More reliable APIs
Clear contracts, validation, controlled errors and tests reduce surprises when frontend work, integrations or clients depend on the backend.

Freelance service
Optimization and maintenance
Performance, security, bug fixing, deployment and stability improvements.
- Free initial assessment An initial conversation to clarify the most useful next step.
- Direct communication You speak with the person analysing and building the work.
- Clear ownership Code, accounts, access and handover are defined.
Problem and outcome
What changes with Optimization and maintenance
The scope is built around a real problem and a verifiable outcome, not a generic list of tasks.
Problems it solves
The backend supports the business, but each change costs too much, integrations are fragile or the architecture no longer fits the product.Spring Boot backend development fits when you need reliable APIs, services or integrations on top of a maintainable Java base.
It can be a new API, an architecture improvement, an integration with external systems, a gradual migration from legacy or a focused intervention so the backend stops slowing changes down.
Better maintainability
A structure with separated responsibilities, useful tests and explicit decisions makes change easier without touching half the system.
Evolution in phases
For legacy or live systems, I prefer focused interventions that reduce risk before large rewrites become hard to justify.
Guide price
What determines the price of Optimization and maintenance
Three ways to start depending on the size of the need. Prices are indicative and final scope is agreed after the initial assessment.
One-off intervention
A quick review to locate an incident or risk and leave a clear next step.

What a Optimization and maintenance project includes
Final pricing depends on scope, integrations and project state. If it does not fit, I will say so before estimating.
Work included according to scope
- REST APIs with clear contracts, validation, security and error handling.
- Spring Boot services with maintainable structure, tests and separated responsibilities.
- Integrations with databases, queues, third-party services and internal processes.
- Observability improvements, health checks, Liquibase migrations and operational notes.
Boundaries we put in writing
- This is not a full audit and cannot guarantee a fix for third-party failures.
- This does not include rewrites, new functional areas or out-of-hours response.
- This does not include 24/7 availability or immediate response unless agreed separately.
Process
How I deliver Optimization and maintenance
My strongest technical base is backend work, APIs, Java, Spring Boot and systems that need to keep running in production.
-
Understand the domain, data, existing contracts and points where the system hurts.
-
Define a focused intervention: new API, targeted refactor, integration or phased migration.
-
Implement with tests, useful logs and explicit decisions around errors and retries.
-
Validate critical behavior and leave clear notes for operating or evolving the system.

Questions before hiring Optimization and maintenance
Do you only work with Spring Boot?
Spring Boot is my main backend base, but I can connect it with frontend work, databases, queues, external APIs and deployment workflows when the project needs it.
Can you help with a legacy migration?
Yes. I prefer phased migrations: identify boundaries, extract valuable flows and reduce risk before rewriting more than needed.
