White-label engineering partner for agencies
Your agency sells it.
We engineer it.
The SyncFlow is the white-label engineering partner for agencies when client requirements outgrow their team, their no-code stack, or their AI-generated prototype.
- Signed first
- NDA and non-circumvention
- Risk-free
- The first milestone
- Yours
- Code, IP and client
- UTC+5
- Daily overlap, your hours
The month it always happens
You closed the project. Now you need engineers you don't have.
Say no
You lose the build, and usually the retainer attached to the client who asked for it.
Say yes anyway
You take work your team cannot resource, and the deadline becomes someone else’s problem to explain.
Hire for it
Six to twelve weeks of recruitment, then a salary that outlives the project by a year.
There is a fourth option, and your client never sees it.
Capabilities
Six things agencies hand over. Nothing they don't.
Each one is a defined engagement with a scope, milestones and a handover, not an open-ended retainer.

Process
Four steps. No surprises in any of them.
Low-risk at the start, predictable in the middle, clean at the end.
- I
Fit call
Twenty minutes on what you sold, when it is due, and the stack it has to live in. If it is a bad fit we say so on that call.
- II
Pilot milestone
One small paid deliverable so you can judge the code and the communication before committing to a full build.
- III
Milestone delivery
Work ships in scoped milestones inside your tools, with written updates and a Loom walkthrough at each one.
- IV
White-label handoff
You own the code, the IP and the client relationship. Documentation, handover notes, and no dependency on us.
Coverage
Your business day, already covered.
We work monday to saturday, 08:00 to 02:00 UTC+5, a full working day of overlap with North America, the UK and the EU, and the afternoon in Sydney. Replies land inside 3 hours during the window.

Founding engineer on a multi-agent AI platform. Architecture, calendar integrations and automated content scheduling, shipped solo.
- 500 hrs
- Scope
Real-time trading infrastructure built to hold its latency budget under volatile market load.
- Full build
- Scope
Automated reminders and Stripe subscriptions for a multi-tenant salon booking platform.

Every one live, or handed over complete.
No exceptions, no disputes, no refunds.
Committed, not averaged after the fact.
We have never contacted a partner's client.
Stack
Whatever you already run on. Probably this.
Shipped in production, not read about. If your client runs on something else, say so on the call and we will tell you honestly whether it is work we should take.

Protection
Your client stays your client. In writing.
Six things that exist before the first line of code, rather than getting negotiated after something goes wrong.
- NDA
- Signed before any scoping detail is exchanged. Your client names and commercial terms stay yours.
- Non-circumvention
- A written commitment never to approach, solicit or accept work from your client. Signed up front.
- IP assignment
- Code, IP and deployment configuration transfer to your agency or your client on payment.
- Milestone payments
- Each milestone scoped and priced before it starts, invoiced on delivery. Never a full project of exposure.
- Your repository, day one
- Work is pushed continuously to a repo you control. You always hold current, working code.
- No lock-in
- End the engagement at the close of any milestone. No notice penalty, no retainer commitment.
Engagements
Three ways to work together. Start with the smallest.
Pricing is quoted per scope after the call, because a client portal and a Webflow migration are not the same job. You get a scoped quote within 24 hours.
Pilot milestone
The cheapest way to find out whether this works.
Typically 5 business days
- One defined, scoped deliverable
- Real code in your repository, not a proposal
- Loom walkthrough at delivery
- Risk-free: if it is not right, you do not pay
- No obligation to continue
Project build
A scoped build, delivered in milestones under your brand.
Typically 4 to 16 weeks
- Full scope agreed before the first milestone
- Milestone pricing fixed in advance, invoiced on delivery
- Daily overlap with your business hours
- Written updates plus a Loom at every milestone
- Work inside your Slack, GitHub and project board
- Documentation and handover at the end
- NDA, non-circumvention and IP assignment signed up front
Engineering retainer
A standing engineering seat on your team, month to month.
Monthly, cancel at any month end
- A reserved block of senior hours each month
- Maintenance, fixes and small features without re-scoping each one
- Priority on your queue ahead of new projects
- Attends your standups if you want them attended
- Roll work across multiple client projects
- Same NDA and non-circumvention terms
- No notice penalty when you stop
All three include NDA, non-circumvention, IP assignment and milestone payment terms. Get a scoped quote in 24 hours.
The only guarantee we make
First milestone. Free if it's wrong.
If the first deliverable of a new engagement is not what you wanted, you do not pay for it, and you keep the code anyway. No clause underneath, no discount instead, no second attempt you are obliged to accept.
Objections
The questions you're actually asking.
Subcontracting a build is a trust decision before it is a technical one.
No. Delivery is fully white-label. An NDA and a non-circumvention agreement are signed before scoping, we never contact your client, and everything reaches them through you. Work happens in your repositories, under your brand, in your voice.
The SyncFlow is founder-led. Safi leads engineering on every project from scoping to handover and personally reviews and signs off everything that ships, so nothing reaches you without his oversight. If an engagement needs more hands, engineers on the team execute specific pieces under his direct supervision, always disclosed upfront, never swapped in without you being told. That oversight is deliberate, not a constraint we are working around. Bus factor is handled structurally rather than by headcount: your code lives in your repository from day one, work is pushed continuously rather than delivered in one drop at the end, and documentation is written as we go. You can stop at any milestone holding everything a different developer would need to continue the work elsewhere.
You are never exposed to a whole project at once. Code is pushed continuously to a repository you own, so you always hold current work. Payment is by milestone, each scoped and priced before it starts. You can stop at the end of any milestone with no notice penalty, and the first milestone is risk-free.
We work monday to saturday, 08:00 to 02:00 UTC+5. That covers a full business day in New York, Toronto, London and Amsterdam, and the afternoon in Sydney. Inside that window we reply within 3 hours. Outside it you get written updates and a Loom at every milestone.
We are not going to bury it. The studio runs from Islamabad, Pakistan, on your business hours. A five-star rating on every completed engagement is the evidence that distance has not been the problem. Unpredictability is the actual risk, and that is a process question rather than a map one.
Agency-appropriate contracts, a delivery process built around how agencies ship, and continuity: the same engineer who learned your standards on the first project is the one on the next. Not a transaction that restarts from zero every time.
Quoted per scope after a 20-minute call, because a client portal and a Webflow migration are not the same job. You get a scoped quote within 24 hours of that call, and the first milestone is risk-free either way.
Who leads the work
One name on every engagement.
The SyncFlow is led by Muhammad Safiullah Khan, a full-stack engineer working from Islamabad, Pakistan. He scopes every engagement, owns the architecture and personally reviews and signs off every milestone before it reaches you. There is no account manager between you and the engineer accountable for your client’s product, and no work ships without him having looked at it. When an engagement needs more hands, engineers on the team execute under his direct supervision, disclosed upfront and never swapped in without you knowing.
That oversight is a deliberate standard rather than a stage the studio will grow out of. It is why scope survives, why standards hold across projects, and why the second engagement is faster than the first.
