Hands-On CTO & AI Leader
I lead technology and AI for startups and scale-ups: strategy, architecture, team, and the decisions that are expensive to get wrong. And I still write the critical code myself. Available as fractional CTO, technical advisor, or AI lead.

Track record
Engineering leadership
Engineering Manager at Job&Talent. Before that, Head of Frontend and Tech Lead of the Platform team at Doxy.me, a telehealth platform.
Founder, CEO & CTO
Founded Clariox, an AI speech-coaching product, and took it from idea to production.
Fractional CTO
CTO-level ownership for founders in fintech (BankSmyth) and SaaS (Monthlee): strategy, architecture, and launch.
AI in production
Led AI products from PoC to release: real-time LLM pipelines, RAG, and multi-provider speech AI (Echios, Clariox).
Bring me in when…
- You are a founder without a technical co-founder and need someone to own technology at CTO level, without a full-time executive hire yet.
- You are betting on AI and need someone to set the strategy, choose the stack, and get it to production reliably and at a sane cost.
- You are raising, acquiring, or investing and need technical due diligence from someone who has built and run the kind of systems being evaluated.
- Your team is shipping, but nobody senior owns the architecture, and you cannot tell whether the decisions being made are right.
- Your platform has outgrown its first architecture and you are facing a rewrite, migration, or scaling decision you cannot afford to get wrong.
- Your technical lead left, or an agency or AI tool built the product, and you need someone to take ownership now.
Who I work with
Founders & CEOs
“I need a technical partner at co-founder level, not another contractor.”
I own the technology function with you: roadmap, architecture, hiring, vendors, and the decisions that are expensive to get wrong. Reported in business terms, and built hands-on where it matters.
Investors & Boards
“Is this company’s technology an asset or a liability?”
Independent technical due diligence and post-investment oversight, written for people making capital decisions: what is sound, what is risky, and what it will cost to fix.
How I Can Help
Start where the risk is highest. Most engagements begin with a review or a strategy call and grow into an ongoing leadership role.
Fractional CTO
Technology leadership for founders who need someone to own the whole function, and still be able to open the codebase.
Includes:
- Technology strategy, roadmap, and architecture decisions
- Hands-on ownership of critical systems, migrations, and modernization
- Hiring, team structure, vendors, and delivery oversight
- Fundraising diligence, board reporting, and risk management
Best for: Founders and CEOs who need ongoing CTO-level ownership without a full-time executive hire.
Technical Advisor
A senior, independent voice for founders and boards who do not need a CTO every week, but need one for the decisions that matter.
Includes:
- Regular strategy sessions, and on call for the big decisions
- Review of architecture, roadmap, hiring plans, and vendor choices
- Independent read on your team and your technical leads
- Preparing the technology story for investors and the board
Best for: Founders with a capable team who want a trusted senior sounding board, and boards that want independent technical oversight.
AI Strategy & Architecture
From AI strategy to systems that work in production: reliably, measurably, and at a cost that makes sense.
Includes:
- AI strategy, build-vs-buy, and model and provider selection
- LLM, RAG, and agent architecture with evaluation and cost governance
- Leading delivery from PoC to production and upskilling your team
Best for: Companies making a real bet on AI that need senior ownership beyond the demo.
Technical Due Diligence & Architecture Review
An independent, senior read of the product, architecture, infrastructure, team, and delivery before the money is committed.
Deliverables:
- Written report with a prioritized risk map
- Architecture, scaling, security, and cost findings
- 30/60/90-day technical action plan
Best for: Fundraising, acquisitions, investment decisions, launches, and rewrite-or-not calls.
Engagement models
You are not buying hours. You are buying ownership of the decisions that are expensive to get wrong.
Fractional CTO
Monthly retainer, 1-2 days/week. Own the technology function: strategy, architecture, team, vendors, and board reporting.
Technical Advisor
Monthly retainer, a few hours per week. Strategy sessions, decision reviews, and on call for the moments that matter.
AI Strategy & Architecture
Monthly retainer, 1-2 days/week. AI strategy, architecture, and delivery to production.
Technical Due Diligence & Architecture Review
Fixed scope, 1-2 weeks. The easiest way to start: an independent picture of what is sound, what is risky, and what to do next.
Due diligence and reviews are priced as fixed-scope projects, agreed up front with no open-ended hourly billing. Fractional and advisory engagements run as simple monthly retainers, a fraction of the $250,000-$350,000/year cost of a full-time CTO.
How it works
Strategy Call
We talk through your product, team, and goals. No pitch, just a clear read on where you stand.
Assessment
I review your technology, architecture, team, and delivery, and identify the risks and opportunities that matter.
Roadmap & Decisions
You get a clear plan: what to build, what to fix, what to skip, and the decisions I recommend and why.
Ownership & Execution
I take ownership as fractional CTO or AI lead, or stay close as technical advisor, and implement the critical parts myself where it matters.
What clients say
Real messages from people I've worked with.
Currently accepting 2-3 new engagements this quarter.

Why Early-Stage Startups Need a Hands-On CTO, Not Only a Strategy Leader
Early startups need hands-on CTO leadership to make architecture, product, and engineering decisions before technical mistakes become expensive.
