• Built a centralized release dashboard integrating GitHub APIs, deployment pipelines, and internal microservices to track releases across 5 production regions and staging environments, cutting manual tracking time from 15 to 2 minutes org-wide. • Diagnosed and resolved 150+ production incidents over 2 years through root-cause analysis, maintaining 99% SLA compliance and driving measurable improvements in platform stability for enterprise global customers. • Migrated 100+ flaky end-to-end test cases from Testim to a Playwright automation suite using the POM framework, eliminating third-party tool dependency and reducing regression validation time from 3 days to under 4 hours. • Built a channel-aware API layer in Java and Spring Boot that dynamically adjusted Freddy AI's system instructions based on the source platform (Instagram, WhatsApp, web), enforcing platform-specific response constraints to optimize AI output for each channel. • Developed 15 RESTful APIs using Java and Spring Boot to pipeline Freshchat conversation data into AI Agent microservices, enabling Freddy AI to process real-time customer interactions for enterprise global customers. • Leveraged AI-assisted development tools (GitHub Copilot, Cursor, Claude) to accelerate feature development, API design, and bug resolution across production applications and full-stack projects.

About

Full Stack Developer with 2+ years of experience at Freshworks, specializing in backend API development, AI Agent integration, and test automation. At Freshworks, I built production-grade systems including a channel-aware LLM pipeline for Freddy AI that dynamically tailored responses across Instagram, WhatsApp, and web channels for enterprise global customers. I also delivered an org-wide release dashboard that cut manual tracking time from 15 minutes to 2 minutes, migrated 100+ flaky test cases from Testim to Playwright reducing regression time from 3 days to 4 hours, and resolved 150+ production incidents while maintaining 99% SLA compliance. I work across the full stack — Java, Spring Boot, React.js, Node.js — with hands-on experience contributing to RAG-based AI products and multi-channel microservice architectures. I also actively use AI-assisted development tools like GitHub Copilot, Cursor, and Claude to ship faster in production. Currently open to Full Stack and Backend Engineer roles at product companies and startups. Feel free to reach out at thesasi.dev@gmail.com
