Satender K.

Hi, I have 15+ years of experience designing and developing web applications, mobile applications, application integrations, and automation systems - across enterprise, startup, and independent-project settings. Here's a summary of my core expertise: Java: REST APIs, SOAP web services, microservices, Spring Boot. Golang: gRPC, Protobuf, Gin, microservices. Cloud (AWS): EC2, CloudFront, Route 53, S3, Load Balancer, and general cloud architecture/deployment. Integration: Oracle SOA Suite, Oracle Service Bus (OSB), XSLT, XQuery, WSDL. Build tools: Git, Gradle, Maven. Databases: SQL (MySQL, Oracle, PL/SQL) and NoSQL. Messaging/Queues: Apache Kafka, RabbitMQ, ActiveMQ. Project management: Jira, Confluence, Kanban Flow. Testing: Postman, SoapUI. Security: OAuth2, OpenID Connect, Keycloak. Application servers: WebLogic, Apache Tomcat. RPA: UiPath. AI-driven development: Extremely proficient with AI coding tools like Claude and Codex - I use them to fast-track development and bring down the cost/time of building applications, not just for autocomplete-style assistance. Beyond the tooling, I have strong grounding in application architecture and design patterns - both synchronous and asynchronous - and I use that to make deliberate design tradeoffs rather than defaulting to one pattern everywhere. Recently, I independently designed and built 7+ applications end to end - using AI-assisted development to move faster and cut build costs - including their cloud architecture, and deployed all of them on AWS. Security is built into that process, not bolted on afterward - I follow secure-by-design practices throughout development and deployment. I'm equally comfortable as an individual contributor and as a lead - I've managed and grown large development teams, and I can plug in wherever the project needs me: hands-on development, architecture, or team leadership. Happy to discuss your project in more detail. Regards, Satender Kumar
