01 Fractional CTO Sprint
Technical direction for founders who are building the product themselves.
A bounded sprint with Rheeshaalaen Sabapathy. You leave with the decisions, the architecture, and a sequenced build plan. Implementation or a part-time retainer starts only if you want it.
02 / The situation
The product is far enough along that the next technical choice costs.
- The product or internal system is far enough along that stack, vendor, and AI choices now cost time and money.
- The founder can describe the business result and needs someone who can judge the technical path.
- A full-time CTO is the wrong hire at this stage.
03 / The sprint
A written pack. The product comes later, if you want it.
Working sessions produce a written pack. The product itself is built only if you choose a later engagement.
-
01
Decisions
What to build, what to buy, and what to stop, each with the reason.
-
02
Architecture
A target architecture for the next stage of the product or operation.
-
03
Sequence
A sequenced build plan, including who should do each part.
-
04
Next
A recommendation on what happens next: implement together, continue on a retainer, or take the plan and run it yourself.
04 / After the sprint
Three ways to continue.
- 01 Implement the plan with Rheeshaalaen.
- 02 Continue on a part-time retainer for the decisions that follow.
- 03 Take the plan and run it with your own people.
05 / Proof
Software and AI, shipped.
A payment flow he shipped
TrailBlazer Empire’s QR-only payment flow uses Maybank Biz QR. Orders are stored in D1. The Worker checks amount and quantity. Payment status can remain pending while the customer submits a bank transaction reference. The build took about 18 hours. It is a QR-only gateway.
AI in the workflow
He integrates LLM services into software and development workflows, including Claude Code and Langflow.
Boundaries
- The engagement is part-time technical direction, and later delivery, inside an agreed scope.
- The founder remains the executive.
- Team, budget, and board accountability sit outside this offer unless a later agreement includes them.
- The page is an offer of work. It is not a record of a past CTO appointment.
- Finance and capital advice are not this offer.
- Engineering employment history is on the Professional page.
06 / The conversation
Leave with the decisions, the architecture, and a build plan.
