CTO | Designing and optimizing digital systems for business scaling.

Fractional CTO | Lead PM | Business Systems & IT Infrastructure Architect

📌 About me:

I help small, medium and large businesses eliminate operational chaos, automate processes, and scale using the right IT solutions. With over 10 years of IT experience, I have moved away from the classic "web studio" format to work as a dedicated technical partner (Fractional CTO) and Lead PM. I design complex systems, manage the development process, and take responsibility for the final business result.

📌 My Expertise (Key Competencies):

✅ Architecture Design: Creating reliable solutions for B2B, SaaS, logistics, and EdTech.
✅ ERP & CRM Integrations: Developing custom management systems, deep integration of ready-made solutions, and third-party API services.
✅ Full-cycle Development Management: Coordinating IT teams from requirement gathering to successful release (complex web platforms, iOS/Android mobile apps).
✅ Digital Business Transformation: Auditing existing processes, rescue management of unfinished projects, and creating a unified digital ecosystem for the company.

📌 How I work:

I have my own cohesive full-cycle development team. With me, you get more than just scattered contractors; you get a ready-made IT department led by an experienced technical director. We take on all the technical headaches — from the initial idea to implementing tools into your company's actual workflows.

Foreign Language Website. Consultation

11 USD

I reached out to Oleksandr because I had a bunch of ideas, but I had no idea what kind of website I needed and where to even start.

In one conversation, he helped me see the strengths and weaknesses of my concept. And most importantly — he explained everything simply and to the point.
He really thinks strategically: not just “oh, do it this way,” but explains why it’s better this way and what the options are. After the consultation, I clearly understood what I needed and stopped flailing in all directions.

I want to specifically mention — Oleksandr is very generous with ideas. He doesn’t keep knowledge “to himself,” but shares everything he knows and what can be useful. This is very noticeable and very valuable.

I recommend him if you need not just a website, but a clear strategy and confidence that you are doing everything right.
