Product development
Interfaces, business logic, APIs, integrations, and delivery inside one working cycle instead of isolated implementation.
Resume / Fullstack Developer
Aleksei Dergachev
Fullstack developer who carries a product from interface and business logic to API integrations and production-ready delivery.
Fullstack developer focused on real product work: interfaces, business logic, APIs, integrations, and production-ready delivery. I build solutions that simplify workflows, reduce routine work, and help products stay reliable as they grow.
Focus
Strong fullstack focus without the noise.
From idea to production
I can move from structure and interface decisions to backend logic, integrations, and launch preparation with a coherent product view.
Independent execution
Task decomposition, implementation, verification, code review, iterations, and getting the feature to a finished state.

Backend → Full-stack Developer
2024–2026
Visit product websiteDeveloped a review service for e-commerce websites as part of a small team. Joined an existing product as a backend developer, gradually took on frontend work, and went on to deliver changes across both parts of the system.
- Added features and fixed bugs across backend logic, APIs, the review widget, and the admin interface.
- Developed configurable review fields, preserving historical field names and values after a field was changed or deleted.
- Improved widget appearance and behavior settings, OAuth authentication, and notification workflows.
- As my product knowledge grew, independently turned team requests into tasks, described solutions, implemented changes, maintained statuses, scheduled sprint checks, and wrote progress reports.

Approach
How I work on a product
Product first
I look beyond the isolated task and focus on how the decision affects the full user and business flow.
Predictable architecture
I aim for a structure that can be extended and supported after the first release instead of shortcut implementations.
Frontend + backend
I can see the whole chain: interface, API, business logic, data, and integrations as one system.
Delivery
The work does not end at commit. Verification, stability, production readiness, and support matter just as much.
