Java Monolith → Microservices — Step-by-Step, Docker, API Gateway | From $499
Your Spring Boot monolith is becoming a deployment bottleneck. We help you extract a single bounded context — auth, billing, notifications, user management — into a standalone microservice with its own database and API contract, connected via REST or message queue.
Extract monolith modules into independent Docker-containerized microservices. API gateway, service discovery, step-by-step migration. Not big-bang — controlled and reversible.
"Senior engineers who actually deliver what they promise. Rare."

Frequently Asked Questions
Yes. Before any work begins, we sign a Service Agreement covering: scope of work and deliverables, timeline and milestones, NDA (confidentiality), intellectual property rights, warranty terms, and payment schedule. We work with both companies (B2B) and individual clients. The agreement protects both parties and ensures clear expectations — included in every service at no extra cost.
We look for modules with clear boundaries, high change frequency, and independent scaling needs. Auth, notifications, and billing are common first extractions.
Yes. We use the Strangler Fig pattern — the monolith continues to function while the new microservice gradually takes over responsibility.
Message broker setup (Kafka or RabbitMQ) for async communication between the monolith and the extracted service is included. Both producer and consumer are configured and tested.
Shared databases are an antipattern for microservices. We design the schema separation strategy — either schema-per-service or database-per-service — based on your team's capacity and risk tolerance.
We use the Strangler Fig pattern — the monolith proxies requests to the new service while both run in parallel. Feature flags allow gradual cutover. Rollback is possible at any point.
This service includes a 14-day warranty. If anything doesn't work as specified after delivery — we fix it at no extra cost. No questions asked.
