Work Experience

Software Engineer

Car Wizard Pvt Ltd (VahanHelp)

May 2024 - Apr 2026 Jhansi, Uttar Pradesh
  • Owned end-to-end architecture of Node.js + MongoDB backend on AWS EC2 — live Play Store app with OTP auth, dealer onboarding, Razorpay payment integration, and multi-role access for customers and dealers.
  • Built React Native (Expo) mobile UI with Tailwind CSS — multi-step dealer onboarding flow, cursor-based infinite scroll feed, and S3 + CloudFront-backed image delivery with LQIP blur previews; pixel-perfect conversion from Figma designs to production-ready interfaces.
  • Integrated third-party services including RC verification, WhatsApp messaging, AWS S3 media uploads, and Firebase push notifications via async REST endpoints with error handling and response caching.
  • Built a responsive React.js + Material UI dashboard with role-based access control — clean component architecture, reusable UI library, and accessible interfaces aligned to Figma specs across Admin, KAM, and RTO roles.
  • Developed complex financial reporting dashboards with NOC/transfer case categorization, split-month cost allocation, nested field Excel export, and role-based filter visibility.
  • Automated Challan lookup via API Mall using async background tasks — reduced manual lookup time by ~70% with error handling and response caching; integrated results into real-time dashboard views.

Projects

CollegeHuntin

Next.jsTypeScriptReact.jsTailwind CSSNode.jsMongoDBGroq LLaMA 3.3
  • Built entire platform from scratch using Next.js + TypeScript deployed on Vercel — RESTful APIs with Node.js + MongoDB covering college listings, lead submissions, and blog management with JWT auth and protected admin routes.
  • Designed and implemented fully responsive, accessible UI with Tailwind CSS and Material UI — converted Figma wireframes into production-quality interfaces with consistent spacing, layout, and cross-browser compatibility.
  • Integrated Groq Llama 3.3 70B LLM into production app — custom /api/chat endpoint with multi-turn conversation history, domain-specific prompt engineering, and real-time typewriter streaming replacing a static chatbot.
  • Currently managing and maintaining the full platform end-to-end in production; uses Cursor and GitHub Copilot for development speed while validating all AI-generated output before merging.

PoolPay

PythonFastAPIPostgreSQLSQLAlchemyOpenAI API
  • Built a fintech-style shared group wallet API with async endpoints, relational data modeling (pools, members, transactions, invites), RBAC (Admin/Member/Viewer), per-member spending limits, and full audit logging.
  • Atomic transactions via SQLAlchemy sessions — balance deduction, member spending update, and audit logging either all succeed or all roll back together, preventing data inconsistency under concurrent requests.
  • Separated business logic into a dedicated Service layer (WalletService, TransactionService) using the Repository pattern to decouple DB access — swapping PostgreSQL or adding caching requires zero changes to business logic.
