Piyush Mishra
Senior Full-Stack Developer (AI & SaaS)
10 years shipping software — after 2 running plant procurement
I build production-ready full-stack systems — from multi-tenant SaaS platforms to AI-powered workflows and real-time applications. I've led teams, architected systems serving millions of users, and shipped everything from OAuth integrations across 50 platforms to RAG-based research copilots. Currently building RFQTrace and available for freelance Next.js and Firebase projects.
About Me
I’m a senior full-stack engineer with 14 years of professional experience — ten building software, and four before that as an operations engineer handling ₹150 crore of power plant procurement and as a marketing manager. The industrial background is why I build for manufacturers rather than about them.
I taught myself to code in 2016 after an MBA at IIM Indore, and was tech lead on a 10-person team at that first engineering job by the time I left it.
My work spans SaaS integrations, authentication systems, AI-powered features (RAG, summarization, workflow intelligence), and cloud-native architectures. I focus on building systems that balance speed, reliability, and long-term scalability.
I enjoy leading teams, mentoring engineers, and collaborating closely with product and design to turn ambiguous ideas into impactful, production-ready solutions.

RFQTrace
2026 – PresentBuilding a multi-tenant RFQ and supplier quote management platform for small-to-mid-size manufacturers — the segment priced out of enterprise procurement suites.
Key Achievements:
- •Built multi-tenant architecture with organisation-level data isolation and role-based access control across 5 roles
- •Structured quote comparison on first-class fields (unit price, lead time, MOQ, payment terms) rather than free text
- •One-link supplier portals that produce structured data instead of PDF attachments someone has to transcribe
- •Offline-first caching with Dexie.js synced against Firebase RTDB, so the tool stays usable on plant floors and supplier visits
