Hi, I'm
Aung Kaung Khant
Full Stack Developer — Backend Focused
I build the backends that shops, riders and cashiers run their day on.
Backend-focused full stack developer with 4+ years shipping production e-commerce, marketplace, payment and point-of-sale systems. Strongest in NestJS, TypeScript and Laravel; ships end to end with Next.js, React and Ionic. Led the backend for a 4-developer e-commerce team.
Experience
Full Stack Developer — Ravus Law Chamber Company
Raveon Live Mini, a live event & artist tipping platform
The RubexPay gateway has no webhook, so a guest who tips and closes the app would strand the payment. A scheduled reconciliation job settles anything left unconfirmed.
- Built the Laravel API, Next.js admin and guest tipping PWA solo, owning the product end to end.
- Integrated the RubexPay payment gateway with a reconciliation job, so no tip is lost if the app closes.
- Built payout dashboards with PDF/Excel reports, so organizers settle artists without spreadsheets.
Backend Developer — YEC Company
Blingo (blingo.app), an e-commerce & consignment platform
I architected the backend from scratch, grouped by business process. Notifications and rewards run through an event layer after the transaction commits, so the core flows never wait on them.
- Led the backend for a 4-developer team; post-commit events stop rewards firing on failed orders.
- Removed N+1 queries from listings and reports, so pages stay fast as the catalog grows.
- Designed payments for how Myanmar pays (bank, wallet, QR, cash), so no customer needs a card.
- Built role-based access and audit logs for 4 staff roles, so warehouse and accounting need no admin rights.
Freelance Backend Developer — MyTogether Shop
Marketplace & delivery API, live on Google Play
Nothing slow belongs on the request path. Broadcast notifications and payment-timeout jobs run as BullMQ workers, and Redis carries the cache and the short-lived redeem tokens.
- Built the delivery backend (shops, orders, riders); BullMQ jobs auto-cancel unpaid orders.
- Added realtime order tracking with WebSockets and push notifications.
Projects
PhiLo POS — multi-branch inventory & point of sale
Co-built outside work hours, in production with paying customers
A cashier cannot stop selling because the line dropped. Every sale lands in a local store with ULID keys, and a background sync reconciles it when the connection returns.
- Co-built outside work hours, now in production with paying customers; I lead the apps and wrote the API.
- Built offline-first sync, so cashiers keep selling through internet outages and data reconciles on its own.
- Shipped one React codebase to Android, iOS and desktop, with receipt printer and scanner support.
DevPulse AI — bilingual RAG document Q&A
Document and code Q&A in Burmese or English
Burmese retrieval was failing. Translating the question into English for the retrieval step only, while still answering in the language it was asked in, fixed it.
- Answers questions on documents and code in Burmese or English; cut time to first citation from 31s to 2.5s.
