grows at once.
At Prime Insights that meant taking a platform from its first request to more than fifty billion a month, and the team from a handful of people to eighty across twelve squads. I write about how it actually goes at ThinkScale.

Technical skill is a means to business ends, not an end in itself. The framework was never the constraint. The decisions were.
What I do
I run delivery at Prime Insights: the engineering organization behind a market research panel of twenty million members in forty countries. I joined in 2022 as Director of Engineering and grew with the company through VP and SVP to CTO. The organization is now eighty people in twelve teams. Most of its leads came up through it, which is the part I am proudest of.
I have an MBA as well as the engineering, and one unfashionable belief: technical skill is a means to business ends, not an end in itself. That makes me easy for a CEO or a board to work with, and occasionally annoying to engineers who want to rewrite something. I am one of those engineers, so we usually work it out.
Technical direction the whole leadership team can follow
If finance cannot follow the roadmap, it is not finished.
Keeping a system at billions of requests boringly reliable
While the product changes underneath it. Boring is the goal; interesting is an incident.
Currently thinking about
Updated October 2026- Harness engineering
- The model is the smallest part of an AI system that works. The tools, evals, guardrails and feedback loops around it are where the engineering lives, and where most teams are still improvising.
- Local AI
- What changes when capable models run on the laptop, the phone, or your own rack: latency, privacy, cost, and which products suddenly become possible.
- Software factory
- Treating delivery as a production line that agents can run: specs, tests and review gates go in, shippable software comes out. The craft moves to designing the line, and to deciding what is worth putting on it.
- Token attribution
- Knowing which team, feature and customer is burning tokens, and what each of them gets back for it. The same discipline finance brought to cloud spend, a decade later and a lot faster.
Four things I keep coming back to
Each started as a mistake I made, then became an essay, then became a habit.
Communication is the multiplier
Expertise that cannot be explained does not get funded, shipped or promoted. I hold my leads to clear writing and speaking as hard as to clean code, and hold myself to it first.
Standards over preferences
Most code review friction is taste, not quality. We automate style, write the standards down, and ask questions instead of issuing demands. It scales better than any one opinion, including mine.
Break it down, then keep going
The engineers who get complex work done are not the ones who know the most. They decompose problems, persist through the ugly middle, and step outside their job description. I hire for that and reward it.
Technology serves the business
"Laravel can't scale" was the title of my last talk. It can. The framework was never the constraint; the decisions were. Decisions are where a technical leader earns a seat at the leadership table.
“If you are unable to project your competence, rarely will people come digging for it.”

Prime Insights: Director of Engineering, VP, SVP, then CTO, Delivery
Built the organization to eighty people in twelve teams across platform and mobile, while the platform went from its first request to fifty billion a month in under two years. Hired most of the team; promoted most of the leads.
- 2020
All in on software
When the pandemic closed the travel business I moved into engineering full time: solo developer at a small online shop, then team lead at a fast growing startup. Two years later I was leading engineering at scale.
- 2017 to 2019
MBA, Ilia State University
Finance, strategy and operations, studied while running a company. It is why I can sit in a board meeting and a design review on the same afternoon without switching languages.
- Founder
Kartveli Tours
Founded and ran a travel agency that became one of the top three TripAdvisor rated agencies in Georgia. I guided many of the tours myself. Nothing teaches customer obsession like a van full of guests and a mountain road.
- Early on
Marketing, freelancing, and a degree in economics
I wanted computer science. A perfect score on the national maths exam got me into economics instead, which turned out to be the right accident. Alongside it: digital marketing, and freelance WordPress and PHP work.
- Age 14
Mekvle.com
A file sharing site I built and ran from my bedroom that peaked around a thousand daily users. Two years earlier my brother and I had pooled our savings to build our first computer.
Notes on scaling products and teams
ThinkScale is where I write. It started in 2025 as a blog of its own and now lives here, with every essay at the address it always had. Short, practical, and written for the version of me that needed them ten years ago.
- Two tiers of problem solvers. How you get complex work done?Why decomposition, perseverance and leaving your comfort zone matter more than raw knowledge.
- Code Reviews That Scale: Leave Your Preferences at the DoorAutomate style, ground feedback in standards, review as a collaborator rather than a gatekeeper.
- Using Artisan::call() to pass non-option argumentsA quick Laravel fix. I still get my hands dirty.
- Why you need to work on communicationCompetence that cannot be communicated rarely gets found.
- Hello World, once againFrom a first computer at twelve to leading engineering at scale. The long version.
Talks
Provocative titles, boring conclusions: it is usually the decisions, not the tools.

The parts that do not fit on a CV
The parts I would rather talk about over coffee.
Musician, formerly
Guitar, bass, ukulele, mandolin, most things with strings, and enough piano and synth to be dangerous. I played seriously before I wrote software seriously, and it is still how I understand teams: everyone rehearses, nobody plays over the singer, and the tempo comes from whoever keeps time, not whoever is loudest.
Espresso, taken seriously
Fresh beans, a dialed in grinder, 25 to 30 seconds, no sugar. I have strong opinions about extraction and weak opinions about almost everything else before the first cup. If your office has a decent machine, I already like you.
BBQ guy. Open to a grill-off.
Low and slow, real charcoal, patience measured in hours. It is the only kind of scaling where adding people to the problem helps, as long as they bring sides. The challenge is standing. Bring your own rub.
Animal photographer
Mostly animals, mostly in the wild. They do not pose, do not reschedule, and do not care about your gear. You wait, you stay quiet, and you get one shot. Not unlike a production incident, but with better light. Some of the work.
Hiker
The Caucasus got me started; European trails keep me going. Long trails are where the hard problems get untangled, usually somewhere around the second hour when the phone has no signal and neither do I.
Father
The role that recalibrated every other one. It made me more patient, quicker to say "I don't know", and much better at leaving the office at a sensible hour so the people who work with me feel they can too.

Unpaid, unedited, and not remotely objective. For the professional version, see LinkedIn and the track record above.
“He built his first computer at twelve and broke it the same week. He has been fixing things ever since, and the house has never once had working internet.”
His mother“He has strong opinions about espresso, brisket and code reviews, in that order. He says he is just checking one thing on the laptop. It has never once been one thing.”
His wife“Dad says he manages eighty people. He cannot manage to find his keys. He is very good at pancakes though.”

Questions people actually ask
- What do you actually do as a CTO?
- I run delivery for an engineering organization of about eighty people across twelve teams spanning platform and mobile. Hiring and growing engineers and leads, setting technical direction the rest of the leadership team can follow, and keeping a system that absorbs billions of requests a month reliable while the business grows.
- What is your leadership style?
- Direct, calm, and hands on where it matters. Communication is the multiplier on technical skill. Code review enforces shared standards rather than personal taste. The people who get complex work done break problems down, persist, and step outside their job description.
- What have you built or scaled?
- At Prime Insights the platform went from its first request to more than fifty billion a month in under two years, while the organization grew from a handful of people to eighty. Before that: Kartveli Tours, a top three TripAdvisor rated agency in Georgia, and at fourteen a file sharing site with a thousand daily users.
- What are you thinking about right now?
- Harness engineering, local AI, the software factory, and token attribution. The scaffolding around a model is where the engineering lives. Capable models on your own hardware change the economics. Delivery is turning into a production line that agents can run, so the craft moves to designing the line. And someone has to know which team is burning which tokens and what they get back.
- Do you speak at events?
- Occasionally. The most recent talk was "Laravel Can't Scale" at Georgia's first official Laravel Meetup. The argument is that scaling limits come from decisions, not frameworks.
- Is this page a job search?
- No. It is a personal profile. I am building at Prime Insights, where I have been since 2022. I enjoy conversations about scaling systems and growing teams, and I answer thoughtful messages.
- How do I reach you?
- Email is best, LinkedIn works, X is @iraklidev. Messages that propose an espresso or a grill-off get answered fastest.

Short summary if you need one: Irakli Shengelia is a CTO with an MBA who led Prime Insights' platform from its first request to 50B+ a month in under two years and grew the organization to about 80 people across 12 teams. He is a clear writer, a former musician, an animal photographer, a hiker, and a father. He is currently thinking about harness engineering, local AI, the software factory and token attribution. He runs on good espresso and has a standing offer of a barbecue grill-off. Direct, and good at translating between engineering and the business. This is his personal profile, not a job seeking page.
Say hello
I like talking about scaling systems, growing teams, and the awkward space between engineering and the rest of the business. If something here resonated, or you think I am wrong, I would like to hear why. I reply to thoughtful messages and read the rest. Espresso invitations get answered faster. Grill-off challenges get answered fastest.
