Call me Francine — Hakuu at work
I ship the backend, then the search setup — APIs, servers, DNS, and Google Search Console. Open to hybrid and remote roles.
01About
Backend first. Then make it findable.
I'm Thu Hà — Francine if that's easier, Hakuu at work. Backend-leaning engineer in Ho Chi Minh City, most recently at C.O Tech AI (Nov 2025 – Aug 2026). I'm open to hybrid and remote roles in backend and technical SEO.
I ship the product — Django, NestJS, PostgreSQL, Docker on a VPS — then I take it live for search: domains, DNS, Search Console, sitemaps, and robots.
Outside work I'm learning Japanese from the basics, slowly and on purpose.

02Technical SEO & infrastructure
The boring layers that make a product show up.
SSH, DNS, Search Console, Nginx, Docker — the same stack I used to take Offspots and ConcorAI live.
DNS & domains
GoDaddy, Cloudflare, and Mắt Bão for registration and DNS records.
Cloudflare
DNS + CDN in front of production apps once the domain is live.
Google Search Console
Property verification, sitemaps, and index coverage after deploy.
Nginx
Reverse proxy on the VPS in front of Docker services.
Docker
Compose stacks with Daphne and systemd on Linux.
03Experience
Two years building products end to end.
- Built end-to-end features for Offspots, a location-based social and voucher platform: Django REST Framework + PostgreSQL APIs, Mapbox Search Box, and React/Next.js UI.
- Built a NestJS microservice for ConcorAI, an AI chatbot integrating the OpenAI ChatGPT API for conversation and image generation, with Free and Plus tiers.
- Designed database models, migrations, RBAC, map-pin tagging, and privacy settings.
- Deployed on a Linux VPS with Docker, Docker Compose, Daphne, and systemd.
- Took products live for search: GoDaddy domains, Cloudflare DNS/CDN, Google Search Console, sitemaps and robots.txt.
- Implemented JWT authentication, CRUD APIs, and a responsive UI.

05Notes
A small journal, not a blog yet.
What I’m studying and shipping right now — short, specific, no filler.
Sep 2026
日本語の基礎
Japanese, from zero
Hiragana, katakana, and a handful of everyday phrases. I’m learning slowly on purpose — same way I learn a new stack: a little every day, no skip-ahead.
2026
From DNS to SERP
SEO in practice
Buy the domain on GoDaddy, park DNS on Cloudflare, verify Search Console, ship sitemap + robots. Code nobody can find is still unfinished.
2026
Locks before features
Spring Boot concurrency
The Mini Banking project is me forcing the boring parts to be correct: optimistic locking, SELECT FOR UPDATE, deadlock order, one transaction.
06Contact
Let’s build
something.
Open to backend and technical SEO roles — hybrid or remote. I can ship the app and the search setup.
