Rollback Safety:Dual-Write Bi-Directional Sync
MIGRATION PIPELINE

How we modernize enterprise systems safely.

01

Architectural Audit & Dependency Mapping

Audit legacy database locks, undocumented APIs, and system bottlenecks to define the extraction boundary.

02

Facade Gateway Deployment

Deploy an intelligent proxy in front of the legacy application to enable route-by-route shadow routing.

03

Domain Slice Extraction

Re-engineer high-traffic service slices in clean modern microservices with automated unit & integration suites.

04

Cutover & Legacy Retirement

Gradually shift 100% of live traffic to the modern system and cleanly decommission legacy server nodes.

CAPABILITIES

Unlock team velocity and eliminate technical debt.

Incremental MigrationTraefik, Envoy, AWS API Gateway, EventBridge

Strangler Fig Pattern Microservices Migration

Deconstruct legacy monoliths incrementally behind dynamic API gateways without a single minute of customer downtime or high-risk big-bang rewrites.

Database ModernizationDebezium, Kafka CDC, AWS DMS, pglogical

Zero-Downtime Database Schema Refactoring

Migrate legacy MySQL / Oracle / MS SQL monolith databases to cloud-native PostgreSQL / Aurora with continuous real-time CDC replication and rollback safety.

API ModernizationtRPC, GraphQL Yoga, Zod, Redis Cache

Legacy REST to Type-Safe GraphQL & tRPC

Wrap undocumented legacy endpoints in strictly typed schemas with automated validation and sub-5ms caching layers.

Frontend Re-PlatformingNext.js 15, TypeScript, React 19, Tailwind

Automated Codebase Porting to Modern TypeScript

Migrate legacy jQuery, PHP, or AngularJS codebases to modern Next.js 15 App Router architecture with full test harness preservation.
