For founders

Are you a founder, and...

01

Brilliant idea, but no team to build it right?

02

Ghosted mid-project or stuck with costly code?

03

MVP works, until real users show up?

I turn rough ideas, broken builds, and stalled MVPs into production-ready software.

What I offer

Work with me and you'll have...

A platform built around how your business actually runs, not a generic template patched to fit

A codebase that won't need a full rebuild six months from now

Data that tells you what's happening in your product, in real time

An interface your users don't need a manual for

One engineer who owns the full thing: architecture, code, decisions, delivery

Something you can hand off, scale, or sell because it was built properly from day one

Your runway is bleeding on the wrong build

Ghosted freelancers. Stalled MVPs. Code that breaks the first time real users show up. Most founders don't lose on the idea — they lose months and capital on weak ownership.

6–18 monthsAverage time founders lose rewriting a product that was never architected to scale.
50–80%Startup software projects fail or stall when there's no senior owner from day one.
Proof under pressureSenior ownership is how founders avoid expensive rebuilds.
Millions

Scaled real-time systems

Took a system stuck at 1,000 concurrent users to support millions with targeted architecture and performance work.

100k+ rps

Built for heavy traffic

Architected large-dataset applications for high throughput and low-latency performance under serious load.

Gov scale

Delivered in high-stakes teams

Contributed core production features to a Dubai Government application where reliability mattered.

Days

Unblocked stalled products

Diagnosed critical blockers, fixed root causes, and helped products reach go-live on compressed timelines.

Shipped

Production-first execution

Released multiple stable, scalable products to production without letting quality collapse under deadline pressure.

UX

Built experiences users trust

Designed and delivered smooth, intuitive interfaces backed by performance that feels fast in real use.

You don't need more developers. You need one senior engineer who owns architecture, delivery, and the decisions that keep your product from becoming a rewrite.

That's the pain I remove for founders.
Ready when the work matters

Have an important product to build or a senior role to fill?

Book a strategy call. I'll help you turn messy requirements, stalled systems, or high-pressure delivery into a clear path to production.

Main pitch

Software should ship.
When it doesn't, that's where I come in.

From messy codebases to half-built AI features to systems that buckle under load I've seen the patterns. I work directly with engineering teams to unblock delivery, make the right architecture calls, and get production-ready products out the door.

AI Engineering

You built the AI feature. It just doesn't work right.

Most LLM integrations fail quietly: hallucinations slip through, RAG pipelines return garbage, agents loop or break under load. I come in after the hype, find what's actually wrong, and rebuild it to be reliable, fast, and production-grade.

Product Development

The idea is clear in your head. The path to production isn't.

I've taken rough napkin ideas to deployed products more times than I can count. I handle the full build architecture, APIs, auth, database design, cloud setup, so you're not stitching together freelancers or guessing at decisions that will cost you later.

Scalability

Your app works fine. Until it doesn't.

Traffic spikes, slow queries, jobs that back up under load these aren't random. They're predictable, and they're fixable before they become incidents. I tune the systems that are already there and redesign the ones that won't hold.

Security

Security debt is invisible right up until it isn't.

Most teams know the gaps are there. They ship anyway. I work through auth flows, API exposure, authorization logic, and OWASP coverage not as a compliance checkbox, but as the thing that lets you actually trust what you're deploying.

Why Hire me?

Senior & founding full-stack engineer with 10+ years shipping production SaaS, AI-powered systems, and high-scale platforms. I architect, build, and ship the way a founding engineer does.

What you really get
01

I do not just write tickets. I own outcomes, architecture, delivery, and the product experience.

02

I can step into messy systems, find the real bottleneck, and ship production fixes fast.

03

I bring founder-level judgment across system design, user experience, reliability, and speed.

04

Recruiters get a senior engineer who can talk to product, lead delivery, and still write the hard code.
