About

I build web appswith .NET and Angular.

I’m Jan Kevin Cadampog, or JKC. I’m a full-stack developer in Cebu City, Philippines, and a Software Engineer at OSL International, where I build and maintain web platforms for companies in Japan, including IBC Auto and Jet Logistics. I work on both sides: the .NET APIs and the Angular front ends.

I started in 2021 as a programmer at RD Pawnshop, building .NET MVC applications on SQL Server. From 2023 to 2025 I was an Application System Engineer at Fujitsu, working on HOPE LifeMark-HX, an electronic medical record system for hospitals. I joined OSL International in 2025.

I also built 360°FS and 3QV, the 360° viewer and photo carousel plugins made for Jet Logistics and IBC Auto. In my own time I make the tools on this site: a QR code generator, a searchable library of n8n workflows, and a directory of public APIs.

What I bring

Systems businesses run on

Most of my work is on software that companies use every day: internal tools for a pawnshop chain, a hospital records system, and vehicle export platforms for Japanese clients. I am used to large codebases that already have users, and to changing them carefully.

Production support

At Fujitsu I developed and tested features for each release, handled production support and change requests, and delivered critical work on my own timelines.

Front end to database

.NET and C# on the server, Angular and TypeScript in the browser, SQL Server and MongoDB for data. I can take a feature from the database to the screen without handing it off.
