Transparent terms on every project

We agree on cost, code ownership and support before work begins — no surprises along the way.

Personal manager

One point of contact for all your tasks. The manager understands your business, takes new requests and runs them with the team — you don’t have to coordinate anyone.

A team for your stack

We assemble specialists for the technologies and tasks of your particular project, and change the lineup along the way if the task calls for other skills.

Fixed estimate

We estimate the project by stages and fix the cost in the contract. The budget does not change without your approval.

Results every 2 weeks

We work in sprints and show finished functionality at every demo. You see real progress, not reports about it.

The code and rights are yours

We work under a contract and NDA. We hand over the copyright, source code, repository and all access — the product fully belongs to you.

Warranty and support

We respond to requests within an hour and agree on fix timelines based on complexity. The warranty period is set in the contract for each project.

What we build

Full cycle — from design and architecture to launch and scaling.

Web development

High-load web applications, portals and SaaS platforms built with React, Next.js and Vue.

Mobile

iOS, Android and cross-platform apps with Flutter and React Native on a single codebase.

Backend & API

Microservices, REST/GraphQL and reliable integrations on Node.js, Go, Python and Java.

AI & ML

LLM integration, chatbots, recommendation systems and process automation.

DevOps & Cloud

CI/CD, Kubernetes, infrastructure on AWS, GCP and regional clouds. Stability under load.

UX/UI Design

We research user scenarios and design prototypes and design systems that make the product easy to grow.

Different stacks for different tasks

We are technology-neutral: we choose the tool that best solves your specific problem.

How we work

A clear path from the first call to a working product.

01

Business analysis

We dig into your business: goals, processes, users and constraints. We define what problem the product must solve, capture the requirements in a specification and prepare a stage-by-stage estimate.

02

Design and architecture

We design the interfaces and technical architecture with load, security and future growth in mind. Only what you have approved goes into development.

03

Development

We work in two-week sprints and show finished functionality after each one. The code goes through code review and testing.

04

Launch and support

We release the product to production, set up monitoring and hand over the code and all access to you. After that — a warranty period and SLA-based support.

OneLink or a random freelancer

A scattered team

  • You coordinate contractors yourself and explain the task to each of them
  • One stack — the task gets bent to fit it
  • Deadlines are “whenever it works out”
  • They disappear after payment
  • No testing or documentation
  • No support after handover

OneLink

  • You only talk to your personal manager — your digital concierge
  • Senior engineers manage and coordinate a team assembled for your stack
  • Estimate fixed in the contract and 2-week sprints
  • Contract, NDA and a dedicated manager
  • Tests, code review and documentation
  • Warranty and a response to requests within an hour

We take responsibility for all of the above and put it in the contract.
