What We Deliver

Four outcome-priced offerings. Pick the one that maps to the gap in your business. Every engagement is fixed-price and milestone-based. No hourly billing. No timesheets. No scope creep.

🚀

Zero-to-Production SaaS MVP

From idea to live deployment in 21 days. Auth, payments, REST API, admin panel, and production deployment on your infrastructure. You own 100% of the IP, source, and root keys from Day One — no vendor lock-in.

From $15,000

🤖

Deterministic AI & LLM Pipelines

Production-grade LLM integrations, RAG systems, autonomous subagents. Built to eliminate hallucination risk and integrate cleanly with your existing backend. Includes monitoring, caching, and rate limiting as standard.

From $8,000

🛡️

Bulletproof Backend API & Infrastructure

REST or GraphQL API engineered to scale to 10K+ users from Day One. Self-hosted or cloud, with CI/CD, automated backups, monitoring, and a 30-day code warranty. We hand off the keys — you own the infrastructure.

From $6,000

🔍

Surgical Codebase Health Audit

48-hour deep audit of your existing codebase. You get a prioritized refactoring roadmap, security gaps, performance bottlenecks, and architectural recommendations. Pre-acquisition due diligence or pre-scale code review.

From $3,000

How We Engage

Every engagement runs on the same five policies. They are not negotiable. They exist so the work ships on time, the budget holds, and the IP is yours from Day One.

🛡️

14-Day Mutual Alignment Guarantee

If within 14 days the engagement is not the right fit — communication style, technical direction, or pace — you get 100% back, no questions asked. We absorb the onboarding cost. The first two weeks are paid only if both sides commit to the full project.

⏱️

Async-First Execution

Maximum one weekly sync call. Everything else happens via text, recorded Loom videos, and pull requests. You do not need to clear your calendar. You do not need to attend standups. Decisions are documented, not lost in meetings.

🔑

Clean Handoff & Full IP Ownership

From Day One you own 100% of the source code, infrastructure keys, and documentation. No vendor lock-in. No proprietary frameworks. No hostage situations. If we disappear tomorrow, you keep everything and run it yourself.

🎯

Fixed-Price Milestone-Based Billing

The total project price is set on Day One. Payment is tied to milestone delivery, not hours logged. We absorb scope creep. We refund milestones that miss. The budget you approved is the budget you spend.

🔧

30-Day Code Warranty

After deployment, any bug traced to our code is fixed free of charge for 30 days. The warranty is explicit, written into the contract, and honoured without invoicing theatre. Past that, we offer monthly support retainers from $400.

Who We Work With

Non-technical founders and C-suite executives who have already validated the business and need a senior technical partner to take an idea, a codebase, or an infrastructure from where it is to where it needs to be. We are not a fit for hourly staff augmentation, code-monkey work, or micromanaged engagements. We are a fit when you want a CTO-grade decision-maker in the room, on a fixed budget, on a fixed timeline.

Ready for a CTO-Grade Technical Partner?

Send us your stack, your idea, or your codebase. We will send back 3 concrete architectural improvements within 48 hours — free, no commitment.
