Hi I am a Senior Java Tech Lead with 10+ years in backend systems, specializing in Java 17+, Spring Boot, microservices, Hexagonal Architecture, and DDD. The main technical risk in hybrid Hexagonal + DDD microservices is inconsistency between domain rules and infrastructure layers, which leads to brittle services. I solve this by defining strict ports/adapters, bounded contexts, and shared contracts, then scaffolding the project skeleton with clean module boundaries. I build high-concurrency systems using PostgreSQL tuning, Redis for caching, locking, and queues, and asynchronous processing. For real-time or marketplace-style workloads, I integrate Kafka or RabbitMQ and design idempotent, event-driven flows. I deliver a production-ready backbone with Docker, CI/CD pipelines, and cloud-ready patterns for AWS or OVH. My approach emphasizes ownership, technical leadership, and decision-making that aligns architecture with business goals. Thanks, Hercules

Hi, I can step in as your Senior Java/Spring Boot Tech Lead Architect to redefine and lead the target architecture (Hexagonal + DDD + microservices), make the key technical decisions, and deliver a clean project foundation that the team can scale on. My approach: Run a short architecture discovery (current code, domains, key use cases, non-functional requirements, throughput/latency targets). Define bounded contexts and service boundaries, contracts (REST/events), and a consistent hexagonal structure (domain/application/adapters). Establish cross-cutting standards: error model, validation, logging/tracing, versioning, security, and testing strategy. Build the skeleton: Java 17+ / Spring Boot baseline, Postgres migrations, Redis patterns (cache/locking/queues), and optional messaging (Kafka/RabbitMQ) with local Docker setup + CI pipeline. Focus on high concurrency from day one (idempotency, optimistic locking, transactional boundaries, outbox pattern where needed). I’m comfortable leading backend delivery and mentoring the team with clear docs and decision records. I’ve worked on large-scale systems with Postgres and Redis, and can support real-time/marketplace-style workloads if applicable. To start, I’d like: current repo access, a high-level domain overview, expected scale, and whether you’re leaning Kafka vs RabbitMQ, plus target cloud (AWS/OVH).

Hola, Me interesa incorporarme como Arquitecto / Tech Lead Java + Spring Boot para definir y dejar sentadas las bases del proyecto de forma sólida y eficiente. Cuento con más de 10 años trabajando en backend Java, liderando arquitecturas complejas en entornos de alta concurrencia, y he diseñado e implantado con éxito arquitecturas Hexagonales con DDD sobre microservicios en producción. Puedo asumir rápidamente la redefinición de la arquitectura, tomar las decisiones técnicas críticas y programar el esqueleto inicial del sistema (estructura de dominios, puertos/adaptadores, contratos, configuración base, estándares), sin convertirlo en un proceso largo o burocrático. Trabajo habitualmente con Java 17+, Spring Boot, PostgreSQL y Redis (cache, locking, colas), y tengo experiencia real en sistemas distribuidos, eventos y alto tráfico. Quedo atento para conversar y entender el contexto del proyecto. Saludos, Juan

❤️Plazo: 5 días | Costo: $500 | Disponibilidad total en tu zona horaria❤️ Hola Ya he resuelto este mismo problema y puedo entregar el esqueleto backend con la arquitectura de microservicios Hexagonal + DDD en 5 días. Basándome en mi experiencia, el verdadero reto es definir una arquitectura escalable y concurrente que equilibre los microservicios, el almacenamiento en caché y la persistencia. Esto es importante, ya que los errores fundamentales pueden bloquear el desarrollo futuro. En un proyecto anterior de marketplace de alta concurrencia, lo gestioné mediante: ✔ Esqueleto de microservicios Hexagonal + DDD: estructura limpia y extensible ✔ Integración con PostgreSQL y Redis: almacenamiento, almacenamiento en caché y bloqueo fiables ✔ Decisiones arquitectónicas y documentación claras: permite una rápida incorporación del equipo Para continuar, solo necesito los límites de servicio que prefieras, el esquema de la base de datos y cualquier requisito de integración principal. ¡Espero poder hablar con más detalle en el chat!
