Hello There. I'm
Sasitha Madushanka
Technical Lead with 10+ years crafting enterprise applications on AWS. I transform complex business challenges into elegant, performant software.
About me
I'm a problem solver at heart who thrives on seeing code transform into solutions that real users love.
With over 10 years of experience as a Technical Lead, I specialize in building scalable cloud solutions that deliver exceptional value. My approach is simple: understand deeply, build thoughtfully, and deliver reliably.
I believe the best software comes from teams that combine technical excellence with genuine collaboration. That's why I'm passionate about mentoring developers – guiding them to discover their own strengths while building systems that matter. Through practices like TDD/BDD, I've helped teams achieve 90% code coverage while delivering features that truly capture user needs.
My proudest achievement? Leading the Trailer Hire project where we delivered a solution for a fraction of the initial estimated cost while dramatically reducing AWS maintenance expenses. This exemplifies my philosophy: elegant solutions don't have to be complicated.
