Marek Lesko — Software Engineering Team Lead

About

I have 25 years of programming experience, starting with Turbo Pascal and Visual Basic 6, working through .NET, Xamarin, .NET Core, TypeScript and Angular. I started coding for fun — building websites and utilities for friends and family — and eventually turned it into a career.

Today I lead software engineering teams delivering business intelligence reporting tools at BigHand, bridging technical decision-making with team execution in an agile environment. I'm passionate about building great products and great teams.
