Software Built Under Pressure.
Delivered Without Compromise.
Underfire Labs assembles product squads from a deep network of senior Ukrainian engineers — mobile, frontend, backend, machine learning, AI agents, QA, design and SEO. Tell us the outcome you need; we put together the exact team that ships it.
There is no "we don't do that" here. Every direction below is covered by engineers who have shipped it in production — and if a project needs a rare skill, our network reaches further than any single office ever could.
Native and cross-platform apps: fintech, health, marketplaces, streaming, offline-first field tools.
Dashboards, SaaS platforms, marketing sites and design systems that stay fast under real traffic.
APIs, event pipelines, payments, multi-tenant architecture, migrations off legacy systems.
Recommendations, forecasting, computer vision, document understanding, MLOps and monitoring.
Autonomous agents, RAG systems, tool-calling workflows and copilots wired into real business processes.
Product design, manual and automated testing, release pipelines, technical SEO and analytics.
Underfire Labs runs on a vetted network of engineers across Kyiv, Lviv, Dnipro, Odesa and Kharkiv — plus Ukrainian specialists now working from across Europe. Fifteen people form our core team; behind them stand dozens more we have shipped with before.
Mobile, web, backend, ML, AI agents, QA, design, SEO, DevOps. We staff a role in days, not months, because the people are already known to us.
Our teams have shipped through blackouts, air raids and impossible deadlines. Resilience is not a slide in our deck — it is how we learned to work.
Every engineer we place has 5+ years of production experience and passes a live technical screen with our CTO before touching your codebase.
Ukrainian time zone covers a full European day and a solid US-East morning. Daily written updates, demos every Friday, no black boxes.
Repos, cloud accounts and infrastructure stay in your name. NDAs, DPAs and clean IP assignment signed before the first commit.
Start with one engineer for discovery, grow to a twelve-person program, shrink to maintenance. Monthly notice, no lock-in contracts.
Platforms, apps and internal tools we designed, built and still maintain. Full write-ups on the products page.
Cross-platform wellness app with offline sync, HealthKit integration and an on-device coaching model. 180k installs in year one.
LLM agents that resolve tier-1 support tickets end to end, with tool access, guardrails and a human handoff path.
Multi-currency ledger, reconciliation engine and admin console processing eight-figure monthly volume.
45 minutes with our CTO, not a salesperson. We map the outcome, constraints, deadline and the riskiest unknown.
Within 72 hours you get named engineers, their profiles, a delivery plan, a fixed rate card and a realistic timeline.
We ship something real and demoable in the first fortnight — architecture spike, working slice or prototype. You judge us on output.
Weekly releases, CI from day one, QA in the loop, written daily updates and a Friday demo. Your PM or ours.
Documentation, runbooks and knowledge transfer — or we stay on as your product team. Both paths are first-class.
Send a brief — even a rough one. You will get a written response within one business day and a scoping call slot with our CTO.
