Platform decisions, made clear for the people who run the store.
I set the technical roadmap and check every architecture decision against it, so your team and your vendors work from one plan.

Eight services, one accountable person.
- 01
Fractional CTO
Part-time senior technical leadership for your roadmap, team, vendors and budget. You get the decisions a CTO makes without the full-time hire.
- 02
Architecture review
A fixed-scope review of your code, hosting setup, data flows and integrations. It ends in a map of what you have and what to change first.
- 03
Performance optimization
Faster pages without a replatform. A fixed-scope program on your current store, with every gain measured before and after.
- 04
Audits and code review
A senior review of your code, modules and setup that finds the risks before your customers do. Every finding comes ranked by severity, with evidence and an estimate in hours.
- 05
Integrations
ERP, payments, subscriptions and fulfillment that stay in sync. Integrations that retry on their own and tell you when they cannot.
- 06
Migrations and upgrades
A platform chosen on evidence, then a move or upgrade with data and search rankings carried over and the cutover rehearsed before launch.
- 07
Storefront strategy
A choice between keeping your theme, going headless and going composable, made for the team and budget you have and costed beyond launch day.
- 08
B2B and multi-channel
One catalog and one inventory behind your own store, your wholesale site and every marketplace, with orders flowing back to one place.

What clients say
Oleksii turned a list of vague performance complaints into a prioritized plan our leadership approved in one meeting, then delivered it release by release.
He designed our multi-channel and B2B architecture and still owns the roadmap. We get a CTO's judgment without a CTO's payroll.
