Who we help

B2B SaaS and operations-heavy software teams with aging product foundations.

Ideal teams

  • B2B SaaS product teams
  • Internal operations product owners
  • SMB software products scaling fast
  • Companies with aging Java/Spring backends
  • Teams with weak admin UX and slow internal workflows

Problems we solve

  • High-risk release cycles caused by legacy code coupling
  • Admin portals that block internal operations instead of helping
  • Unclear API contracts that create integration regressions
  • Rewrite pressure when staged migration is possible
  • Poor maintainability and onboarding friction for engineering teams

Services

Three focused modernization offers.

Spring Boot modernization

Upgrade legacy Java and Spring Boot services, reduce release risk, and stage migration without a full rewrite.

Case studies

Recent modernization outcomes.

B2B SaaS billing platform modernization

Anonymized UK SaaS company

Problem

Monolith release windows and tightly coupled integrations caused frequent hotfix cycles.

What changed

Upgraded Spring Boot versions, isolated integration boundaries, and shipped phased module refactors.

Outcome

Release cycle reduced from monthly to weekly with fewer production incidents.

Stack: Java, Spring Boot, PostgreSQL, React | Timeline: 12 weeks

Release cadence: 4x faster Production incidents: -42%

Internal operations portal redesign

Anonymized EU software team

Problem

Operational teams relied on manual workarounds due to unclear UI and unstable APIs.

What changed

Introduced role-based React admin workflows, API contract cleanup, and QA checklists.

Outcome

Ops teams completed critical tasks faster with fewer support escalations.

Stack: React, TypeScript, Spring Boot APIs | Timeline: 10 weeks

Task completion time: -33% Support tickets: -29%

Portfolio clarity

Client work and labs are separated clearly.

Client work

Process

How engagements run.

Step 1

Audit

Current architecture, pain points, and delivery risks are mapped before any build work starts.

Step 2

Scope

Prioritized modernization scope, acceptance criteria, and migration boundaries are documented.

Step 3

Sprint

Changes are delivered in controlled sprint slices with regular demos and shared visibility.

Step 4

QA and handover

Regression checks, deployment notes, and maintainability guidance are transferred to your team.

Step 5

Optional retainer

Post-delivery support is available for planned upgrades, cleanup cycles, and technical reviews.

Founder credibility

FAQ

Common modernization questions.

Do you replace our entire system?

No. We focus on staged modernization so you can improve architecture without risky full rewrites.

What stacks do you typically work with?

Java, Spring Boot, React, TypeScript, and API-heavy B2B SaaS products with aging backends or admin portals.

How do you start a project?

Every engagement starts with a modernization audit, then scope, sprint planning, QA/handover, and optional retainer support.

Can you work with UK, EU, and US teams remotely?

Yes. Delivery is remote-first with planned overlap windows, clear sprint updates, and documented handovers.
