Our Methodology

We use proven migration patterns to minimize risk and ensure business continuity throughout the modernization process.

01 — Assessment

We map your codebase and identify risk.

You get a migration roadmap — yours to keep.

02 — Proof of Concept

We migrate one module, live, in parallel.

You see it work before committing.

03 — Strangler Fig Migration

Module by module. Your team keeps shipping.

Zero downtime.

04 — Deployment & Handover

Final cutover, docs, knowledge transfer.

You own it fully from day one.

Your teamkeeps shipping throughout

What we replace

Modernization Stack

Your customers depend on software built a decade ago. We migrate it — without taking your operations offline.

⬡01

Today

COBOL & Java EE monoliths

↓

After

Domain-driven microservices

We decompose tightly coupled legacy systems into independently deployable services — preserving business logic while eliminating technical debt.

◈02

Today

Aging backend infrastructure

↓

After

Cloud-native APIs & runtimes

From on-premise servers to containerized, observable backends your team can actually maintain and scale on demand.

⬟03

Today

Server-rendered or jQuery UIs

↓

After

Component-based frontends

We migrate to React or Svelte — giving your B2B users a faster, more consistent interface across every device.

Success Story

Legacy Application → Modern Microservices

Challenge

The Challenge

A mission-critical monolith handled millions of daily transactions but had brittle releases, slow recovery times, and significant operational overhead — leaving the business unable to ship new features without risking outages.

Solution

Our Approach

We ran a risk-first, phased migration using the Strangler Fig pattern: isolating and extracting payment reconciliation, transaction processing, and reporting into independent modern services on Kubernetes. This approach preserved availability, reduced operational toil, and enabled continuous delivery of new capabilities.

Results

Key Outcomes

✓65% reduction in infrastructure costs

✓10x faster deployments

✓40% performance improvement

✓Zero downtime

FAQ

It depends on the size and complexity of your system. A typical engagement runs between 3 and 18 months. We always start with a 1–2 week assessment that gives you a precise roadmap and timeline before any commitment to the full migration.

No. The Strangler Fig approach is specifically designed so your team keeps shipping features on the existing system while we work in parallel. There is no freeze period and no big-bang cutover.

Yes — and we encourage it. The assessment is a standalone deliverable. You get a written migration roadmap you own regardless of whether you continue working with us. Many clients use it to build internal alignment before committing to a full engagement.

We work on a time-and-materials basis with a fixed monthly rate. No surprise invoices. The assessment phase has a fixed price so you know exactly what you are committing to upfront.

We reply within one business day. If there is a fit, we schedule a 30-minute discovery call — no pitch, just a technical conversation to understand your situation. From there we propose a scoped assessment.
