The challenge
A North American enterprise technology firm was mid-way through a multi-year modernisation programme — migrating a legacy .NET Framework monolith to a microservice architecture on Azure. Their internal team had the architecture expertise but was under-resourced for the volume of development work required to hit delivery milestones.
They needed senior engineers who could join actively running sprints without a learning curve, understand enterprise-grade codebases, and operate within existing Azure DevOps workflows and code review standards.
How we staffed it
KometCode placed three engineers into the client’s existing team structure:
- Senior Full-Stack Developer (.NET Core / Angular) — feature delivery across the API layer and Angular front-end
- Backend Engineer (Microservices / PostgreSQL) — service decomposition, API gateway integration, and database migration from SQL Server to PostgreSQL
- QA Engineer (Automation) — Playwright-based end-to-end test suite, integrated into Azure DevOps CI/CD pipeline
All three engineers worked within the client’s tools (Azure DevOps, Teams, GitHub Enterprise) and time zone overlap (4-hour daily overlap with North American EST). No process changes were required on the client side.
The engagement structure
The engagement ran for 14 months across three phases:
Months 1–4: Initial sprint integration Engineers joined existing scrum teams. The first sprint delivery was on day 10 — well within the client’s 2-week target for new team members. Code review standards, branching conventions, and deployment procedures were matched from the first week.
Months 5–10: Accelerated delivery The team took on increased ownership of two microservices — the Order Management and Notification services — from design through to production deployment. This freed the client’s senior architects to focus on cross-service concerns.
Months 11–14: Knowledge transfer and scale-down As internal hiring caught up, the KometCode team progressively handed back ownership, documenting service architecture and running pair-programming sessions with incoming internal developers.
Technical highlights
- Decomposed 3 legacy modules from the .NET Framework monolith into independently deployable microservices
- Migrated 12 million records from SQL Server to PostgreSQL with zero data loss and a 2-hour downtime window
- Built Playwright test suite covering 340+ end-to-end scenarios, reducing regression test time from 6 hours (manual) to 22 minutes (automated)
- Reduced Azure infrastructure cost by 18% through right-sizing and autoscaling configuration
Results
- All delivery milestones met across the 14-month engagement — no slippage attributable to the augmented team
- Zero ramp-up cost — first sprint delivery within 10 days of onboarding
- Smooth scale-down — structured knowledge transfer meant no institutional knowledge was lost when the engagement concluded
- Client extended the original 6-month scope to 14 months based on delivery quality
