Nearshore software development in Eastern Europe
BigTree108 is a nearshore software development company in Ukraine for companies in the EU, the UK, Switzerland and the Nordics: engineers who share your working day, one contract with a registered company, and the intellectual property assigned to you before anyone sees your code.
Onshore, nearshore and offshore
Onshore
A team in your own country. The easiest to meet in person, and usually the most expensive to hire, because it recruits in the same market as your own company.
Nearshore
A team in a nearby country that shares your working day. For companies in the EU, the UK and Switzerland, that is Ukraine: one to two hours ahead, on the same Monday to Friday week.
Offshore
A team several time zones away. It works when the overlap is solved by hiring people for your hours rather than by your night shift, which is how we staff teams for North America and Asia-Pacific.
Your working day, shared
Ukraine is one to two hours ahead of the UK, Ireland and Central Europe and keeps the same Monday to Friday week, so the engineers on your engagement are at work for your whole day. Planning, code reviews and an incident late in your afternoon are handled live, and nothing waits for an overnight handover.
The work runs in English, in your repositories, your tracker and your chat, and the people on it report to your lead. If part of your company works from North America or Asia-Pacific, we staff that part to its own hours; the offshore team page explains how.
What a nearshore engagement with us includes
One contract, one invoice
You sign one agreement with BIG TREE 108 LLC and receive one invoice a month. Ukrainian contracts, tax registration, declarations and payroll never reach your desk.
NDA and IP assignment before access
Every specialist has already assigned their work product to BigTree108, so the ownership chain to your company is complete on day one.
Hours you can see
Every specialist logs time in our portal, and for Upwork contracts Work Diary is the record. The same figures produce the invoice, so there is one source for both sides.
A team behind each person
Architecture review, a second pair of eyes on pull requests and cover during leave come from BigTree108, not from your budget.
Replacement from our own pipeline
Notice periods run both ways, and we hire from a pipeline we run ourselves: technical interviews by nineteen active interviewers, probation and onboarding tracked in the portal.
Written engineering rules
Tests with every change, zero warnings, security by default and everything as code. A change that breaks a rule does not merge, whoever the client is.
Three ways to work with us
Add specialists to the team you already run through dedicated developers and IT staff augmentation, hand us a project to deliver end to end, or give us a system another team wrote to take over. The outsourcing page sets out all three, and the company page covers the team and the legal identity behind them.
Engineers for every part of the product
Seventeen services, all staffed from the same team, so the backend, the app, the tests and the design are one conversation rather than four vendors.
.NET development
ASP.NET Core APIs, Azure Functions, EF Core and SQL Server from our largest engineering practice, backed by a Top Rated Plus Upwork agency. Take-overs of existing codebases welcome.
Python development
Python backends, data pipelines, AI agents and vector-database work, on AWS or Azure, delivered by engineers we hire and interview for exactly that stack.
AI development
AI development services: AI agents, AI integration of LLMs into your software, AI chatbots, AI knowledge search and RAG, document processing, voice AI agents, Microsoft Copilot and Copilot Studio, AI coding assistants, MCP servers, private LLMs and fine-tuning, and AI consulting, with dedicated AI developers or project delivery.
Front-end development
Front ends on Angular, React, Vue and Next.js: design systems, accessibility checks on every component, and end-to-end tests that run before every release.
Mobile development
Native iOS apps in Swift, cross-platform apps in .NET MAUI and React Native, built by engineers who also own the backend the app talks to.
Cloud and DevOps
Azure Functions, Azure SQL with Always Encrypted, Terraform for every resource and GitHub Actions pipelines, with drift detection and cost control built in from the start.
QA and test automation
Manual QA, test plans and automated suites in Playwright, run in continuous integration so a failing test blocks the release rather than reaching your users.
UI and UX design
Figma design systems, prototypes and interface design, handed to engineers in the same company who build them pixel-accurate and accessible.
Websites and site builders
Landing pages, business websites, corporate websites, online stores, website redesign and support, and websites for communities, public institutions, NGOs and charities, on Webflow, Framer, Wix, WordPress, Shopify and other builders, built to load fast, rank and stay editable by your own team.
ERP implementation and development
ERP implementation, development and integration for Microsoft Dynamics 365, SAP, Oracle ERP, NetSuite, Odoo and Acumatica: discovery, fit-gap, configuration, integrations, data conversion, testing, training, go-live and support, with dedicated ERP developers or project delivery.
Solutions
Custom software solutions: MVP development, SaaS development, web application development, API development and integrations, legacy modernisation, cloud migration, CRM development, Telegram and Viber bot development, chatbot development and integrations with Ukrainian services.
Design and content
Design and content services: graphic design, motion design and animation, 3D modelling and visualisation, UX research, SEO and content writing, with dedicated specialists for your team or project delivery.
Digital marketing
Digital marketing services: PPC advertising, social media marketing, email marketing, B2B lead generation and marketing automation in your own accounts, with dedicated specialists for your team or project delivery.
Research and audits
Market and competitor research, discovery and technical specification, R&D and proof of concept, code and technical audit and website audit, each ending in a written report you can act on, from the team that also builds the software.
Team roles
Project managers, business analysts, product managers, Scrum masters, technical writers, technical support, customer success and IT recruitment for software teams: full time in your team, part time or per project.
Tenders and public procurement
We are open to tenders as the supplier on Prozorro, in donor-funded programmes and from companies: websites, information systems, software support, research and audits under DK 021:2015 codes such as 72413000-8 and 72230000-6.
Dedicated team
Add engineers, QA, designers or managers from Ukraine to your team for the long run. They work your hours and process; we carry contracts, payroll and leave.

Questions about nearshore development in Ukraine
What is nearshore software development?
Nearshore software development means working with an engineering team in a nearby country, close enough that your working days overlap, rather than a team in your own country (onshore) or on the other side of the world (offshore). For companies in Europe and the UK, Ukraine is nearshore: one to two hours ahead of Western and Central Europe.
Is Ukraine nearshore for Germany, the Netherlands, the Nordics and the UK?
Yes. Ukraine is one to two hours ahead of the UK, Ireland, Germany, the Netherlands, Switzerland and the Scandinavian countries, so the whole working day overlaps. Your stand-up, your reviews and your incidents happen while the engineers are at work, not the next morning.
Can a company in the EU, the UK or Switzerland contract you directly?
Yes. BIG TREE 108 LLC signs the agreement, invoices you once a month and assigns the intellectual property to you, so Ukrainian contracts, payroll and tax filings stay with us. If you would rather keep the contract and payment protection inside a platform, the same team is available through our Upwork agency, which is Top Rated Plus with a 100% job success score.
What does nearshore software development in Ukraine cost?
We quote per engagement rather than publishing a rate card, because the stack, the seniority and the length of the engagement change the number. Write to hello@bigtree108.com with the roles or the scope and you will have a written estimate within one business day.
How quickly can a nearshore engineer or team start?
When the person is already on the team, the start is gated only by your interview and the NDA and IP assignment. When we recruit for the role, a search typically produces candidate profiles within two to three weeks, assessed by one of the nineteen active technical interviewers on the team.
Do your engineers work in English?
Yes. Every engagement runs in English end to end: interviews, stand-ups, pull request reviews, written plans and documentation.
Who owns the code and the intellectual property?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward, so the chain of ownership is complete before any access is granted.
