Growth Mindset

Shipped 5+ production-ready products.

Built MVPs from idea to deployment.

Exploring event-driven systems and AI.

Nov 2023

Shipped my first production code

Started building MERN stack apps at Primates. Realized quickly — features are easy, systems breaking at scale is the real problem.

Sept 2024

Got promoted. Went deep on databases.

Client hired me directly at Tensys. Spent the year obsessed with one problem: why is everything slow? Cut load times 3s → 800ms. That changed how I think about code.

Nov 2025

Built my own thing. ClapOS.

Full ownership of a film industry SaaS from zero. Microservices, Kafka, 10 modules live. Proved I could architect systems, not just write features.

Present

Looking for the next hard problem

Open to full-time roles at startups building at scale. Parallel: learning distributed systems, ideating the next MVP. Always shipping, always growing.

What I Solve For

SYSTEMS THAT HANDLE REAL TRAFFIC

Users bounce on slow pages. I cut load times 3s → 800ms. They stayed. That's the difference.

Proven At

5+ hospital clients, 100+ appointments/day without breaking

ARCHITECTURE THAT SCALES WITHOUT CHAOS

Event-driven systems aren't just buzzwords. Kafka handles thousands of events without coupling. When one service breaks, others keep working.

Proven At

ClapOS — 10+ modules talking through events, zero data loss

PRODUCTS THAT WORK GLOBALLY

RTL languages, currency conversion, timezone logic — complex. But users in Dubai don't care about complexity. They care that it works.

Proven At

PlusUAE — 5 languages, RTL, CRM-integrated, in production daily

SHIP FAST WITHOUT BREAKING THINGS

I don't hand off half-finished features. Every product I shipped handles real users on day one. That's the discipline.

Proven At

5+ products from zero to production. 2-3 month cycles. Still running.
