Project details

You will get a production-ready REST API that your frontend team can rely on - tested, documented, and deployment-ready from day one.
I build APIs with Java and Spring Boot the way I built backend services at Santander Bank: clean architecture, proper error handling, and tests that actually catch bugs before your users do.
Every delivery includes PostgreSQL with managed migrations, Swagger documentation, Docker setup, and a clear README. I start with a design doc so we agree on the plan before I write a single line of code.
Stack: Java, Spring Boot, PostgreSQL, Docker, AWS, Kafka, Redis.

Small programming fix in Java or Groovy Volodymyr was able to quickly identify the problem and was able to solve the issue without much difficulty.
The code was decent and was able to solve my problem easily. I strongly recommend Volodymyr for any similar jobs.

About Volodymyr

Alicante, Spain - 7:59 am local time
Your AI-generated MVP got funded. Now it needs a backend that won't crash when real money flows through it. I've built payment systems at a top European bank - I'll make sure yours works.
I specialize in backend systems where failure means lost revenue: payment processing, API integrations, and microservice architectures for SaaS products and growing startups.

What I've shipped:
→ Santander Bank: Built instant payment features that cut transaction processing time by 12%, coordinating 8 cross-functional teams across 4 releases
→ IoT (Friendly Technologies): Decomposed a legacy monolith into 8 Spring Boot microservices - deployment time down 60%, test coverage up to 80%
→ Mobile Platform (Simbio): Architected a booking backend handling 500+ daily transactions with real-time WebSocket chat, reducing server response times by 35%
→ Workflow Automation: Integrated Flowable BPMN into enterprise systems, cutting 40% of manual process steps

How I work: I take your requirements, ask the right questions upfront, deliver clean code with tests, and communicate progress without you having to chase me. Available 10–30 hrs/week with EU timezone overlap.

Stack: Java 8–25 · Spring Boot · PostgreSQL · Docker · Kubernetes · AWS (ECS, RDS, S3) · Kafka · RabbitMQ · Stripe API · Supabase · GitHub Actions

Message me with a brief description of your project - I'll reply with a specific plan of how I'd approach it, not a generic pitch.

Steps for completing your project

After purchasing the project, send requirements so Volodymyr can start the project.

Delivery time starts when Volodymyr receives requirements from you.

Volodymyr works on your project following the steps below.

Revisions may occur after the delivery date.

API design and planning

I review your requirements, design the database schema and API endpoints, and send you a short design doc for approval before writing any code.

Core development

I build the API endpoints, database, and business logic. You get access to a staging environment or repo so you can see progress as I go.

Review the work, release payment, and leave feedback to Volodymyr.
