Senior Frontend Developer - FPT Software

(2026-03)

Currently working on Healerz, a digital healthcare marketplace that connects patients, providers, and organizations through structured workflows and generative-AI features.

• Built and maintained marketplace modules using React.js, TypeScript, React Query, and Framer Motion for a healthcare platform
• Translated complex healthcare rules and multi-state API flows into intuitive, developer-friendly UI patterns
• Aligned payload contracts, edge cases, and failure states with .NET engineers pre-integration to eliminate late-stage risk

Senior Frontend Developer - FireGroup

(2022-02 - 2025-12)

Worked across Zopi, AliHunter, and BD Center. The products were different, but the frontend problems repeated in familiar ways: complex user flows, large datasets, shared UI foundations, rendering performance, and API contracts that needed to be discussed early.

• Drove features end-to-end — estimation, architecture decisions, implementation, testing, and post-release fixes — across key revenue products
• Improved rendering and interaction performance using Web Vitals, profiling, and before/after benchmarks rather than guesswork
• Contributed to Zopi earning "Built for Shopify" certification and two "Product of the Year" awards; mentored interns through production work

Frontend Engineer - DigiNet Corporation

(2019-04 - 2022-01)

Worked on enterprise products where most frontend complexity came from business rules, permissions, forms, and large operational datasets rather than visual effects.

• Delivered Time & Attendance, Payroll, Leave, and Employee Profile modules; kept large data tables responsive across thousands of records
• Encoded complex business rules into maintainable forms, tables, and workflows with shared component libraries to reduce duplication
• Contributed React Native features for selected mobile workflows alongside core web delivery

Backend Developer - Ebizworld

(2017-06 - 2019-04)

Early career role on business management systems for customer management, orders, inventory, and reporting. I keep this section brief because my current direction is frontend engineering, but the experience still helps me understand APIs, database queries, and business logic better.

• Built REST APIs, MySQL queries, and responsive Blade/Bootstrap interfaces with PHP/Laravel; supported production releases from requirements through deployment
