Infrastructure that stays up, data that stays safe, systems that keep working.
I design, migrate, secure and run the systems businesses depend on: cloud infrastructure, Linux and databases, ERP platforms and the automation around them. 7+ years across enterprise IT: AWS and private cloud, Linux and PostgreSQL, Odoo and Oracle MICROS, incident recovery and AI integrations.

Cloud moves, data migrations, incident recovery, performance work and integrations, across ERP, web and infrastructure. Each one is written up with what was actually done and what it took.

Htet Lin
I am a Senior System Engineer at 7th Computing, and an Oracle Hospitality MICROS consultant, working with companies in Singapore, Thailand and Myanmar. My work covers the whole life of a business system: taking over undocumented servers, planning and executing migrations and cloud moves, tuning PostgreSQL, hardening hosts and responding to security incidents, automating deploys and backups, and building integrations, from ERP platforms such as Odoo to AI tooling.
I prefer changes that are scripted, verified and reversible: every migration gets a replay script, every deploy gets a backup, and every fix gets written down.
How I work
- 01Audit first: read the server, the database and the logs before changing anything.
- 02Backups and a rollback path before every production change.
- 03Automated checks where humans would miss things: path walkers, headless-browser screenshots, restore tests.
- 04Plain-language reporting to the client, including what went wrong.
