Java & Spring Boot
Translate business rules into backend applications, REST APIs, validation, and maintainable service code.
Capabilities & tools
Backend foundations.
Commerce depth.
Java and Spring Boot application development, microservices and enterprise integration, and Oracle ATG Commerce are the foundation of my work. React.js interfaces and AWS cloud services extend that work into connected applications.
Engineering capabilities
From application code
to connected workflows.
Microservices & Distributed Workflows
Contribute to service boundaries and modernization, connecting independently operated services with APIs and asynchronous processing.
Oracle ATG Commerce
Extend repositories, commerce pipelines, and the rules behind catalog, cart, pricing, promotions, checkout, and orders.
APIs, Messaging & Integrations
Connect customer, order, and operational workflows across platforms, with attention to mapping, validation, and failure investigation.
Payments & Checkout
Integrate card capture, payment choices, authorization, and order submission as connected stages of checkout.
Data, Performance & Reliability
Tune SQL, refine indexes, maintain audit records, and investigate application behavior through tests and production evidence.
React.js & Full-stack Applications
Build customer-facing interfaces connected to backend APIs. HelpCorner combines React.js with Spring Boot; MuniAI uses React and TypeScript for a local-first chat experience.
AWS Cloud & Engineering Delivery
Connect application development with cloud services. HelpCorner uses EC2, S3, IAM, and SQS alongside containerization; broader delivery work includes build pipelines and release validation.
