I build engineering functions from zero — infrastructure, tooling, environments and process — and lead the team that ships on top of them. # scroll down, or type help in the shell at the bottom

I started out writing code. For several years I was a web developer, most recently as a Senior Software Engineer at Micepad, building event technology products.
In 2024 I moved into project management at Talentbank as the company's first IT PM. There was no engineering setup to inherit — no cloud infrastructure, no deployment pipeline, no development environment, no process. I built it from scratch, and today I lead a small team of designers and developers shipping products end to end.
Email was costing us five figures in RM for a single large-scale event, and only 20–30% of those messages reached the inbox. I migrated us to AWS SES with proper sender authentication (SPF, DKIM, DMARC): annual email spend now runs under RM2,000, with delivery above 95%.

Our events were still checking candidates in by hand — long queues, and staff pulled off other work to run clipboards at the door. Nobody asked me to fix it, so I built a QR code check-in system. Measured at peak arrival across several large events: under five minutes, consistently.
"Going from zero is less about technical difficulty than about making irreversible decisions with very little information, on a small budget, while requirements are still moving."
Coming from an engineering background helps — I can size up a technical trade-off myself instead of relaying it between stakeholders and the team.

Moved transactional and campaign email from a third-party platform to AWS SES. Inbox delivery rose from 20–30% to over 95%; annual spend fell from five figures in RM to under RM2,000, and a peak event month runs only about RM100 above a normal one.
Built on my own initiative to replace paper check-in at large recruitment events, which had pulled staff off other duties. Verified average peak-time wait under five minutes across multiple events.
Set up the company's cloud infrastructure, CI/CD pipelines and development environments, none of which existed before.
