Offshore software development team on your hours
BigTree108 runs offshore development teams from Ukraine for companies in North America, Australia, New Zealand, the Middle East and Asia. The engineers are staffed to your working hours, Pacific included, they work for a registered company under one contract, and the intellectual property is assigned to you before anyone sees your code.
Offshore without the overnight handover
The usual objection to an offshore team is the time difference: a question asked in your afternoon is answered the next morning, and a production incident waits for someone to wake up. We remove it when we staff the engagement. The people on your team are assigned or recruited to work your schedule, so they are online during your day and the overlap is not yours to manage.
For companies in the EU, the UK and Switzerland the same team is nearshore rather than offshore; the nearshore development page covers that case.
How the hours work, by region
United States and Canada
Engineers assigned or recruited to your schedule, Eastern to Pacific, so stand-ups, reviews and incidents happen live during your day.
Australia and New Zealand
The same approach: the people on your engagement work your day, and we recruit for those hours when the role needs it.
Middle East and Israel
Working hours in Ukraine already overlap with most of your day, so the team runs alongside yours without a shifted schedule.
Japan, Korea and Singapore
Five to seven hours ahead of Ukraine. We staff the overlap the way we do for North America: people who work your schedule.
What an offshore 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.
Choose how the team works with you
Bring one engineer or several into the team you already lead through dedicated developers and IT staff augmentation, have us deliver a project end to end with our own lead, or hand over a system another team wrote. The outsourcing page compares the three, and the company page covers who we are and how to check our registration before you sign.
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 offshore development in Ukraine
What is an offshore software development team?
An offshore development team is a group of engineers in another country, usually several time zones away, who build and maintain your software under a contract with their employer. BigTree108 runs offshore teams from Ukraine for companies in North America, Australia, New Zealand, the Middle East and Asia, staffed to work your hours.
How do you cover US, Canadian or Australian working hours from Ukraine?
We treat time zone as a hiring and scheduling requirement. The people on your engagement are assigned or recruited to work your schedule, Pacific included, so your stand-up, your reviews and your incidents are handled live rather than the next morning. You should not be the one adjusting.
Can a company outside Europe contract a Ukrainian company 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 an offshore development team 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.
Which roles can an offshore team include?
.NET and Python back-end engineers, Angular, React and Vue front-end developers, iOS, .NET MAUI and React Native mobile developers, QA and test automation engineers, cloud and DevOps engineers, designers, business analysts and project managers, from one company under one contract.
How do you keep quality high when the team is offshore?
With written engineering rules that every change is reviewed against: tests ship with the feature, the build ends with zero warnings, security is deny-by-default and everything from infrastructure to DNS is code. Architecture review and a second pair of eyes on pull requests come from BigTree108, not from your budget.
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.
