Selling complex technology
Pre-sales and solution design for vendors and integrators: positioning, the technical narrative, and a business case that survives the CFO's second question.
Independent technology consultant · Serbia & Spain
Most technology fails in the meeting, not in production.
Independent consulting on cloud, machine learning and applied AI. The solution gets designed, then explained to the people who have to sign for it — in plain language, with the economics worked out.
The work
Two languages, one decision
Engineering describes a system. The business decides on an outcome. Most projects stall in the gap between those two sentences — and that gap is where I work. Every proposal exists in both columns at once.
Managed Kubernetes, autoscaled across availability zones
A traffic spike stops costing you a night of downtime — and you stop paying for idle capacity the rest of the year
Speech-to-text and synthesis pipeline, tuned on your own domain vocabulary
Every customer call becomes searchable text, and your agents stop writing summaries by hand
Retrieval layer over your internal document base
New hires find the answer themselves instead of interrupting the one person who knows it
Phased migration from on-premise to hybrid, over two quarters
Capital expense becomes a monthly line you can forecast, defend, and cut
Services
Five things I get called for
Applied AI — and where it actually pays
Finding the places in your business where AI returns more than it costs, and saying so plainly when it doesn't. Pilots designed to answer a question, not to demo well. Agent factories included: how many agents, which systems they may touch, where a human signs off, and what one run costs.
Speech technology
Transcription and speech synthesis put to work: call analytics, voice interfaces, accessibility, media production. Model selection, tuning, and the pipeline around it.
Cloud, Kubernetes, Linux
Architecture and migration for infrastructure that simply has to keep running. An honest assessment of what you have, a plan for what you need, real numbers for both.
Development you can plan
Architecture, sizing and technical supervision for software other people build — mobile applications included. How hard the thing really is, what it will cost, which parts are risky, and whether the plan survives contact with a team. I don't take the keyboard.
The arithmetic
Run your own numbers
Idle capacity is the cheapest money on the table and the least often counted. Put in what you actually run — this is your arithmetic, not my estimate, and it stays in your browser.
Paid for nothing, per year
per month
The number is only the ceiling — some of that capacity is headroom you chose on purpose. Telling the difference is most of the work.
Stack
What the advice is built on
Seventeen years inside global technology companies — enterprise infrastructure, cloud platforms and machine learning, on the side that has to deliver what was sold. Long enough to know which promises hold after the contract is signed.
Infrastructure
- Public cloud platforms
- Kubernetes & containers

How it is built
What to keep, what to rent
The same stack, split by one question asked layer by layer: does owning this buy you anything? Hardware and the workloads on top usually stay. The middle usually does not.
On-premise
Cloud
-
kept Workloads the only layer your customer sees
-
rented Autoscaling capacity that answers to demand
-
rented Kubernetes control plane, then the nodes
-
rented Storage and its backups, which are not the same thing
-
kept Network routing, peering, firewalls
-
kept Linux the boring, load-bearing part
-
kept Bare metal racks, power, hands
Four layers kept because they have to be yours, three rented because owning them buys nothing.
About
Who you would be working with
Anton Gostev
Consultant, entrepreneur, engineer
My name is Anton Gostev, and I spent seventeen years inside large technology vendors: eleven at Microsoft, three at Yandex International, two at IBM and one at Dassault Systèmes.
The work always had the same shape — standing between an engineering team and a customer who has to sign, and making sure both were describing the same thing.
Today I do it on my own, through two registered practices: one in Serbia, one in Spain. You talk to the person who does the work, because there is no one else to hand it to.
Where those years went
- Microsoft — 11 years
- Yandex International — 3 years
- IBM — 2 years
- Dassault Systèmes — 1 year
How an engagement runs
Three steps, in this order
Step 01 — Assess
Find out what is really there
A week or two: what you run, what it costs, where it hurts, and what the team already knows but hasn't been asked.
Step 02 — Plan
Decide what is worth doing
Architecture and a costed roadmap that separates what to do now, what to defer, and what to drop entirely.
Step 03 — Execute
Stay until it works
Hands-on, alongside your team, or reviewing a vendor's work from your side of the table. Whichever the situation calls for.

Tell me what's not working
A first conversation costs nothing and usually takes half an hour. If I'm not the right person for it, I will say so and point you at someone who is.
What the first call looks like
- I don't sell anything on it — not on the first call, and not on any later one. I listen, and I ask questions.
- What I'm after is not only the problem, but where it came from: what caused it, or what it is a consequence of.
- And what you have already tried. The experience a team picks up while failing to fix something usually decides what will actually work.
