About this gig

Build a focused, maintainable REST API with Java and Spring Boot.


I am a backend and AI/ML engineer with experience in production APIs, distributed systems, data integrations and cloud infrastructure. I focus on clear contracts, validation and maintainable code.


BASIC: one REST endpoint, request validation, tests, source code and setup guide. No database.

STANDARD: CRUD for one entity, up to four endpoints, one SQL database, validation, tests and setup guide.

PREMIUM: Standard scope plus deployment to one agreed AWS environment. You pay AWS and other provider charges.


All packages include source code and three revisions within the original scope. An endpoint means one HTTP method and route. Complex authentication, third-party integrations, migration, frontends, CI/CD and ongoing maintenance need a separate quote.


I also offer backend code reviews and custom scopes for larger systems. Before ordering, send the endpoints, sample requests and responses, database needs and target environment so we can confirm the right package.

I help startups turn AI ideas into reliable, working systems. As an AI/ML engineer at an analytics startup, I own AI solutions from discovery and design through deployment and production hardening. I build RAG chatbots, multi-agent workflows, data cleaning pipelines, and unified data-access layers. I also improve LLM reliability, tracing, monitoring, and inference costs. My stack includes Python, FastAPI, Java, Spring Boot, AWS, and Kubernetes. Tell me your goal and current setup so we can define a focused scope and clear deliverables.
