About

Senior Software Engineer (Java / .NET) with 9+ years building and scaling enterprise systems across retail, F&B, logistics, and integration-heavy platforms. I focus on backend architecture: microservices with .NET / Java & Spring Boot, event‑driven systems using Kafka/RabbitMQ, and cloud-native deployments on AWS + Kubernetes with relational databases (PostgreSQL, SQL Server, Oracle, MySQL) and Redis caching. I’ve led teams on large modernization and performance projects for Japanese clients (legacy → Spring, secure reporting, high‑volume back‑office systems) and designed high-traffic ordering platforms for major F&B brands, including web and API backends, POS/payment/delivery integrations, and central logistics/OMS/CRM services. My work typically covers the full lifecycle: architecture → implementation → production stabilization, plus reverse‑engineering undocumented systems, performance tuning, and writing the documentation needed for long-term maintenance. I enjoy owning solutions end-to-end, collaborating closely with BA/Product/QA/DevOps, and mentoring engineers.

Project Leader

Oct 2016 – Feb 2024 · 7 yrs 4 mos · Ho Chi Minh City, Vietnam · On-site

Led 15+ outsourced projects for Japanese clients as Developer → Project Leader, managing teams of 2–12 engineers and driving modernization, performance and security improvements across multiple enterprise systems. Acted as architect and technical consultant for a healthcare platform built with Java 8, Spring Boot 2.x, Spring Cloud (Eureka), Kafka, PostgreSQL and S3, designing microservices and reliable device‑integration flows that prevented database overload and improved ingestion reliability. Delivered a large legacy‑to‑Spring migration for a public‑sector client, and significantly optimized a VB.NET desktop and batch system for accounting/stock/shipment by resolving memory leaks, deadlocks and slow queries, reducing nightly batch runtimes from over 4 hours to under 60 minutes. Additionally defined architecture and RBAC for an e‑learning platform and built a secure reporting solution for the utility sector (ASP.NET Core, PostgreSQL), while contributing to workforce scheduling, IoT proof‑of‑concept work and multiple Java/Oracle enterprise systems.
