Hi, I'm Nathakamon.
Software Developer

I build enterprise software — specialising in ServiceNow platform development, backed by full-stack and .NET experience.

About

I help enterprises ship reliable software, faster.

A ServiceNow developer (CSA) and full-stack engineer with 5+ years — turning business requirements into automated, well-documented systems that cut manual work and deliver on time.

I'm Nathakamon, a software developer based in Bangkok, Thailand. My work centres on enterprise ServiceNow development, backed by a full-stack and .NET background — two worlds that reward the same thing: clarity.

I started in IT support and data analysis, moved into full-stack .NET development, then specialised in enterprise ServiceNow — delivering ITSM, CSM and SecOps solutions, custom widgets and workflows for large organisations. I care about the parts users never see — the security model, the automation, the documentation — because that's what makes the parts they do see feel effortless.

With a Computer Engineering degree and 5+ years across industries, I'm happiest turning messy business requirements into reliable, well-documented systems — and quietly automating the busywork out of a team's day.

Core values

Craft over shortcuts

Every detail matters. I sweat the micro-interactions, the empty states, and the code nobody sees.

Problem solver first

I start from the business outcome and work backwards to the simplest architecture that gets there.

Reliability by default

Typed, tested, observable systems. I build things that hold up under real enterprise load.

Performance obsessed

Fast is a feature. I optimise for Core Web Vitals, bundle size, and time-to-value.

Skills

A toolkit built for shipping real products.

Depth where it counts, breadth where it helps — the tools and platforms I reach for in production.
