Modernization & Managed Engineering

Re-platform, re-architect and keep shipping, with a team that runs the product after launch.

Overview

Legacy systems are usually legacy because they worked: they made money, ran the business and outlived the people who built them. Modernizing them is a matter of respect and risk management. We re-platform, re-architect and rewrite incrementally, so the business never stops and every step delivers something usable.

Our modernization work is grounded in a clear-eyed assessment of what to keep, what to replace and in which order, with the data migration, integration and testing that make the difference between a clean cutover and a very long weekend.

This page also covers the managed engineering and support that keeps a modernized product running after launch.

Product and legacy modernization

Legacy systems are usually legacy because they worked. We re-platform, re-architect and rewrite incrementally, so the business never stops.

Modernization assessment

Codebase, architecture, data and dependency review with a prioritized, risk-rated plan.

Re-platforming

Moving applications to cloud infrastructure and managed services with minimal code change.

Re-architecture

Decomposing monoliths, introducing APIs and services, modernizing data access.

Incremental rewrite

Strangler patterns that replace functionality piece by piece behind stable interfaces.

Typical use

  • Products on unsupported frameworks or languages that are hard to hire for
  • Monoliths that make every release risky and slow
  • On-premises applications moving to cloud

Offering 2

Managed engineering and support

Products in production need steady hands: features that keep coming, bugs fixed quickly, dependencies kept current and incidents handled with clear service levels.

Ongoing feature development

A steady cadence of enhancements prioritized with your product owner.

Maintenance and upgrades

Dependency updates, platform upgrades, security patches and technical debt reduction.

Production support

Incident response, root-cause analysis and communication with agreed service levels.

Monitoring and reliability

Observability, alerting and SLOs that catch issues before users report them.

Typical use

  • Products whose original team has moved on or been reassigned
  • SaaS companies that want engineering capacity without growing headcount
  • Enterprises with business-critical custom applications and no in-house team
