Tech Lead

Personal Expertise
+ Team Power

I personally handle the entire technical part of projects — from defining technical requirements and system architecture to writing code, integrations, testing, and product launch.
I do not outsource development and do not work as a studio. This means you always communicate directly with the person who actually designs the system, writes the code, and takes full responsibility for the result.

When needed, I involve a trusted team of specialists:
UI/UX Designer — for a thoughtful and user-friendly interface
SMM Specialist — for content creation and social media management
Targeting Specialist — for launching and optimizing advertising campaigns
👉 The team is involved only if it is truly necessary for your project.
You don’t overpay for unnecessary services — only for what brings real value.

My approach to work:

Help with defining technical requirements
Personal responsibility for the project
Transparent payment system
Meeting agreed deadlines
Full process documentation
Post-launch support
All access rights and ownership belong to you
Clear and future-proof architecture
