Full Stack iOS & Web Developer
Hi, I'm
Mesut As
I bring your ideas to life on the App Store as an independent iOS developer, while crafting fast, custom-coded, and performance-oriented websites tailored for products, brands, and businesses.
About
I'm an iOS engineer and founder of TechAs.co, building indie apps end to end, from UI/UX and SwiftUI architecture to Firebase, RevenueCat, and App Store launch. I also design and deliver custom-coded websites, from landing pages and portfolios to multi-page product sites, using modern front-end stacks with a focus on performance, accessibility, and maintainable code. My portfolio includes Focus Next, Titan Fit, English Pro, and Istanbul Guide across productivity, health, education, and lifestyle. iPreggy was a client delivery: end-to-end iOS development for a corporate client, from concept to App Store release. I also founded DevCircleUp, a community where developers share projects and grow together, and I continue to take on freelance iOS and web projects alongside my own releases.
