Legacy system stuck? We migrate monoliths to microservices, old databases to modern cloud, and messy codebases to clean architecture — with zero downtime.
The big-bang rewrite is almost always the wrong answer. We use the strangler-fig pattern: build the new system alongside the old one, migrate traffic gradually, and decommission legacy components as replacements go live. This keeps your product running throughout the migration — no multi-month freeze.
We have migrated Django monoliths to FastAPI microservices, PostgreSQL databases from on-premise servers to Neon on GCP, and mobile apps from legacy REST APIs to modern GraphQL schemas — all without downtime and without a single data loss incident.
Every modernization engagement starts with an architecture audit: a written document that maps every system boundary, identifies every bottleneck, and prioritizes the modernization work by business impact.

How much does architecture modernization cost?+
Engagements start from $15K. Every one begins with a written architecture audit, so the modernization roadmap — and its cost — is scoped before any migration work starts.
What's the process?+
Four stages: Audit (current codebase and infrastructure assessment, written findings report), Roadmap (prioritized modernization plan with effort estimates and risk ratings), Migrate (strangler-fig pattern — modernize in place, no big-bang rewrite), and Handoff (architecture docs, runbooks, and team training).
Do we have to freeze feature work during the migration?+
No — we use the strangler-fig pattern: the new system is built alongside the old one, traffic migrates gradually, and legacy components are decommissioned as replacements go live. Your product keeps running throughout.
What kind of migrations have you done?+
Django monoliths to FastAPI microservices, PostgreSQL databases from on-premise servers to Neon on GCP, and mobile apps from legacy REST APIs to modern GraphQL schemas — all without downtime and without a single data-loss incident.
