Freelance Full Stack Engineer

We are seeking a Developer to design and deliver cloud‑native, event‑driven microservices using Java, Spring Boot, and Kafka. You will model robust relational data structures, implement EDA patterns (Event Sourcing/CQRS), and contribute to business process automation with BPMN/Camunda. You’ll champion architecture best practices, CI/CD automation, and high quality standards across the SDLC.

Key Responsibilities

• Design & Development Build secure, resilient microservices with Java, Spring, Spring Boot.
• Implement event‑driven integrations using Kafka (producers/consumers, schemas, retries, DLQs).
• Apply Event Sourcing and CQRS where appropriate.
• Design and optimize relational database schemas (transactions, indexing, performance).
• Architecture & Quality Apply architecture best practices and patterns (e.g., hexagonal/clean architecture, DDD concepts, idempotency, circuit breakers).
• Produce application designs and BPMN models; maintain clear technical documentation.
• Ensure quality through unit/integration/contract testing, code reviews, and performance tuning.
• Automation & Operations Build and maintain DevOps/CI/CD pipelines (build, test, deploy, release).
• Contribute to observability (structured logging, metrics, tracing) and operational reliability.
• Process Automation Analyze business processes and implement Camunda workflows (BPMN/DMN), integrating with services and events.
• Collaboration & Communication Partner with architects, product owners, and QA to deliver incremental value.
• Provide technical presentations, documentation, and knowledge transfer to stakeholders.

Required Skills & Experience

• Core Backend Strong hands‑on experience with Java, Spring, Spring Boot.
• Expertise with Kafka (event streaming, consumer groups, error handling, schema evolution).
• Solid understanding of microservices and cloud architecture (12‑factor principles, configuration management, resilience patterns).
• Practical experience with Event‑Driven Architecture, Event Sourcing, CQRS.
• Design & Modelling Strong application design skills.
• Good knowledge of modelling tools/standards (BPMN).
• Data Proficient with Relational DBMS (schema design, SQL, ACID transactions, performance optimization).
• Graph databases knowledge is a plus (e.g., Neo4j).
• Delivery & DevOps Good knowledge of DevOps pipelines/CI‑CD and automated testing.
• Integration Knowledge of interoperability technologies: REST/gRPC web services, message‑oriented middleware, service bus/ESB, event architecture.
• Soft Skills Rapid self‑starter with excellent interpersonal and communication skills.
• Delegation and decision‑making skills.
• Strong writing (redaction) skills and ability to give technical presentations.
• Ability to apply high quality standards and adapt to fast‑changing technologies.

Minimum Qualifications

• Bachelor’s/Master’s in Computer Science, Engineering, or equivalent practical experience.
• Minimum 10 years experience in front and backend development
• Very good expertise in Angular 14+ framework and Typescript.

Ways of Working

• Hybrid collaboration; proactive communication and documentation expected.
• CI/CD‑driven delivery; trunk‑based development or GitFlow (aligned with team standards).
• Code reviews, automated tests, and continuous improvement mindset.
