Passionate about backend engineering, API architecture, and system integrations, with hands-on experience across AWS, GCP, and Azure. Adept at leveraging AI-powered tools (ChatGPT, GitHub Copilot, Gemini, Roo Code and Claude Sonnet) to accelerate coding, improve workflows, and ensure quality delivery. Recent Work Highlights: • Designed and implemented backend services and APIs for a Java-based React Native mobile app with ML-powered diagnostics. • Employed AI code assistants (like Roocode) to scaffold initial project structure, generate boilerplate, and reduce manual effort during CRUD endpoint creation. • Migrated multiple enterprise websites from Drupal 7/8/9/10 → Drupal 11. • Built a NodeJS-based ETL migration framework to move content from legacy CMS into Contentful. • Applied natural language querying to validate data model assumptions, spot inconsistencies in schema relationships, and simulate API payload flows. • Designed robust API payload structures aligning with finalized DB schema and Figma app flows. • Led backend scoping in cross-functional team meetings, capturing vague requirements and translating them into clear architecture flows and sequence diagrams. • Generated and maintained architecture diagrams, Confluence pages, and sequence flows using Mermaid with AI-assisted formatting. • Developed expertise in API architecture and led the integration of scalable applications and API solutions. • Conducted multiple training sessions, including one-on-one meetings, to train the client team on using the product after handover.
