I'm a software engineer with over 9 years of experience, currently a Engineering Manager at GearVN — one of Vietnam's largest technology retailers. My work lives in the things that run in the background: queues, webhooks, data sync across systems, and the infrastructure that keeps it all stable.
Lately my focus has shifted toward AI infrastructure — I'm building an agentic data platform (managed Postgres, data pipelines, DAG execution) and the operations core that runs the business, on top of a modern Go microservices platform (Clean Architecture + CQRS) with Next.js frontends. Before that I designed and built the order management system, the fulfillment platform and a multi-channel notification hub that keep GearVN's commerce running.
I'm comfortable at both ends — from Go and Node.js on the backend to React and Next.js on the frontend — but what I do best is turning vague business requirements into systems that run, that can be measured, and that scale.
System architecture · DevOps · Project management
Administer the source code and the entire IT infrastructure; design project architecture and CI/CD pipelines with Jenkins & ArgoCD; initialize and operate GearVN's Kubernetes cluster. Lead the Order, Fulfillment, ERP, BI, Notification and Survey projects — working directly with the Board of Directors to design business workflows.
Distributed crawler · Computer Vision
Designed the architecture and communication models for two service groups — management and agent: orchestrating and distributing execution requests to data-scraping agents. Built a CAPTCHA-solving solution using computer vision, and an app that aggregates flight schedules from the Internet.
University of Information Technology
Major in Computer Science. Faculty academic incentive scholarship for two consecutive years (2013–2015).
Architect · Backend & Platform
An agentic, AI-first platform for managed Postgres databases, data pipelines and DAG execution. Backend-agnostic by design — local, Docker, Kubernetes, Nomad or cloud workers all sit behind one control-plane API. Go control plane and workers, Next.js UI.
Open-source contributor
A multi-agent AI gateway rebuilt in Go — agent teams, delegation and orchestration in a single binary, with multi-tenant isolation and 11+ LLM providers (3.4k★). My contributions include the agent-teams task system (workspaces, follow-up reminders, auto-recovery), a Claude CLI provider with MCP bridge, multi-engine browser automation (pool, stealth, proxy, live view), and security hardening against prompt injection.
Tech Lead · Backend Architecture
A suite of Go microservices in Clean Architecture + CQRS — authentication (JWT/Argon2), PIM, CRM & Marketing, Core Ops — with Next.js frontends. The backbone that internal teams build on.
Architect · Internal Platform
An internal framework that lets business users build and run parts of the system themselves — from POC through to live operation — configuring workflows and logic without deep developer involvement. It cuts the path from idea to shipped feature and frees engineers for the harder problems.
Fullstack Developer · Architecture & Database
GearVN's core order management, tracking and processing system. Integrated with WMS (NhanhVN), ERP (SAP) and many shipping partners; built a webhook gateway on AWS along with a post-check service that syncs order, payment and inventory status.
Cut 80% off processing time · handled 11× more orders per day
Project Leader · Back-end Developer
A pick–pack platform that issues delivery notes to shipping partners, with real-time inventory management logic. From requirements gathering and architecture design to building APIs and event flows over Kafka.
Project Owner · Back-end Developer
A multi-channel hub for sending notifications to customers and internal users: template configuration, provider integrations (South Telecom, FPT SMS Brandname), and a model that lets third parties connect and reuse the messaging flows.
Project Manager · Fullstack Developer
Led the BI project from report collection, ETL and data warehouse to visualization (QuickSight, Tableau). On the ERP project, built a custom core integrating with SAP S/4HANA and worked directly with the Board of Directors to design workflows.
