Challenge

[Created full technical solution for NextDoorDrivingn company from the scratch, addressing scalability and integration needs.]

Solution

[Base project was developed by Vue/Nuxt from frontend and Parse platform/Node.js as backend API. MongoDB database was selected as initial data storage. Next when the company growes up, we scaled the solution to meet the increasing demands. Moved landing pages from Nuzt to Astro to meet best SEO requirements. Moved main student's and client's dashboard from vue to react.js. Database was updated from MongoDB to PorgeSQL. Ios application was developed with React Native tools]

Process

Predictable delivery, no surprises.

  1. Brief & discoveryA call to understand scope, constraints and your client’s expectations. NDA signed first.
  2. Architecture & estimateTechnical design, risks, timeline and a transparent estimate you can pass on to your client.
  3. Iterative buildShort sprints, weekly demos, code reviews and automated tests. You always see working software.
  4. Launch & handoverDeployment, documentation, knowledge transfer and a support window after release.

Leadership

One accountable lead. Zero overhead.

Every project is led by Alex Sinkevych, a system architect and team leader with more than 20 years of hands-on experience. The person who designs the system owns the technical direction, talks to you, and makes sure the team delivers — while a dedicated project manager keeps schedule and communication on track.

  • Architecture decisions made by someone who has shipped and maintained large systems
  • Honest estimates and early warnings, not late excuses
  • Direct line to the decision-maker — no account-manager layers
  • Senior full-stack and backend developers who work in the Node/React ecosystem every day

The team

A compact senior team, led by an architect.

Architecture, project management, full-stack and backend engineering, and design under one roof — so you work with a single, self-sufficient team.

FAQ

Questions partners usually ask.

Can you work under our brand?

Yes. White-label is our default mode for agencies. We use your communication channels, your naming and your reporting format, and we sign an NDA before discussing any project details.

Who owns the code and IP?

You or your client. All intellectual property is assigned on payment, and we are happy to work in your repositories from day one.

How do you handle time zones and communication?

We agree on overlapping working hours up front, run weekly demos and short written updates, and use whatever tools you prefer — Slack, Teams, Jira, Linear and so on.

What is the minimum engagement?

We take on both small fixed-scope projects and long-term team engagements. Tell us what you need and we will propose the right format.

Can you take over an existing codebase?

Yes. We start with a short technical audit, agree on priorities and then stabilise, refactor or extend the product as needed.
