Who I am.

I’m a senior mobile and web developer with a product mindset. I specialise in building high-quality apps from zero to launch — not just writing code, but shaping ideas into real, usable products. I’ve worked across startups, scale-ups, and established teams, helping turn vague concepts into polished, scalable software that people actually use.

What I Do.

I focus on fundamentals first: clear thinking, simple architecture, and clean execution. I care deeply about maintainability, performance, and user experience — because good software should be easy to evolve, not fragile. I prefer small, deliberate iterations over rushed features, and I build systems that are designed to last.

My technical expertise allow me to launch products across all platforms. This has vastly increased my clients profitability as we set up web to app flows that mean no 15% (or even 30% sometimes) app store fees are taken.

What I believe truly sets me apart is my obsession on the customer experience. I regularly engage with customers of my products, setting up whatsapp groups, feedback channels and allow them to drive the product. This is something I learnt working with ex-Founders of Monzo.

Outside Of Work.

Outside of work, you'll usually find me on the mats, practicing Brazilian Jiu-Jitsu. I'm a brown belt and help out teaching some classes at my local gym.

More recently I've also caught the padel itch, with a ranking of 3.2, so if you ever fancy a match, hit me up! I also enjoy wakesurfing, where I spend most time trying not to drown.

Aside from sports, I am fascinated by the idea of making money with math. What started out with exploring algorithmic trading, options trading, and quantitive finance, led me to poker, blackjack and various alternative ways to make money with math.

Let's build your next app together.

I specialize in building high-quality mobile and web applications for brands of all sizes. From initial concept to app store launch, I'll help bring your vision to life.
