01. About Me

I'm a Java Developer at BHSoft with 4+ years of progressive experience delivering enterprise solutions for international clients across Europe and Asia. I've evolved from an intern to a key contributor responsible for designing core system components that directly impact product performance and user experience at scale.

My core strength lies in performance engineering and data-intensive systems. I've architected caching layers handling millions of transactional records, designed stored procedures that slashed query times by 30%, and built reporting engines processing 100M+ records with 50%+ speed improvements. I work across the full stack with Java EE, Spring Boot, and Vaadin, but my deepest expertise is in backend architecture and database optimization.

Holding a B.Sc. in Software Technology from FPT University and certifications in Google Project Management and UX Research & Design, I bring both technical depth and a product-oriented mindset. I don't just write code that works — I engineer solutions that scale, perform, and stand the test of production.

Jul 2023 - Present

JAMIX - Enterprise Kitchen Management (Large-scale Production System)

  • Designed and implemented a multi-layered caching architecture for menu pricing data, handling complex hierarchical structures (meals > recipes > ingredients > stock cards) across repeating weekly/monthly cycles — resolving a critical performance bottleneck in the production system
  • Engineered stored procedures with smart invalidation logic that cache prices at the menu-row level and refresh only on cycle transitions, reducing data retrieval latency by 20-30% and eliminating redundant recalculations
  • Architected a high-throughput reporting engine generating Excel/PDF exports for stock events (withdrawal, order, delivery, wastage) across 100M+ records — leveraging indexing strategies and table partitioning to cut report generation time by over 50%
  • Serve as a primary developer for end-to-end feature delivery, from requirements analysis through Jira to production deployment, while maintaining and stabilizing the legacy codebase
