You will get a Java developer for Java microservice development
Project details
You get a Java developer for microservice development - a Java developer who has
built distributed systems that survive real traffic. What you get: a Java developer who designs, builds and ships microservices on Java and Spring Boot - service decomposition, API contracts, messaging, deployment and observability. This Java developer works with Spring Cloud, Kafka, RabbitMQ, Docker and Kubernetes.
Microservices are not small monoliths: splitting badly costs more than keeping the monolith. This Java developer starts with boundaries - what belongs to which service, which data is the source of truth, where the transaction ends. A Java developer who skips this delivers a distributed monolith.
Legacy to microservices: if you already have a monolith, this Java developer modernizes it in steps that keep the business running. No big bang rewrite.
Delivered: services with REST and GraphQL contracts, event-driven communication with Kafka, data layer on PostgreSQL, MongoDB, Redis, Elasticsearch, tests with JUnit, Mockito and Testcontainers, plus logging, metrics and tracing.
10+ years as a Java developer and team lead.

About Anna
Java Developer | Backend Developer | Full Stack Developer | AI
Kyiv, Ukraine - 2:13 am local time
backend developer I own the full cycle: architecture, discovery, implementation, deployment, optimization and long-term evolution.
What clients hire me for:
- Payment gateway integration - Stripe, Google IAP, Apple IAP, custom payment providers
- Identity and SSO integration - Okta, Microsoft Entra ID, SAML 2.0, OIDC, OAuth2, JWT
- Legacy modernization - taking over an existing codebase instead of rebuilding it
- Backend bug fixing and performance work on production systems
- AI-assisted delivery - GitHub Copilot and Claude Code as a daily engineering practice, RAG and LLM API features on top of an existing Java backend
As a Java Spring Boot developer I work with Java 8-21, Spring Boot, Spring Cloud, Spring Security, Hibernate, JPA, REST API, GraphQL, Kafka, RabbitMQ, PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, Docker, Kubernetes, AWS and Azure. As a full stack software engineer I also cover Angular and React when a project needs one team instead of two.
Recent background as a backend developer and team lead:
- FinTech investment banking platform, Luxoft - team lead, secure APIs, entitlement
management, Kafka, Spark, MongoDB, Elasticsearch
- Marketing analytics platform, Newxel - data pipelines, real-time integrations, predictive analytics
- Telecom SDN/NFV platform, Netcracker - Java, Spring Boot, microservices at scale As an AI software engineer I hold Anthropic certifications - Claude Code 101 and AI Fluency Framework & Foundations - and I ship AI features in production Java systems, not in demos. This is what a modern Java developer looks like in 2026.
Every Java developer can write code that works today. This Java developer writes code that is still maintainable in three years, explains the trade-offs in plain English, and flags risks before they become invoices. Saying "done" here means tested, deployed and documented. If you need a Java developer who takes ownership of the product and not just of the ticket, send me the details of your project and I will tell you what I would do first.
