Full Stack Developer · AWS Certified · 3★ CodeChef
Sai Sarthak Mohapatra.
Building scalable distributed systems, cloud-native SaaS platforms, and pixel-perfect experiences that feel effortless.
I'm a Full Stack Developer with 4+ years of experience building scalable distributed systems and cloud-native SaaS platforms at SysCloud. I specialize in React, TypeScript, Node.js, GraphQL, PostgreSQL and AWS — from crafting pixel-perfect interfaces for enterprise backup applications to engineering high-throughput orchestration engines serving 10K+ global users. I've implemented secure authentication workflows with OAuth 2.0 and PKCE, built GenAI-assisted operational diagnostics using Claude APIs, designed JSON-driven UI architectures that ship without redeployment, and directed multi-region deployments across US and Tokyo infrastructure. I'm AWS Certified and a 3-star rated competitive programmer on CodeChef. I don't just write code — I architect systems that scale invisibly and deliver experiences people genuinely enjoy using.

Selected Work
Things I've built.
Each project represents a unique challenge — from AI-powered platforms to distributed orchestration engines.
MeetArc — AI Meeting Intelligence Platform
Full-stack AI-powered meeting intelligence platform built across three microservices. Next.js 16 frontend with React 19 Compiler, MUI v7, TanStack Query v5, and NextAuth/Supabase auth. Offline-first IndexedDB upload queue with exponential backoff and cross-session recovery. Express.js backend with Prisma/Neon PostgreSQL, BullMQ/Redis job processing, and dual AI integrations (Claude + OpenAI). Autonomous meeting bot using rebrowser-playwright for stealth Google Meet recording with state-machine lifecycle, three-layer participant detection, grace period auto-leave, and two-phase Supabase Storage upload with crash recovery. Multi-cloud storage (AWS S3, Azure Blob, Supabase), Prometheus metrics, and fully containerized with Docker Compose.
Backup Jobs 3.0
Distributed job-orchestration engine built with Node.js, GraphQL, PostgreSQL and AWS. Improved platform reliability by 40% and enabled AI-assisted failure diagnostics using Claude-based LLM pipelines for 10K+ enterprise users.
Product Design Framework
Scalable React component-driven architecture that reduced frontend code changes by 70%. Includes JSON-driven UI enabling runtime interface configuration without redeployment, improving iteration velocity by 40%.
Enterprise Security & Compliance Suite
Modular backend architecture supporting Ransomware Detection, Compliance Monitoring, eDiscovery, Archival and Data Insights. Secure OAuth 2.0 with PKCE and AWS Lambda authorizers.
ScreenAppBot — MeetArc
Universal meeting bot to record Google Meet, Zoom, and Microsoft Teams with a single API. Production-ready, free to use, extend, and scale.
