Building an in-house team takes months. Your competitors are shipping now.
- Hiring takes 4-6 months avg — that's half a year before your first sprint
- Senior devs cost €90-130k/yr in the EU — before benefits, tooling, and management overhead
- Technical debt from freelancers costs 3x to fix — shortcuts compound fast
- Missing the market window while building the team — your competitors won't wait
SaaS companies that ship within 3 months of funding close are 2.7x more likely to reach next round.
Hiring Cost vs. Outsourced Team Cost
Your product roadmap, our engineering muscle — end to end.
Custom Architecture Design
Scalable system design tailored to your domain. Microservices, event-driven, or modular monolith — we choose what fits your scale.
Team Augmentation (2-8 devs)
Plug senior engineers into your workflow. Slack, standups, your branching strategy. They feel like your team, because they work like your team.
Full-Stack Development
From React frontends to Go microservices. Production-grade code with CI/CD, test coverage, and documentation from sprint 1.
API & Integration Layer
REST, GraphQL, webhooks, third-party integrations. Clean API contracts, versioned endpoints, comprehensive documentation.
DevOps & Infrastructure
AWS, GCP, or hybrid cloud. Docker + K8s, Terraform IaC, zero-downtime deployments, monitoring and alerting from day 1.
Quality Assurance
Automated unit, integration, and E2E tests. Code reviews, static analysis, performance benchmarks. Test coverage >80% guaranteed.
From legacy codebases to production platforms — here's how we've done it.
Problem
FinTech startup stuck on a PHP monolith that couldn't handle growing transaction volume or pass compliance audits.
What we did
Migrated to Next.js microservices architecture with event sourcing, zero data loss, and zero downtime cutover.

How we measure success
Test Coverage
Guaranteed >80% on every project
Deployment Frequency
Multiple deploys per day with zero downtime
Sprint Velocity
Story points delivered per sprint, tracked transparently
From discovery to handoff in 5 transparent steps.
Discovery
Technical audit, architecture review, team composition planning. Outcome: project roadmap + architecture decision records.
1-2 weeks
Architecture
System design, tech stack selection, infrastructure planning. CI/CD pipeline and dev environment set up before sprint 1.
1-2 weeks
Build (Sprints)
2-week sprints with Friday demos. Continuous integration, automated tests, code reviews on every PR. You see progress biweekly.
8-20 weeks
QA & Hardening
End-to-end test suite, load testing, security audit, performance optimization. Test coverage >80% or we don't ship.
1-2 weeks
Handoff
Full documentation, architecture guides, runbooks, team onboarding. Your team takes over with confidence — or we stay on retainer.

Custom SaaS development — key terms and answers.
- Team Augmentation
- A model where external engineers integrate into your existing team, following your processes and tools. They work as an extension of your team, not as a separate vendor.
- Sprint-Based Development
- An agile methodology where work is organized in fixed-length iterations (typically 2 weeks). Each sprint ends with a demo and deliverable increment, ensuring continuous visibility and course correction.
- Technical Debt
- The accumulated cost of shortcuts, poor architecture decisions, and missing tests in a codebase. Like financial debt, it compounds over time and becomes increasingly expensive to address.
