About me
Hi, I'm Kevin Sajan
Full-stack developer and data scientist in training · Toronto, Ontario, Canada
I build software that solves real problems. By day I'm a software developer at MacLean Engineering, where I build machine HMIs, the interfaces operators use to monitor and run heavy equipment. Over the years there I've also built full-stack web apps, REST APIs, Python desktop tools and 3D point cloud visualizations, and deployed them on Microsoft Azure.
Before that I worked in financial advisory and tax at Deloitte, automating document workflows and digging into invoices and financial data. That mix of code and business is why I care about results, not just features.
I'm currently completing a Master of Data Science at the University of Pittsburgh, focused on data modelling, warehousing and AI in data management. Through KIS Studios I take on client projects of every shape: websites, apps, stores, games, data work and whatever else is holding your business back online.
