Backend Dev & AI Integration
I build systems
that actually scale.
7 years of production backend work — APIs, databases, distributed systems.
In early 2025, I left my job to build on my own terms.
Now helping teams integrate AI into their workflows — without the hype.
Based in Ho Chi Minh City.
What I do
Services
AI Integration & Automation
Connect your tools. Automate the repetitive parts. Build pipelines that run while you sleep — Claude API, OpenAI, n8n, custom webhook flows.
Upwork — $20/hr+
Fast, Focused Websites
Content-first sites built on Astro + Cloudflare Pages. Sub-second loads, zero runtime overhead, easy to maintain. This portfolio is built on the same stack.
From 5M VND / project
Backend Architecture & APIs
API design, database optimization, AWS infrastructure. I've handled systems at 15M+ record scale. I know where things break before they do.

36 hrs → 2 hrs
Matching System Optimization
A nightly matching job that took 36 hours was breaking SLAs and blocking downstream reports. Profiled the query planner, rewrote the core algorithm, and added targeted indexes. Job now completes in under 2 hours — no infrastructure changes required.
3 hrs → 5 min
Automated Incident Response
On-call engineers were spending 3+ hours per incident manually correlating logs across services. Built an automated triage pipeline that detects anomalies, traces root cause across distributed logs, and fires a structured Slack alert. Mean time to resolution dropped by 97%.
0 → production
Transport Management System
Greenfield TMS for a logistics client — designed the data model, built the REST API, and delivered the frontend. Handles order lifecycle, driver assignment, and real-time status updates. Deployed on AWS with MongoDB for flexible schema evolution.
Manual → automated
AI-Powered Content Pipeline
Content team was manually drafting, scheduling, and publishing across three platforms — 4–5 hours per week. Built an n8n pipeline that ingests raw notes, runs them through Claude API for drafting and formatting, then queues for review and auto-publishes. Team now spends 30 minutes reviewing instead of writing.
Background
About
Backend developer based in Ho Chi Minh City with 7 years of production experience — APIs, distributed systems, data pipelines at scale. Currently working independently on AI integration and backend projects.
I work best on problems with real constraints: performance targets, reliability requirements, actual deadlines. If you have a system that needs to be faster, smarter, or more automated — that's where I fit.
