Professional Experience

Software Developer · BCEL (Banque pour le Commerce Extérieur Lao)

Built and maintained core features of BCEL's mobile banking platforms serving 2M+ customers, owned backend development for secure online-banking services, and led a junior developer team across delivery and maintenance projects.

Flagship initiatives

  • OneCare — Real-Time Support Platform (2019–2020). Led a team to build a chat-based customer support system from scratch (customer app, agent console and real-time backend), lifting daily inquiry throughput 430% (200 → 1,300) and reducing in-branch visits 30% while cutting response times from hours to minutes. Technologies:Svelte · Vue · Node.js · WebSockets · Oracle · Redis
  • Cardless Cash Withdrawal (2020–2021). Pioneered the first cardless ATM withdrawal in Laos, leading end-to-end development of a secure, time-limited QR withdrawal feature and coordinating firmware rollout across 1,000 ATMs nationwide — reaching 25% adoption within six months and eliminating 100% skimming fraud. Technologies:Java · NCR / NDC integration · QR technology
  • Smart POS Modernisation (2023–2025). Led the technical build of an Android Smart POS platform, replacing 2,500 legacy terminals and certifying BCEL as a direct acquirer for Visa, Mastercard, Amex, UnionPay and JCB — enabling seamless card acceptance and QR payment acceptance while giving the bank full control of the merchant experience (digital receipts, sales analytics, OTA updates). Technologies:Svelte · Android · Capacitor SDK · Kotlin · Card Acquisition · ISO-8583 · EMV Protocol
  • OneCampus — School Fee Payments (2021–2022). Designed and built a full-stack school-payment platform integrated with BCEL's mobile app, replacing cash collection with instant in-app tuition payments and automated reconciliation — now serving 1,000+ schools and accessible to 2M customers. Technologies:Vue · Express.js · Oracle on AWS RDS · Java · Jenkins (CD/CI)
