Project details

You get a Java developer for a fintech project - a Java developer who has already shipped payment and banking systems in production. What you get: a Java developer for your backend on Java 8-21, Spring Boot and Spring Security. This Java developer integrates payment gateways (Stripe, Google IAP, Apple IAP) and identity providers (Okta, Microsoft Entra ID, SAML 2.0, OIDC, OAuth2), so every transaction is processed exactly once.
Why a fintech Java developer is different: a general Java developer writes an endpoint. A fintech Java developer thinks about idempotency, reconciliation, retries and audit trail before writing it. I spent three years as a Java developer and team lead on a secure investment banking platform at Luxoft, so this Java developer has seen what a failed payment costs. How we work: you describe the problem, this Java developer returns scope,
assumptions, risks and an estimate in hours, then delivers with demo builds and async updates. You get code, tests and documentation.
10+ years as a Java developer, Anthropic certified in Claude Code and AI Fluency - this Java developer ships with AI-assisted engineering, not slides.

About Anna

Anna T.Status: Offline
Java Developer | Backend Developer | Full Stack Developer | AI
Kyiv, Ukraine - 2:34 am local time
🧠 For the past 10+ years, I've been helping companies design, build, and scale enterprise software as a Java developer/Tech Lead. As a Java developer and Java Spring Boot developer I design and ship microservices that handle money, identity and third-party data without losing a transaction. As a
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.
