Nishant Sharma — Backend Software Engineer

Jaipur, India · TypeScript, Node.js, Express, PostgreSQL, Prisma, React.js

• Built a three-sided property-verification marketplace end-to-end — 18 Prisma/PostgreSQL models and 106 REST endpoints behind role-isolated JWT auth (buyer / seller / admin) that makes cross-role token reuse structurally impossible.
• Engineered the marketplace money logic: seller earnings, settlement and refund APIs, with commission splits frozen on the purchase row at transaction time so historical records stay correct even as policy changes.

Jaipur, India · Java, Spring Boot, MySQL, TypeScript

• Developed the backend of an employee-appraisal platform, designing a layered Spring Boot service on MySQL with DTO-isolated API contracts and global exception handling.
• Implemented Spring Security 6 with JWT-based role access for HR, manager and employee actors, exposing REST endpoints consumed by the team’s React + TypeScript dashboard.

Video platform backend with an AI-powered RAG engine — Whisper transcription, local embeddings and pgvector semantic search, running on a deliberately tiny 1 GB EC2 box.

• Engineered a RAG pipeline where a decoupled FastAPI microservice streams audio to Groq whisper-large-v3, embeds chunks locally with all-MiniLM-L6-v2, and answers through pgvector search with cited sources.
• Runs live on a 1 GB-RAM EC2 t3.micro by design — pgvector inside Postgres rather than a separate vector database, cloud Whisper instead of local inference.
• Three Docker containers shipped via GitHub Actions CI/CD behind Nginx SSL termination and Cloudflare, cutting deploys from 15 minutes to 90 seconds at under $10/month.

Anonymous messaging platform with AI-assisted replies — structured Groq output, hardened auth, and a cascade-safe Postgres schema.

• Built a custom NextAuth credentials flow — 6-digit expiring email verification via Resend, bcrypt-hashed passwords, and Zod validation on every input.
• Designed a cascade-safe Prisma schema with transactional account deletion, relational integrity and indexed retrieval, using UUIDv7 keys to keep index lookups sequential.
• Integrated Groq Llama 3.3 through the Vercel AI SDK with Zod-enforced structured suggestions, an 8-second timeout guard, and parallel dashboard loads.

Full-stack Kanban platform for job hunting — React Server Components, optimistic drag-and-drop, and O(1) float ordering.

• Built on Next.js App Router with React Server Components to eliminate client-side loading waterfalls, with end-to-end type safety between Server Actions and the database layer.
• Implemented a dnd-kit Kanban board with optimistic UI updates and an O(1) float ordering scheme, so reordering a card writes one row instead of renumbering the column.
• Wired Better Auth database hooks to auto-provision a 5-stage pipeline on registration, and shipped a multi-stage Docker build on Next.js standalone output to AWS EC2 behind Nginx with Certbot SSL renewal.

Real-time movie discovery app whose trending list is generated from live user search patterns rather than a static feed.

• Built a trending algorithm that captures and aggregates user search queries in an Appwrite database to rank titles in real time.
• Engineered debounced search to cut redundant API calls, on a mobile-first responsive UI deployed to Vercel via automated builds.

C++ banking simulation engine that replaced text-file persistence with binary serialisation for a 300% throughput gain.

• Rewrote the storage layer from parsed text I/O to raw binary serialisation, achieving 300% faster read/write operations on account transactions.
• Structured the engine around SOLID OOP boundaries so accounts, transactions and persistence stay independently testable.

This site — a browser CLI over a fully pre-rendered static document, so it reads well to both humans and crawlers.
