MVP speed. Production quality. One codebase.
Whether you're starting fresh or your AI-built MVP just hit its ceiling, I build your product on the foundation, so the version you launch is the version you scale.
Fit check
Who this sheet is drawn for.
Note — keep your frontend. If your AI-generated frontend is worth keeping, I build the production backend behind it. If it isn't, I'll say so before you spend money.
Fixed scope. Four steps. No retainer bleed.
A free call to understand what you're building and which gate fits: user or tenant.
Clear deliverables, honest timeline, one price. If scope changes, I re-quote and you decide.
Your features start where the plumbing ends. Weeks to MVP, not quarters.
Full source of your product, docs, and tests. The foundation stays licensed; see how it works.
You get the full source code of your product, including the foundation it runs on: build, host, and modify it freely for your business. The foundation IP stays with me, so you can't redistribute it or build new products on top of it.
Details on the pricing page→Already solved before I start
Auth, billing, tenancy, jobs, email, flags, caching — the plumbing your build starts on is already built and tested. The full specification of both foundations, and what each ships with, has its own page.
Read the foundation spec→Asked before. Answered straight.
For a demo, it isn't. AI tools win the first two weeks. But your MVP ships on a foundation that already carries 3,500+ tests if you're user-gated, or 6,500+ if you're tenant-gated, so you skip the rewrite that AI-built products need once they hit real users. One build instead of two is the faster path to scale.
Fair question, and the honest answer is that a solo engineer is a real risk you should price in. Here is what limits it: you get the full source, docs, and 3,500+ to 6,500+ tests at handover, so the product is never hostage to my availability. The stack is deliberately boring (.NET 10, PostgreSQL, Docker, clean architecture), so any competent .NET team can pick it up, and the test suite is the spec they read. And you can audit the code style before you hire me: Shopilent is public. What you lose if I disappear is my speed, not your product.
The full source of your product, including the foundation it runs on, with a perpetual license to run, host, and modify it for your business. The foundation IP stays with Ashersoft: you cannot redistribute it or use it to build new products on top.
Usually, yes. If your Lovable, Bolt, or v0 frontend is worth keeping, I build the production backend behind it and wire it up. If it isn't worth keeping, I'll tell you before you spend money.
I agree deliverables, timeline, and price with you before writing code. If you change the scope mid-build, I re-quote the change and you decide. You will never get a surprise invoice.
No. The fixed quote is split into milestones at the scope call, each with named deliverables you can run and review. A milestone is invoiced when its deliverables are in your hands, and you can stop at any milestone and keep the full source of everything you've paid for.
Ten-plus years of deep expertise, a mature ecosystem, and performance that holds on cheap hardware: Shopilent, my open-source .NET backend, sustained 458 req/s on a €4/month Hetzner CAX11 (2 vCPU ARM, 4 GB), with API, PostgreSQL, and Redis all on the same box. Boring, proven tech is a feature. Where Python is the right tool it gets used: the AI service is Python, with 400+ tests of its own.
Yes. Shopilent is an open-source .NET 10 e-commerce backend with 4,000+ tests across unit, integration, and architecture layers. It's public on GitHub, the clearest evidence of how the foundations are built.
Build it once.
