Modernize critical systems without reckless total rewrites.
Total rewrites kill companies. We apply surgical strangler-fig migrations, targeted schema refactoring, and performance hardening to evolving production systems—protecting uptime, revenue, and developer velocity while systematically paying down tech debt.
Instant rollback
Rollback path per cutover
Bit-for-bit
Shadow Run Validation
None
Customer-Facing Downtime
Index and connection-pool tuning, driven by real query plans.
Migrations are rehearsed against a copy of production before they run.
- Strangler Pattern: The monolith keeps serving while new services take over, one domain at a time.
- Shadow Writes: Every write is duplicated and compared before the new service goes live.
- Reversible Cutovers: Rollback is a configuration switch, rehearsed before cutover day.
Symptoms of systems carrying unaddressed debt.
Code rot is rarely a sudden crash. It is an insidious erosion of shipping confidence, database stability, and engineer morale.
Deployment Paralysis
Shipping a two-line hotfix needs emergency coordination, a manual test checklist, and a tense observation window. Without reliable regression tests, a change in one subsystem surfaces as silent breakage somewhere else.
Lock Contention & N+1 Storms
Unindexed tables that have outgrown their queries, nested ORM loops, and unbounded audit logs consume connection pool capacity. Traffic spikes lock core transactions, and the timeouts cascade into background workers.
Fragile Third-Party Webhooks
Payment gateways, ERP syncs, and vendor APIs are called synchronously inside user requests. A brief hiccup upstream surfaces as a customer-facing timeout in your product.
Onboarding Friction & Senior Attrition
Setting up a local development environment means following tribal knowledge through manual steps nobody has written down. Senior contributors spend their energy untangling circular dependencies instead of shipping product.
A disciplined 5-step engineering framework.
We do not tear down the plane while it is carrying passengers. We wrap the legacy core, extract domain services incrementally, verify behavior via shadow traffic, and systematically decommission obsolete code.
Where we apply surgical interventions.
Database & Schema Refactoring
Zero-downtime column migrations, indexing strategy overhauls, partitioning multi-gigabyte audit logs, and eliminating N+1 ORM overhead.
- • Online DDL & pg_repack
- • Connection poolers (PgBouncer)
- • Read replica segregation
Cloud & Container Modernization
Migrating pets to cattle. Unifying fragmented custom EC2 setups into clean containerized ECS/Kubernetes or serverless runtimes.
- • Declarative Terraform IaC
- • Ephemeral preview environments
- • Horizontal autoscaling
Frontend Decoupling
Extracting tangled server-rendered templates and jQuery spaghetti into high-speed, typed Next.js applications with design system integrity.
- • Micro-frontend micro-apps
- • Unified design tokens
- • Strict TypeScript contracts
CI/CD & Automated Testing
Replacing manual verification procedures with automated GitHub Actions workflows that run on every change, with no tolerance for flaky tests.
- • Playwright smoke suites
- • Deterministic database seeders
- • Automated canary releases
Why we almost never recommend starting from scratch.
Legacy software is not simply old code. It represents years of hard-won edge cases, unwritten regulatory workarounds, and implicit customer tolerances that nobody documented.
Declaring a complete rewrite usually means 12 to 18 months of silent progress with no commercial value delivered. We respect the existing business and modernize incrementally without gambling your balance sheet.
The Reckless Total Rewrite
A parallel engineering initiative that locks senior talent away from customer requirements for a year or more.
- 12–18 months in the dark with zero customer features shipped
- High chance of scope explosion and project cancellation
- Massive cutover day with catastrophic unexpected edge-case regressions
- Forces two distinct teams into adversarial political competition
Incremental Strangler Refactoring
Surgical extractions around clear domain seams, releasing verified value into production every 2 weeks.
- Continuous value shipped to real production users every sprint
- Zero revenue interruption; automatic instantaneous fallback routing
- Shadow traffic verifies functional parity before the full switch
- Empowers existing engineering teams through pair programming
Modernization inquiries & risk containment.
We speak directly, without marketing euphemisms. Here is how our senior engineering pod handles the real constraints of production legacy software.
How do you handle zero-downtime migrations?
Can our internal team continue building new features while you modernize?
What if our legacy codebase has no documentation or automated tests?
What is the typical timeframe for a modernization engagement?
