Sr. Software Engineer | Java Backend Developer | Spring Boot | Microservices | AWS | GCP |Scalable Cloud Solutions.

About

I design and build backend platforms where Java microservices, cloud infrastructure, workflow orchestration, and AI tooling come together. With 8+ years of software engineering experience, my primary expertise is Java, Spring Boot, microservices, REST APIs, distributed systems, cloud-native architecture, and event-driven workflows. At Candescent, I designed and implemented customer agreements and consents, document management, onboarding, and task-management services from scratch using Java 25 and Spring Boot 4. These services support digital and assisted fintech onboarding journeys and integrate through Sales Orchestrator and Ops Orchestrator. My architecture experience includes BFF and API Composition, hexagonal architecture where adopted, Domain-Driven Design concepts, OpenFeign adapters, Temporal workflows, journey DSL, event-driven architecture, outbox pattern, multi-tenancy, standardized application chassis, traceability, observability, and zero-trust service communication. I work with GCP, GKE, Google Cloud Service Mesh, Kubernetes, Docker, Helm, Argo CD, GitHub Actions, sidecars, ingress routing, virtual services, authorization policies, PostgreSQL, Pub/Sub, and Cloud Storage. I also implemented MCP capabilities in document and consent services, enabling AI clients to invoke document upload, document linking, disclosure template, checklist, item, and resolution operations. My AI engineering interests include building Java-based LLM applications, Retrieval-Augmented Generation, vector databases, embeddings, semantic retrieval, prompt and context orchestration, Spring AI, Ollama, and local-model integration.
