Legacy Modernization Company that ships without breaking the business.
Application modernization services from an India-based senior engineering team - legacy system modernization, software replatforming, API modernization and zero-downtime cloud migration, delivered in vertical slices with strangler-fig cutovers.

zero-downtime
Six capabilities. One modernization programme.
From the first code audit to the final decommission - one accountable team across architecture, engineering and operations.
Legacy assessment
Codebase archaeology, dependency mapping, risk scoring and a target-state architecture grounded in real business outcomes.
- Code & data inventory
- Risk heatmap
- Target architecture
Application reengineering
Rewriting and refactoring monoliths into modular services, modern frameworks and maintainable codebases your team can own.
- Modular decomposition
- Modern stack
- Test coverage
API enablement
Exposing legacy systems through clean APIs, event streams and integration layers so new products can ship without touching old code.
- REST & GraphQL
- Event streams
- Anti-corruption layers
Cloud migration
Replatforming and refactoring workloads to AWS, Azure or GCP with landing zones, IaC and FinOps from day one.
- 6R strategy
- Landing zone
- FinOps baseline
Data migration
Zero-downtime database moves, schema evolution, CDC-based replication and reconciliation that auditors can sign off on.
- CDC replication
- Reconciliation
- Schema evolution
Zero-downtime cutover
Strangler-fig patterns, dark launches, traffic shifting and rollback gates so users never feel the migration happening.
- Strangler-fig
- Traffic shifting
- Rollback gates
From audit to safe cutover.
A four-step approach that turns legacy risk into modernized platforms - one verifiable slice at a time.
Discover & score
Audit the codebase, infrastructure, data and dependencies. Score risk, business value and effort to build the modernization roadmap.
Decompose & design
Carve out bounded contexts, define seams, design the target architecture and select the right pattern - rehost, replatform or rebuild.
Migrate in slices
Ship vertical slices behind feature flags, route traffic gradually with strangler-fig patterns and reconcile data continuously.
Decommission & optimise
Retire legacy systems safely, capture runbooks, tune for cost and performance, and hand over with full documentation.
What good modernization looks like.
Real numbers from real programmes - the cost reduction, velocity and reliability lift our clients hold us to.
Pragmatic choices. Auditor-friendly.
We meet your legacy where it lives - and pick targets your team can hire for, operate safely and audit later.

Modernization programmes already shipped in your industry.
We bring playbooks for regulated cutovers, reconciliation reports and integration patterns from every vertical we operate in.
Banking & insurance
Core banking, policy admin and ledger migrations with auditor-ready reconciliation and zero customer impact.
Healthcare
EHR, claims and patient-portal modernization with HIPAA-aware data flows and clinical continuity guarantees.
Retail & supply chain
OMS, WMS and ERP cutovers with peak-season-safe rollouts and full traceability across channels.
Industrial & B2B SaaS
Monolith-to-service decomposition for multi-tenant SaaS and industrial platforms with stable APIs throughout.
Quiet cutovers. Loud impact.
No re-platforming theatre, no big-bang releases, no war rooms - just engineering that respects the system you have built.
Zero-downtime by default
Strangler-fig, dual-write and traffic shifting are how we ship - not a stretch goal. Users never feel the cutover.
We own the risk register
Every migration ships with a live risk log, rollback plan and pre-agreed abort criteria. No heroic war rooms.
Slices, not big-bangs
We carve legacy systems into vertical slices and ship one at a time. Value lands in weeks, not multi-year programmes.
Modernization that pays back
Every roadmap maps to a TCO model and a velocity target. We measure the payback, not just the rewrite.
“A 14-year-old monolith, replaced without a single outage.”
SyncTrix took the riskiest system in our estate and shipped it in slices. Reconciliation reports landed in our auditor’s inbox every week, traffic shifted in 5% increments, and the old stack was retired without a single rollback. The board stopped worrying about modernization.
Questions we hear from CTOs and architects.
Have a different one? We are happy to walk you through approach, risk plans and references on a call.
