel, Render).
- 💻 Core Domains: Distributed Systems, Full-Stack Web Development, Data Engineering, LLM Agentic Workflows, Smart Contracts.
- 🛠️ Current Focus: Architecting enterprise-grade event-driven microservices, AST-sandboxed AI code generation, and financial econometrics.
- 🎯 Engineering Principle: Always prefer deterministic computation and verifiable code execution over raw LLM guessing.
