For funded AI SaaS startups
Senior AI SaaS engineering, before you're ready for a full-time CTO.
I'm co-founder & CTO of BFEAI, a 7-app AI SaaS platform shipping in production today. I take a small number of contract engagements alongside that role.

What's running in production:
- Cross-app SSO via custom JWT across 7 Next.js / TypeScript apps with refresh-token rotation
- Stripe subscription + dual-pool credit billing with webhook reconciliation as a first-class concern
- Multi-tenant Supabase with row-level security spanning all apps and tenants
- 6-engine LLM orchestration layer (ChatGPT, Gemini, Perplexity, Claude, Google AI Overview, AI Mode) with prompt-drift handling and cost tracking
- Python automation services (FastAPI + Celery) orchestrating headless browser fleets at scale
- DataForSEO-driven keyword research pipeline with budget tracking and CTR-based traffic estimation
Who you're hiring
Bill Fackelman
Co-founder & CTO, BFEAI
I've spent the last 5 months shipping 7 production AI SaaS apps as co-founder and CTO of BFEAI. I take on a small number of contract engagements alongside that role, working with funded founders past MVP who need senior engineering before they're ready to commit to a full-time hire.
From the team I ship with
What it's like to work with me.
“Bill shipped our Stripe billing redesign (credit ledger, dual-pool drain semantics, idempotent webhooks) in two weeks. The kind of work most teams scope for six. It's been running in production without a single revenue-leak bug.”
Josh B.
Co-founder, BFEAI
“We were about to spin up a separate Supabase project for each app. Bill pushed back, designed the multi-tenant RLS approach across all seven apps, and the entire platform is one cohesive system because of that call. That's the difference between a senior engineer and a fractional CTO.”
Ryan M.
Co-founder, BFEAI
“Bill built cost-tracking, error-tracking, and observability into the LLM orchestration layer before any of it was urgent. When usage grew, we didn't have to rebuild a thing. Most engineers ship the demo. Bill ships the operations.”
George J.
Co-founder, BFEAI
“Shipping seven multi-tenant apps in five months means making the right tradeoff a hundred times a week. Bill is the partner I make those calls with. He pushes back when I'm about to ship something that won't hold up, and he builds the thing the right way once we've agreed on the call.”
Kyle S.
Co-founder, BFEAI
Four ways to engage
You don't need a full-time hire to ship the next 6 weeks.
Availability
BFEAI runs on an async-first ops cadence, which frees 10–15 hours a week for outside engagements. I take on one or two clients at a time so each gets real focus. Currently accepting 2 new clients.
Ship the next phase
Most common$100–150/hr • 6–8 weeks
Scoped build on your stack: Stripe billing redesign, RAG pipeline, multi-tenant migration, auth hardening. Hourly with a hard cap per phase so you always know the ceiling.
Migrate off your no-code stack
Scoped fixed • typically 4–6 weeks
Most no-code migrations underestimate the state machine the platform was hiding. I plan for that explicitly. Output: maintainable TypeScript that survives load and the next API change.
Fractional CTO
$8–15K/mo • 10–15 hrs/week
Architecture decisions, hiring help, code review, founder sounding-board. Quarterly review of the engagement shape. For founders who want senior depth on the bench without a full-time CTO comp package.
How I build
Boring tech, picked on purpose.
Founders hire senior contractors hoping for senior judgment. What they actually need: someone who resists the tooling-of-the-month and ships the smallest thing that holds up under load.
What I default to
- TypeScript everywhere. Postgres for anything that touches data.
- RLS for tenancy. Stripe for anything billable.
- Python only where it's the right tool: browser fleets, data pipelines, ML serving.
- Whatever LLM API the use case actually needs.
- The smallest version that holds up under load.
What I push back on
- Microservices before you need them.
- Exotic ORMs and "innovative" data stores.
- Premature observability platforms.
- Anything you have to operate that isn't your product.
- Rewrites when refactors would do.
Who I'm a fit for.
Good fit
- YC / seed / Series A AI SaaS with a live product and paying customers
- Technical founder past MVP, feeling the engineering ceiling approach
- Pre-full-time-hire: runway or PMF uncertainty makes a $250K hire feel premature
- Teams hitting the Make / Zapier / Airtable ceiling and ready for maintainable code underneath
- Stripe billing edge cases, multi-tenant RLS surprises, RAG that needs to actually answer questions
Not a fit
- Pre-funding / pre-product (rate doesn't work)
- Looking for a junior or mid-level developer
- Need a CTO who'll go full-time (I have a CTO role already)
- Consumer hardware, biotech wet-lab, defense, crypto / NFT / Web3 tokens
- Need SOC 2 / HIPAA compliance ownership on the contractor
