Mert & Kadir · Built & Kept Alive

Two senior builders.
Software that keeps working.

You know the risk: the one person who holds your whole system in their head goes quiet — and everything waits on them.

Two people. 25+ years. You contract with both of us, and both of us are who build, ship, and keep your software alive.

  • No subcontractors
  • No rotating teams
  • No handoff

You hand us a goal, not a ticket.

You don’t hand us tickets. You hand us a goal, and we take it from zero to shipped ourselves: product, engineering, the decisions, the code.

We don’t just advise, and we don’t just code. We take responsibility for the software becoming real, and staying real.

  • Two on every hard call

    Architecture, build-vs-buy, the scary migration — decided by two senior people who both know your system, not one person guessing alone.

  • No single point of failure

    Knowledge lives in two heads. One of us is out, the work keeps moving and nothing walks out the door.

  • More range

    Two senior skill sets cover more ground than any one person: product, infrastructure, data — whatever your stack needs.

Who this is for

  • One person holds the whole system. A single developer or CTO knows how it all fits together, and everything waits on them.
  • You bought senior names and got juniors. Dev shops sell you senior names, then staff the work with juniors you never meet. We’re the opposite.
  • You’re weighing a full-time hire. Two senior people, without two salaries, two sets of benefits, or the gap when someone leaves.
  • You have live software that needs keeping healthy. Upkeep, fixes, targeted improvements — not a rebuild.
  • The roadmap has stalled. One priority at a time, taken from zero to shipped.
  • There is no product or engineering function yet. Run us as your whole product and engineering team.

Not for a contracted 24/7 on-call guarantee — that is a separate arrangement. Not for staff augmentation that takes tickets.

How we work

  • Goals, not tickets. You set the order and can reprioritize whenever you want. We own the execution.
  • One priority at a time. That’s the feature, not a limit.
  • Both of us, on everything. No subcontractors, no rotating teams, no handoff.
  • A fixed daily check-in each weekday, in your timezone — we adapt to it. Plus one weekly call.
  • Scheduled, not a pager. Everything outside the weekly call is in writing: Slack, email, comments on the work.
  • A live-product problem jumps the queue and gets handled the same business day — not stuck waiting on one person.

What we believe

It has to work on Monday, and still work next year. That’s the whole point.
  • Durability over delivery. Shipping is half the job. Built and kept alive is the other half.
  • The people you hire are the people who do the work. No junior handoff, no context dropped on the floor.
  • Knowledge belongs in two heads. Redundancy is the point, not a side effect.
  • Honesty, including about limits. Where a limit applies, we say it out loud rather than smoothing it over.
  • Real over demo. Autonomous and assistive AI wired into real workflows, not demos.
  • Craft that outlasts the cycle. We’ve been shipping since 1999, through every era of the web — from the first dynamic sites to today’s AI agents. The decade changes. What we do with it doesn’t: build it properly, ship it, keep it alive.

What we’ve shipped

  • AI agents & copilots Autonomous and assistive AI wired into real workflows, not demos.
  • Coaching & learning Platforms that track client progress and prove the results at scale.
  • Real-time comms WebRTC calls, voice messaging, call-centre queues, support ticketing.
  • Commerce & payments Bespoke e-commerce, failed-payment winback, group reservations, referral rewards.
  • Email infrastructure Deliverability, reputation, and engagement you can actually measure.
  • Platform & SDKs The quiet plumbing that other products are built to run on every day.

Whatever your stack needs next, two of us have already shipped something like it — and kept it alive.

Tell us the goal.

We’ll take it from zero to shipped — and keep it alive.
