Hi! I'm Zack.
I'm a full stack developer and life-long learner with a deep passion for problem solving and tech. With a rich background in the music industry, working alongside artists and music labels, I've transitioned my creative mind and audio engineering skills into the world of software development. When I'm not at my computer, I like to spend my time learning Japanese, keeping fit and producing music.

About
🌱 How It Started
My journey into software began with late nights on Codecademy, the guidance of a patient mentor, and hands-on learning through freelance gigs. Things took off at Sounds Like Soma, a Philadelphia-based recording studio, where I managed the studio’s website and IT infrastructure. There, I had the unique opportunity to collaborate with global recording artists and record labels—designing promotional landing pages and crafting dynamic electronic press kits that helped bring their stories to life.
👨💻 Where I Am Now
Most recently, I served as the lead full-stack web and mobile developer at a Philadelphia-based PR agency. The role challenged me to constantly explore new technologies—from real-time data processing and IoT integrations to modern frameworks like React Native and Next.js. It pushed me to grow not just as a developer, but as a creative problem-solver and collaborator.
🔍 What I'm Looking For
In my next chapter, I'm looking to join a team of curious, motivated professionals building software that has a real-world impact. I thrive in environments that value continuous learning, shared knowledge, and thoughtful engineering. If you're building something meaningful—and need someone who can turn bold ideas into functional, scalable products—I'd love to connect.
