Software Modernisation Without Big-Bang Risk.
De-risk outdated codebases, eliminate fragile technical debt, and migrate legacy monoliths to modern, high-performance cloud architectures through staged 2-week sprints with guaranteed zero downtime.
Free 30-minute call. Written plan within 5 working days.
Engineered to Replace Technical Debt Safely
Every module is extracted using proven architectural patterns that maintain active business operations while systematically replacing fragile code.
Legacy Codebase & Architecture Audit
Static code analysis, dependency vulnerability scanning, and reverse-engineering undocumented domain logic into clean technical specifications.
Strangler Fig Pattern Extraction
Incremental decoupling of monolithic domains behind a reverse-proxy gateway, replacing outdated services piece-by-piece with zero disruption.
Relational Database & Schema Modernisation
Migrating legacy SQL Server, Oracle, or MySQL schemas to PostgreSQL with zero-data-loss dual-write pipelines and schema normalization.
REST & GraphQL API Facade Layer
Wrapping legacy core systems in high-throughput, type-safe API gateways to cleanly power modern web apps, mobile clients, and partner integrations.
Frontend & User Interface Overhaul
Replacing slow, non-responsive ASP.NET, PHP, or JSP interfaces with fast, responsive Next.js App Router applications with sub-second page loads.
Docker Containerisation & Cloud Migration
Packaging fragile bare-metal legacy workloads into reproducible Docker containers and deploying to AWS, Google Cloud, or Azure with auto-scaling.
Shadow Traffic & Parity Verification
Replaying production read requests simultaneously against legacy and modern services to prove byte-for-byte behavioral accuracy before cutover.
Zero-Downtime Cutover & Rollback Runbooks
Blue-green traffic shifting, canary rollouts, and scripted instant fallback runbooks ensuring business continuity throughout deployment.
Fixed 2-Week Sprints With Continuous Verification
We avoid high-risk "big-bang" rewrites. Each sprint deploys tested, functioning capabilities to a live staging environment with measurable progress.
Architecture Audit, Parity Harness & Facade
Deep inspection of legacy codebase, establishing automated regression tests, and deploying the initial API proxy facade to isolate customer-facing traffic.
Database Refactoring & Dual-Write Sync
Modern schema design in PostgreSQL, deploying bidirectional data synchronization pipelines, and verifying zero-loss data replication under live traffic.
Core Domain Extraction & Modern Interface
Rebuilding high-priority business logic in TypeScript/Node.js micro-modules and deploying the modern responsive Next.js frontend to internal staging.
Shadow Traffic Testing & Live Canary Cutover
Mirroring live production load through shadow traffic testing, executing graduated traffic shifting, and completing final production cutover.
Chosen for Maintainability, Speed, and Zero Lock-In
We migrate legacy stacks to modern open standards that your existing or future in-house engineers can easily hire for and maintain.
Server-side rendering, sub-second route transitions, and strict end-to-end typing replacing brittle template engines.
Rock-solid ACID compliance, JSONB document flexibility, and automated schema migrations replacing locked stored procedures.
Lightweight, high-concurrency event handling replacing memory-heavy monolithic application servers.
Reproducible container images eliminating "works on my machine" bugs and enabling seamless AWS/Azure multi-region hosting.
Asynchronous job processing, distributed locks, and sub-millisecond session caching for high-load workflows.
Automated linting, unit test suites, security scans, and staging preview builds on every single pull request.
