Product engineering services that modernize and scale.
Architecture cleanup, performance optimization, stack migration, and feature expansion - without the big-bang rewrite.
Modernization pipeline
Six phases that take legacy systems from assessment to production cutover - with zero downtime.
- 01
System Audit
Assess architecture, dependencies, tech debt, and risks
- 02
Migration Plan
Design target architecture and phased migration strategy
- 03
Data Migration
Move databases with zero downtime and data integrity
- 04
Code Modernization
Refactor, rewrite, or wrap legacy components
- 05
Testing & Validation
Comprehensive testing at every migration stage
- 06
Cutover & Monitor
Controlled switch with rollback capability
System Audit
We begin with a comprehensive audit - static analysis surfaces code quality issues, dependency scans reveal vulnerabilities, load tests expose performance ceilings, and code review identifies architectural patterns that block scaling.
- Static Analysis
- Dependency Audit
- Load Tests
- Code Review
Migration Plan
The audit findings drive a target architecture design and a phased migration roadmap. Risk matrices prioritize what to modernize first, milestone planning ensures measurable progress, and architecture diagrams align all stakeholders.

- Milestone Planning
- ADRs
Data Migration
Database migrations run without service interruption - dual-write patterns keep both old and new systems in sync, shadow reads validate correctness, and automated verification ensures zero data loss throughout the process.
- pg_dump
- Flyway
- Dual-Write
- Shadow Reads
Code Modernization
The strangler fig pattern lets us replace legacy components incrementally - wrapping old APIs, extracting micro-frontends, and modularizing monoliths without a risky big-bang rewrite. Each piece is validated independently.
- Strangler Fig
- API Wrapping
- Micro-Frontend
- Modularization
Testing & Validation
Every migration step is gated by automated testing - end-to-end tests verify user flows, regression suites catch regressions, canary deployments limit blast radius, and A/B comparisons prove the new system matches or beats the old.
- E2E Tests
- Regression Suite
- Canary Deploy
- A/B Compare
Cutover & Monitor
The final cutover uses blue-green deployment with instant rollback capability. Feature flags control the rollout percentage, comprehensive monitoring tracks error rates and latency, and runbooks define escalation procedures.

What we deliver
From monolith decomposition to full stack migration - we modernize systems that other teams are afraid to touch.
Legacy Modernization
Move from outdated stacks to modern frameworks - incrementally, without halting operations or losing data.
Architecture Re-Design
Monolith to microservices, clean architecture, service boundaries, and domain-driven decomposition.
Performance Optimization
Query tuning, caching strategies, bundle optimization, lazy loading, and infrastructure right-sizing.
Stack Migration
Language, framework, database, and cloud platform migrations with phased rollout and rollback plans.
Technical Debt Reduction
Systematic refactoring, test coverage improvement, dependency updates, and documentation overhaul.
Feature Expansion
Add new capabilities to established products while preserving stability and backward compatibility.
Technology stack
We work across legacy and modern stacks - meeting your system where it is and migrating it where it needs to go.
