You will get a 1-hour CTO consultation: architecture, hiring, or DD prep
Project details
For founders, CTOs, and senior engineers with one specific technical question they want a 20-year operator to weigh in on. Investor diligence prep, build-vs-buy, an architecture sanity-check, a hiring plan, or "do we actually need a fractional CTO right now?" — bring the question, I'll bring two decades of context.
WHAT YOU GET
• 60-min video call (within 5 working days)
• 1-page written memo within 48h after — recommendation, two or three alternatives I considered, and specific next steps with owners
• Mutual NDA signed on request before the call
RECEIPTS
Currently Technology Director at Playkot. Designed a 1.5 PB self-hosted ClickHouse platform delivering a Snowflake-equivalent stack at ~50% TCO. Hired 70+ engineers across 10 countries. Presented architecture during a $3M Series A close. Shipped six mobile titles to 50M+ MAU combined. Multi-vertical on purpose — SaaS / Big Data, games, AI-assisted engineering.
NOT A FIT IF you want a decision rubber-stamped, hands-on code on the call, or your domain is crypto / NFT / gambling / dating.
Introductory rate while building Upwork track record — will return to standard rate after 3–5 reviews.

About Viktor
Fractional CTO | SaaS, Data Platforms, AI Engineering and GameDev
Mesa Geitonia, Cyprus - 4:16 pm local time
I designed and operated a self-hosted ClickHouse + Ceph platform at 1.5 PB / 2 TB-per-day with a 99.99% SLA — roughly 50% the TCO of a managed AWS-equivalent stack (~$170K/year saved). The client was a VC-backed mobile market intelligence platform (name available under NDA), now #2 in its category. That's the experience I bring to teams deciding between Snowflake, BigQuery, ClickHouse, or self-hosted — the right answer is rarely the vendor's preferred answer.
Other ground I cover: 6 shipped game titles at 50M+ MAU (incl. World Poker Club, 10M+ downloads), a custom Go + Vulkan engine, and a 500K-LOC ActionScript → TypeScript migration. Most recently at Playkot, AI-assisted dev workflows have cut iteration cycles 5x, and I shipped an AI-creatives B2B MVP in 3 weeks.
Strongest at: pre-Series A architecture, technical due diligence, hiring at scale (the #1 reason early-stage teams stall), big-data cost optimization, and AI-enabled product / dev workflows.
What I'm looking for: 2–3 long-running fractional engagements (15–20 hrs/week each), not transactional gigs.
Currently offering an introductory rate while building my UpWork track record — happy to start with a fixed-scope engagement (architecture review, 1-day technical assessment, or trial fractional week) so we can both see fit before committing.
