You don't need another freelancer, you need senior capacity that plugs in clean. Documented pull requests, tested releases, handoffs any team can maintain. I build like the next engineer is watching, because they are.

What I build.

Four service lines, owned end to end: from first scope call to documented handoff.

From brief to handoff.

One pipeline, four stages, no surprises. Pick a stage to see exactly what happens there.

01

Discovery & Scoping

Every engagement starts with the actual problem, not the feature list. We map user flows, technical constraints, and success criteria together, then I turn that into a fixed scope with honest estimates — including what I'd cut to hit your deadline.

You get

  • Scope document
  • Estimate + timeline
  • Risk list

cadence: 2–4 days

The first 30 days.

Two ways to run the same brief — a typical agency above the line, me below it. Whatever the project size, the first month looks like this.

  1. Day 1

    agency Discovery call. A proposal is promised for next week.

    me Scope call. You have a fixed quote within 48 hours.

  2. Day 5

    agency Waiting — your project sits in their sales pipeline.

    me Contract signed. A private staging site is already live.

  3. Day 10

    agency Proposal lands. Legal starts reviewing the contract.

    me First demo — real screens, clickable in your browser.

  4. Day 20

    agency Kickoff call. You finally meet the assigned team.

    me Core features work end to end. Weekly demo #3.

  5. Day 30

    agency First sprint planned. Coding starts next month.

    me Demo #4. Small projects ship; big ones are already clickable.

→ same after one month, whatever the size of the project: an agency has a plan. You have a product you can click.

Word gets around.

Questions, answered

The things clients ask before the first call. Pick one.

faq — zsh

➜ ask What does communication look like?

Direct access to me, not a PM. Daily async updates while a sprint runs, a weekly demo, and honest flags the moment something threatens scope or timeline.

➜ ask Do you sign contracts and NDAs?

Yes. NDAs are welcome before we discuss anything sensitive, and every engagement runs on a written scope with fixed deliverables.

➜ ask How does timezone overlap work?

I'm in PKT (UTC+5) with 3-4 hours of overlap with US mornings and full overlap with European hours. Calls are scheduled, not ad hoc.

➜ ask What happens after launch?

Every project ships with a 30-day support window for fixes at no cost. After that, ongoing maintenance is available as a monthly arrangement.

➜ ask Who owns the code?

You do, fully, on final payment. Repos are transferred or were yours from day one. Nothing is held hostage.

➜ ask Do you work white-label under agencies?

Yes, that's a core offering. Your client never has to know I exist. I match your tooling, standups, and delivery conventions.
