WHY FOUNDERS COME TO ME

Development is broken.You already know this.
THE COST

"It shouldn't cost this much."

You paid $8,000 for a feature that took six weeks and still has bugs. Every change becomes a negotiation. Every invoice is a surprise.

Agency Avg: $150–250/hr
THE TIMELINE

"Two weeks" means two months.

You've heard "it's almost done" so many times it stopped meaning anything. Your competitors shipped three features while your backlog didn't move.

Avg Delay: 2.4× the estimate
THE ACCOUNTABILITY

Nobody actually owns it.

The frontend blames the backend. The PM blames the spec. You're paying four people and nobody is responsible. When something breaks, you get excuses—not fixes.

0 people with full ownership

THE ADVANTAGE

I'm not a team replacement.I'm your unfair advantage.

Six years building real products. Fluent in AI tools that make me 3–4× faster than a solo developer working the old way. When something breaks, I fix it. No tickets. No hand-offs. No blame chains.

I

You get the actual person.

When you message me, I answer. When something breaks, I'm the one who fixes it — not a junior who's never seen the codebase. I don't have a support queue. I have clients, and I treat you like one.

×4

I use power tools.

AI handles the repetitive 60% of development so I can focus entirely on the 40% that requires real engineering judgment. You get the output of a small team at the cost of one person.

Your project actually moves.

No meetings about meetings. No wondering what's happening. Weekly progress updates — not because I have to, but because I know that's what trust looks like. You tell me what you need. I build it. You see it.

HOW IT WORKS

Simple. No drama.

Three steps. That's genuinely all it is. No agency bloat.

01

We Talk

30 min, free

You walk me through what you're building. I'll tell you honestly if I can help, what it would cost, and the timeline. No pitch deck, just a straight conversation.

02

We Start Small

One defined project

We pick a specific scope with an agreed price. You see exactly how I work before committing to anything ongoing. If you aren't happy, you walk away with a working product.

03

We Keep Going

Ongoing retainer

Once you've seen the value, most clients move to a monthly retainer. Costs stay predictable, deadlines get hit, and problems get solved before they surface.

IS THIS RIGHT FOR YOU?

I'm honest aboutwho I can help.

This works really well for some. For others, I'm genuinely not the right choice. Here's the breakdown.

You'll love this if you...

  • Are running a business that needs real development but can't justify a full team
  • Are tired of agencies that overpromise and underdeliver
  • Need someone who owns problems, not just closes tickets
  • Know that cheap, fast, and good usually means picking two

This won't work if you...

  • Need 10+ developers working full-time in a physical office
  • Change your core requirements every few days
  • Need someone in 8 hours of meetings per week
  • Are not willing to stay involved and provide feedback

LET ME BE STRAIGHT WITH YOU

A few honest thingsmost devs won't say.
01
"I'm not a miracle worker."

I can't compress three months of work into one week. But I can do in two weeks what most developers take six. It's not magic — it's focus.

02
"AI helps. But I do the work."

Tools make me significantly faster at the repetitive parts, but they don't replace six years of product judgment and architecture experience.

03
"I take 3–5 clients. Not 50."

I'm not scaling a freelance empire. I take a small number of clients and actually focus on them. When I reach capacity, I'll tell you directly.

04
"Your involvement matters."

The projects that go well are the ones where we both show up. I build it. You own it. We're partners, not strangers.

COMMON QUESTIONS

Questions peoplealways ask me.

If something isn't covered here, ask it on the call.

Honestly, this is a fair concern. I've been doing this for six years and it hasn't been an issue — I don't take on more than I can handle, which means I always have margin for the unexpected.

That said, I'm transparent with clients about my schedule. If something comes up, you'll hear from me immediately — not after a week of silence. I'd rather have an uncomfortable conversation early than let a project slip without explanation.

I work with US-based clients specifically, so my working hours are structured around US time zones (ET/CT primarily). You won't be waiting a day for a response because of a timezone gap. Same-day responses are the norm, not the exception.

Yes — completely. Everything I build for you is yours. You get full source code, full ownership, no licensing fees, no strings attached. I transfer all repositories to your accounts when the project completes. This is non-negotiable and I'm happy to put it in the contract in plain language.

We talk about it before I go over — not after. If a project is tracking larger than the 50-hour retainer covers, I'll flag it early, explain what's driving it, and we agree on how to handle it together. No surprise invoices. Ever.

Yes — that's actually one of the main reasons clients move to a monthly retainer. Shipping is the beginning, not the end. Bugs happen. Requirements evolve. Infrastructure needs monitoring. I offer ongoing maintenance as part of retainer engagements, and as a separate arrangement for project-based clients.

Scope changes happen on every project — that's not a problem, it's just reality. The process is: we identify the change, I estimate the impact on timeline and cost, we decide together whether to include it now or phase it later. Nothing gets added silently. Nothing gets billed without agreement. The spec is a living document, not a contract to hide behind.

A US-based agency at $150–250/hr will cost you $24,000–$40,000 for the same project I'd build in a fraction of that. A cheaper offshore team often means miscommunication, timezone friction, and code you can't maintain later.

What I offer is the middle path: US-aligned working hours, direct communication, six years of real product experience, and pricing that doesn't require a funding round. That's the actual value proposition — not that I'm the cheapest, but that you get genuine quality without the agency overhead.

READY?

Let's buildsomething real.

30 minutes. No pitch. No pressure. Just an honest conversation about your project and whether I can actually help.
