Four ways
to work together
SaaS MVP Build
A full-stack MVP built to show investors or onboard real users — not a prototype. Auth, database, AI features, billing, and deployment. Done in 4–8 weeks.
Start your MVP- →Product scoping and technical planning
- →Next.js frontend + Node.js backend
- →Authentication and core user workflows
- →Database setup (Supabase / Postgres)
- →Stripe billing + admin dashboard
- →AI features (RAG, agents, integrations)
- →Weekly demos throughout the build
- →Deployment-ready + 2 weeks post-launch support
AI SaaS Retainer
An embedded senior AI engineer who knows your codebase and roadmap. Steady output every month without a full-time hire.
- →40 hrs/mo, outcomes-focused delivery
- →RAG, agents, voice AI, embeddings
- →Backend, API, Supabase/Postgres work
- →Architecture decisions and code review
- →Weekly sync + async Loom updates
AI Architecture Audit
A clear, honest read on where AI fits in your product — before you spend months building the wrong thing. Includes a prioritised 90-day roadmap.
- →AI feature opportunity analysis
- →Recommended stack + risks + costs
- →Written findings doc you can share
- →Cost credited toward a retainer or project
AI Feature Integration
Production-grade AI added to your existing SaaS. Clean integration into your repo, properly architected, documented and tested.
- →RAG pipeline (pgvector, LangChain, embeddings)
- →OpenAI agents and tool use
- →Voice AI (ElevenLabs, LiveKit, Tavus)
- →Multi-tenant document ingestion
- →White-label / agency subcontracting OK
How engagements
typically start
Send a few sentences on your product and the AI problem you're trying to solve. No deck required.
30-minute call to align on goals, stack, and whether this is the right fit — for both sides.
A clear proposal: fixed price or retainer, deliverables, timeline. No surprises later.
If it's a fit, first work starts within days. NDAs and contractor agreements are standard.
Why AI engineers
usually disappoint
Most founders waste the first three months building the wrong version of their product. They over-engineer features users don't need yet, or under-build the things that actually matter for a first demo — and end up with something that's neither shippable nor fundable.
I've spent 15+ years shipping full-stack products across SaaS, fintech, and enterprise. My focus is the fastest path to a usable, production-ready v1: define the leanest scope, build the core flows properly, and deliver something you can put in front of real users.
That means auth that works, a database schema that won't need a full rewrite, billing you can actually charge through, and AI features that aren't just a wrapper around an OpenAI call. Every project includes weekly demos so there are no surprises at the end.
I work with non-technical founders, early-stage startups, and teams that need a senior builder who can also shape product decisions — not just execute a spec.
Core stack
What clients say
“Alex is the consummate professional, and he is highly skilled. I trust him with our projects. When Alex is on a project, we know it will be done correctly and on time.”
“Alex is a world-class developer who is head and shoulders above what is considered standard. All work was completed way ahead of time — we had a hard time keeping up to give him new tasks.”
“Excellent understanding of tasks. Great communication and very efficient. Alex has been a pleasure to deal with among a sea of complicated and frustrating freelancers. A breath of fresh air.”

Not sure what
to build first?
A 30-minute strategy call is enough to map the right scope, timeline, and budget for your MVP. No deck required — just a description of what you're trying to build.
