A new SaaS product, built to last.
A new SaaS product, built to production standards from day one. Fixed scope, weekly demos, and I stay responsible for it.
I sign my name to a scope-of-work before a line of code is written.
Every Friday: live demo + Loom walkthrough. No silent sprints.
Code, repo, infra accounts, and docs. From day one.
Most new products do not fail on bad code. They fail on a scope that shifts every week until month four delivers a prototype instead of a product. This engagement is the opposite: a signed scope of work before any code exists, a phased plan with a concrete deliverable every Friday, and a production-grade stack from day one: real authentication, real billing, real observability. It is built the same way I built my own B2B SaaS, Carrier Intelligence: millions of records, sub-second search, and Stripe billing, solo from zero to production. Whether 6 to 8 weeks is realistic for your product is something I will tell you on the first call, not in week six.
You're the right fit if any of these land.
- →You have a validated idea with real users waiting, and you need someone to build it right.
- →You have been burned by a contractor or agency who took a deposit, delivered chaos, and disappeared.
- →Your investors, co-founder, or first customers are ready to see the product live and you need a date you can commit to.
- →You want production infrastructure from day one: Clerk/NextAuth, Stripe billing, Postgres, Sentry, CI/CD. Not duct tape.
- →You want weekly visibility into every decision, not a monthly status call that tells you nothing.
- →You want an honest answer on whether your timeline is realistic before you pay a dollar.
Six phases. One launch. No surprises.
Foundation
WEEK 1Monorepo, Postgres, authentication end-to-end (sign-up, session, RBAC), CI/CD pipeline, error tracking (Sentry), and a live staging URL. Zero day-one tech debt. You get a URL where auth works before week one ends.
Core Data & Billing
WEEK 2Data model, role-based access control, Stripe integration (products, subscriptions, checkout), and the design system wired in. The first end-to-end user journey is clickable.
Primary Feature Build
WEEK 3The feature your first customers will actually use every day. Not a placeholder or a mock, the real thing. Internal alpha ready for stakeholder review by Friday.
Expand & Integrate
WEEKS 4–5Secondary flows, edge cases, third-party integrations (Stripe webhooks, transactional email, analytics). Closed beta with 3–5 real users testing against their own data.
Harden & Optimise
WEEK 6Performance pass, security review (OWASP top 10), load test to your concurrency target, Core Web Vitals green. Every metric passes before we call it done.
Launch & Handover
WEEKS 7–8Production rollout, 30-day on-call support window, architectural decision record, runbook, and a local dev setup guide your next engineer can actually follow.
Not the right fit?
- ✗Idea-stage projects that have not been tested with a single potential paying user.
- ✗Founders who want to own architecture decisions and use me as an on-demand coding resource.
- ✗Projects that require more than one senior engineer working in parallel from week one.
