Codebase Assessment
Technical debt analysis with a prioritised, phased modernization roadmap
App Modernization
Modernise legacy applications into fast, maintainable, AI-ready systems. We analyse your existing codebase, define a phased migration plan, and re-engineer the parts that hold your business back, without a risky big-bang rewrite.

First Phase Delivery
From Legacy Constraints to Modern, Scalable Architecture
1
Codebase Assessment & Modernization Roadmap
- Dependency graph analysis and technical debt quantification
- Identify high-risk, high-reward refactoring targets
- Phased migration plan with business value per phase
- Architecture target state with migration milestones
2
Cloud-Native Re-Architecture
- Decompose monoliths into domain-aligned services or modules
- Containerise with Docker and orchestrate with Kubernetes or ECS
- Stateless service design for horizontal scaling
- Infrastructure-as-code with Terraform or CDK
3
Database & Data Layer Modernization
- Migrate from legacy databases to PostgreSQL, DynamoDB, or Snowflake
- Introduce event sourcing and CQRS patterns where beneficial
- Zero-downtime schema migrations with blue-green data strategies
- Data pipeline re-architecture for analytics and AI readiness
4
Front-End Modernization
- Migrate from jQuery, AngularJS, or legacy frameworks to React / Next.js
- Progressive replacement using micro-frontend strategies
- Performance baseline → Lighthouse 90+ target in each phase
- Design system introduction and component library build-out
5
AI Readiness Uplift
- Structured data pipeline preparation for ML model training
- API layer redesign for LLM and AI service integration
- Observability and logging standards for AI-driven features
- Vector database integration for RAG-ready data architecture
6
DevOps & CI/CD Modernization
- Migrate from manual deployments to automated CI/CD pipelines
- Introduce trunk-based development and feature flags
- Observability stack: OpenTelemetry, Datadog, or Grafana
- Security scanning and SBOM generation in the pipeline

Why Engineering Leaders Choose SpeedMVPs for Modernization
No Big-Bang Rewrites
We always take a phased approach: delivering value in each sprint while keeping the existing system live and stable.
Zero-Downtime Migrations
Blue-green deployments, strangler fig pattern, and feature flags ensure the business never stops while we modernise.
AI-First Architecture
Every modernization engagement includes an AI readiness layer, so the new system can support ML features from day one.
Quantified Technical Debt
We score debt by severity, blast radius, and remediation effort, so leadership can make evidence-based prioritisation decisions.
Team Knowledge Transfer
Documentation, architecture decision records, and live walkthroughs ensure your team fully owns the modernised system.
Measurable Outcomes
Performance benchmarks, deployment frequency, and incident rates measured before and after, so modernization ROI is visible.

App Modernization FAQ
Almost always incremental. Full rewrites carry enormous risk: the original system has years of learned behaviour encoded in edge cases that a rewrite inevitably misses. We use the strangler fig pattern: replace legacy components one by one while keeping the existing system live, then decommission legacy parts as replacements prove out in production.
The first high-value phase typically delivers in 3–8 weeks. Full modernization of a large legacy system is a 3–12 month programme depending on scope. We structure work so each phase ships something meaningful, faster API performance, a decommissioned legacy dependency, or a modernised front-end screen, so value accrues throughout, not just at the end.
Yes. We design the engagement to run in parallel with your product roadmap. Modernization work is scoped to avoid blocking feature development, using feature branches, feature flags, and integration strategies that don't require stopping the product team.
We start with characterisation tests: tests that document the existing behaviour before we change anything. This gives us a safety net to detect regressions. Documentation is produced as a deliverable of the assessment phase, not a prerequisite.
Yes. Knowledge transfer is a first-class deliverable in every modernization engagement. We run architecture walkthroughs, create architecture decision records (ADRs), and pair-programme with your engineers on the modernized components so they can extend and own the system after we leave.
