I build secure, scalable web and mobile applications. With a deep interest in how systems are constructed — and how they can be hardened — I approach every project with both a developer's and an engineer's mindset.

ABOUT

Building things
that matter.

I'm a full-stack developer specializing in crafting modern web and mobile applications. My approach combines clean engineering with a genuine obsession for how software systems work under the hood.

Beyond shipping products, I'm deeply invested in the security and resilience side of software — understanding attack surfaces, how applications can be hardened, and writing code that holds up under real-world conditions.

I've worked with early-stage startups and growing businesses, helping them build scalable infrastructure and user-centric products from the ground up.
