Complexity Solution Group

Complexity Solution Group is a small IT services team based in Ukraine, working with clients internationally, including organizations in the UK and the US. Its case studies span HR management platforms, professional social networking tools, and CRM systems built for AR/VR-based education, indicating experience with SaaS products, business-management software, and platforms requiring both consumer-facing design and backend complexity. The team size is small (1-10), positioning it for focused, hands-on project delivery rather than large-scale account management. The agency's declared service list covers Search Engine Optimization, API Development, Blockchain, Custom Software Development, E-Commerce Development, Mobile App Development, IT Consulting, and UX/UI Design, though its documented project work centers on full-stack software engineering. Described technical work includes backend development with Python frameworks such as FastAPI and Django (with DRF and Django Channels), databases including PostgreSQL, MongoDB and Redis, and infrastructure built on Docker, AWS, Nginx, and CI/CD pipelines via GitHub Actions. Frontend delivery relies on JavaScript, React, Next.js and TypeScript, with design work carried out in Figma and project coordination tracked through Jira. Project workflows are described as covering discovery, backend and frontend development, design, and in some cases QA using manual and automated testing (Playwright). The agency also lists internally developed products, an iOS alarm app and an AI document tool, alongside its client project history.
