I'm Igal Malisov.
I build the hard parts
of AI products.

20+ years building data-intensive, high-performance systems. I partner with early-stage B2B SaaS founders who need a senior technical mind — someone who owns the decisions, not just executes them.

Most AI products are built wrong.
You only find out in production.

By then you're six months in, rewriting everything. I've seen this exact pattern too many times.

Hardcoded prompts, no versioning

Every change is a risk. Nobody knows what's live and what was tested. Debugging becomes archaeology.

No cost controls or observability

Your AI bill triples overnight and you have no idea why. No dashboards, no alerts, no cost ceiling.

Missing retry logic and fallbacks

One failed API call takes down your entire pipeline. Users see errors. Trust is hard to rebuild.

Architecture that can't scale

What worked at 10 users breaks at 1,000. Rebuilding always costs more than getting it right the first time.

For founders who can't afford
to rebuild in six months.

I work with a small number of clients at a time. I'm selective because the work demands real depth.

01

No technical co-founder

You need a senior technical partner who owns architecture decisions and holds the team accountable — not someone who just takes tickets.

02

Early-stage with funding or paying clients

You have something real to build. The problem is getting it built correctly at a pace that matches your growth.

03

Building with AI and hitting walls

Your product uses LLMs, agents, or data pipelines — and getting them production-ready is turning out to be harder than the demo suggested.

04

Need to move fast without accumulating debt

You can't wait six months to hire a CTO. But you also can't afford to move fast and break the foundation you're building on.

Senior execution,
not consulting decks.

Architecture decisions, code, systems — things that ship and hold up under pressure.

01 —

AI Product Architecture

Design and build LLM-powered products that work in production. Prompt versioning, agent orchestration, cost controls, observability, and reliability — from day one, not bolted on later.

02 —

Backend & Distributed Systems

High-performance APIs, data pipelines, and distributed architectures built to handle real load. Not demo traffic — production traffic with real users and real consequences.

03 —

0→1 Product Development

From whiteboard to working product. Full technical ownership: architecture, stack decisions, implementation, deployment. I've done this multiple times — the speed comes from not making the same mistakes twice.

04 —

Fractional CTO

Ongoing strategic technical leadership — hiring decisions, vendor evaluation, architecture reviews, roadmap sanity-checks, and keeping your team moving in the right direction without burning out.
