Hi, I'm Sumit Yadav πŸ‘‹

Building Intelligent, Scalable Software Systems

At the intersection of AI, Distributed Systems & Modern Software Engineering

Designing production-grade software that solves complex engineering problems through thoughtful architecture, scalable design and developer-centric engineering.

🟒 Open to conversations around technical leadership and building large-scale software systems. β€” Let's talk!


🧠 About Me

"I don't just write code β€” I architect systems that scale, lead teams that deliver, and solve problems that matter."

Lead Software Engineer with 7+ years shipping high-performance, cloud-native applications at enterprise scale. Currently at Accenture leading a team across full-stack and microservices architecture. I specialise in designing intelligent, scalable software systems, through distributed architectures, AI-native applications, and modern cloud-native engineering.

  • 🏒 Accenture β€” Tech Lead driving full-stack architecture & cloud solutions for enterprise-scale clients
  • πŸ€– Shipped production RAG pipeline β€” Next.js + Google Gemini + Pinecone + Vercel AI SDK
  • ⬑ Built AlgoLens β€” 25+ interactive DSA & system design visualizers, built from scratch with zero animation libraries
  • ⚑ Built real-time notification engine with SSE, Redis fan-out & multi-channel delivery
  • πŸ“ Deep expertise in system design β€” SAGA patterns, consistent hashing, distributed transactions
  • ✍️ Technical author β€” 8 published deep-dives on distributed systems & AI engineering

πŸ† Engineering Philosophy

✦ Build for scale from day one β€” not as an afterthought
✦ Make trade-offs explicit β€” every architectural decision is a conversation
✦ Optimise for developer experience β€” great DX leads to great products
✦ Mentor relentlessly β€” a rising tide lifts all boats
✦ Stay curious β€” the best engineers never stop learning
✦ Simplicity scales better than cleverness
