01 About Me

The person behind
the code.

Hey — I'm Mann, a Full Stack Developer with 1.5+ years of shipping production systems at pace. I specialize in building end-to-end platforms that are fast, secure, and maintainable.

My work spans distributed microservice backends, real-time event-driven systems, multi-vendor e-commerce, and performance-optimized APIs. I've contributed to 12+ live client projects across diverse industries — from B2B marketplaces to HRMS platforms.

Currently at Demaze Technologies architecting a 20-service BigCommerce platform serving 3,000+ SKUs, while finishing my Bachelor of Engineering at L.J. University, Ahmedabad (2022–2026).

Where I've built things.

Demaze Technologies

Full Stack Developer

Nov 2025 – Present ● Current
  • Architected a 20-service Express microservices backend (TypeScript) with strict RBAC — covering product catalog, multi-vendor inventory, cart/checkout, Razorpay, order lifecycle, coin wallet, referral engine, discounts, shipping, CMS, and admin tooling
  • Implemented Redis Pub/Sub for async cross-service event communication — fully decoupled order, inventory, and notification services, cutting inter-service latency by ~35% vs synchronous REST chaining
  • Designed PostgreSQL schemas with TypeORM — relational mappings, composite indexing, migration versioning; resolved N+1 query issues via eager loading and EXPLAIN ANALYZE profiling, cutting slow queries by 60%
  • Enforced idempotency keys on Razorpay webhook handlers; implemented Redis caching on high-read endpoints reducing DB load under peak traffic
  • Built frontend modules across 4 portals (Customer, Vendor, Warehouse, Admin) using React, TanStack Router, NavBlocker, scroll-to-first-error UX, and Sentry error tracking
  • Configured GitHub Actions CI/CD with Husky pre-commit hooks running TypeScript + lint checks before every push — cut deployment failures by 50%

Alliedge Technologies

Full Stack Developer

Nov 2024 – Nov 2025
  • Contributed to 12+ live client projects; led end-to-end development of a B2B multilingual marketplace (EN/FR) connecting Canadian wholesalers and buyers — vendor analytics dashboards, dynamic listings, and ratings system
  • Optimized API performance using TanStack Query caching and query-level indexing — reduced average response times by 40% and improved scalability under concurrent load
  • Implemented comprehensive security: JWT refresh token rotation, rate limiting, Helmet.js, CORS, OTP/email verification, RBAC, and MetaMask blockchain authentication
  • Built real-time chat with Socket.IO + Redis Pub/Sub; integrated Stripe payment webhooks with live socket confirmations; added FCM push notifications, bulk Excel import, and automated PDF billing
  • Developed a multi-portal HRMS (Super Admin, Client Admin, Employee) with dynamic payroll templates, attendance/leave management — optimized aggregate queries improving report speed by 30%
  • Managed production deployments across AWS EC2, Hostinger VPS, and Azure App Service with Nginx reverse proxy, PM2, and Certbot SSL
