Open to work · Colombo, Sri Lanka

Business systems analyst & developer

I build the internal tools businesses run on.

Field-force tracking, inventory, automated reporting and online stores. I work between the people running a process and the system that should be running it for them, and I keep what I build running in production.

About

I'm Ashen, an IT Assistant at Celogen Lanka, a pharmaceutical company in Sri Lanka. Most of my work starts with a spreadsheet someone is tired of maintaining by hand: a field-employee mileage log, a sample inventory, a report that takes half a day to assemble. I turn it into a web app or an Apps Script automation, then stay on to support it.

I hold a BSc (Hons) in Computer Science, Software Engineering from the University of Wolverhampton and an HND in Computing from Pearson, both completed through CINEC Campus. Before Celogen I did IT support at SL Tech and Advertising and taught English at British Way English Academy, a mix that makes me equally comfortable debugging a script and explaining it to someone who's never seen one.
