[PRODUCT ENGINEERING MANIFESTO]
Senior engineering without the agency layers.
The person on your scoping call is the person making the architecture decisions and building the product.
PILLAR 01 // OWNERSHIP
Single Point of Ownership
Figma to Postgres without translation loss.
Interface design, component architecture, state management, APIs, database schemas, and deployment stay with one senior engineer. Product context stays connected from the first decision to the live release.
PILLAR 02 // AI INFRASTRUCTURE
Production-First AI
Sub-50ms edge inference, vector pipelines, deterministic fallbacks.
AI features are never treated as superficial wrapper novelties. Systems are engineered with strict latency budgets, token optimization, visual fallback heuristics (such as computer vision with barcode UPC fallbacks), streaming response pipelines, and hardened Zod contract validation.
PILLAR 03 // DESIGN SYSTEMS
Design-System Rigor
60fps gesture-driven interfaces, custom micro-interactions.
Native fluid motion, mathematical typographic scales, and responsive tokens scaling from 375px mobile to 4K ultra-wide workstations. Interfaces are built to WCAG AA accessibility standards with tactile micro-interactions that make complex systems feel effortless.
A 15-person agency roster—or one accountable senior engineer?
Multi-Layer Agency Model
- Communication routed through account managers
- Design and engineering split across handoffs
- Your fee covers coordination as well as production work
- More people involved in every product decision
KD Studios Single-Point Ownership
- Direct access to the senior engineer doing the work
- Product, design, and engineering under one owner
- No account-manager layer added to your engagement
- Short feedback loops tied to visible milestones

[FOUNDER SPRINTS // TWO WAYS TO BUILD]
Ship the first version founders can use—in 2–3 weeks.
Choose a fixed launch sprint or reserve ongoing senior product leadership. Either way, you work directly with the engineer designing, building, and shipping the product.
Strictly limited to 2 active builds per month
Best for a first launch
Fixed-scope launch sprint
Rapid MVP Sprint
One valuable core flow, designed, built, and ready for real customer feedback.
From $4,500
- 90-minute kickoff, scope lock, and technical roadmap
- UX and interface design for the critical product flow
- Full-stack web, mobile, or AI implementation
- Production deployment, handover, and launch checklist
14–21 day delivery commitmentThe agreed sprint scope ships on time—or I keep working at no extra fee until it does.
Start with a free technical teardown
15 minutes. No sales rep. No sales pressure.
Best for ongoing velocity
Ongoing senior product partner
Dedicated Product Retainer
Senior product engineering embedded in your business—without the delay or overhead of a full-time hire.
Monthly engagement
- Direct Slack access to Kiavash—no account-manager layer
- Weekly priorities and visible delivery decisions
- Design, full-stack engineering, and continuous releases
- Fractional CTO and lead-developer guidance
You speak directly with the engineer doing the work.

The cost of waiting
Every week in planning is another week without user feedback.
You do not need a bigger roadmap. You need the smallest valuable version in real users’ hands—so the next decision comes from evidence, not another planning meeting.
[60-SECOND PROJECT BRIEF]
Get an initial roadmap and fixed-scope quote.
Three quick choices. I’ll review the brief myself—no account managers or sales handoffs.
Free 15-minute technical teardown includedBring the idea or current stack. Leave with the biggest technical risk and the clearest next step.
[ANSWERS BEFORE THE FIRST CALL]
Questions founders usually ask.
A practical starting point for deciding whether a senior, single-owner engagement fits your product.
What does KD Studios build?
KD Studios builds AI-enabled products, full-stack web applications, and React Native mobile apps. The work spans product definition, interface systems, APIs, data models, deployment, and the production feedback loop.
Can an MVP really ship in 2–3 weeks?
Yes—when the sprint is limited to one clearly defined core flow and required accounts, content, and feedback arrive on schedule. Larger scopes are split into visible milestones before kickoff.
What does the $4,500 starting price include?
It covers a tightly scoped MVP sprint. After the scoping call, you receive a written scope, timeline, acceptance criteria, and fixed price before work begins.
What if Milestone 1 misses the agreed standard?
I correct it within the agreed review window. If it still misses the written acceptance criteria, we stop and you owe $0 for that milestone.
[DIRECT CONTACT]
Turn the idea into something users can react to.
Request 15 minutes directly with me. We’ll identify the smallest credible launch, the main technical risk, and whether a sprint is the right fit.
No sales reps. No pressure. Just a technical conversation with the engineer who would do the work.
