About

I build the features that actually ship — full-stack, end-to-end, no handoffs. In 5 years at Enablix (a B2B SaaS company), I've owned everything from Java microservices to Angular UIs to a production RAG chatbot now used by the sales team daily. What I've delivered: → Built a RAG-based chatbot using OpenAI GPT + OpenSearch + LlamaIndex that cut sales asset retrieval time and reduced manual search effort across the team → Developed an LLM-powered auto-tagging and excerpt system for sales content, improving asset discoverability and eliminating hours of manual categorization per week → Integrated two analytics platforms by engineering data normalization layers across mismatched data models — early testing showed a 40% reduction in user context-switching Stack I work in daily: Java · Spring Boot · Angular · TypeScript · Ionic · MongoDB · REST APIs · OpenSearch · LlamaIndex · OpenAI API · Git Currently open to Senior Full Stack or Full Stack Engineer roles — ideally at a product company where AI integration is part of the roadmap.

Work experience

Full Stack Developer at Enablix, Mar 2021 - Present · 5 yrs 9 mos, Ashburn, VA, Full-stack engineer on two products: Enablix (B2B sales enablement SaaS) and Clake (AI-powered sales chat), working across Java backend, Angular/TypeScript frontend, Node.js, and Ionic mobile — owning features end-to-end from design to production. Clake AI Platform (built 0→1): Engineered the core of Clake from its earliest PRs — including backend-persisted HTML artifacts with versioning (521 lines, 15 files, dual-engine: OpenAI + Claude), full activity audit tracking (LOGIN, APP_ACCESS, CHAT_SESSION events with paginated endpoints and permission guards), conversation deep-linking with activity capture, and a citation summary system. Built across both TypeScript frontend and Node/Prisma backend. Enablix x Clake Analytics Integration: Merged two distinct analytics platforms into a single unified dashboard — required designing a typed data translation layer (ClakeActivityClient + ClakeInsightsService) between mismatched event-driven and metric-based data models across 4,617 lines of changes. Resulted in a 40% reduction in user context-switching in early testing. Security & Access Control: Designed and shipped hub-level member-only access control (OPEN/MEMBERS_ONLY model with OTP sign-in, request-access flows, and per-link overrides) across 541 lines and 23 files — proactively requested dual architect review given the security surface area. Platform breadth (5 years, 1,200+ merged PRs): Mobile app (Android + iOS, Ionic) · Chrome Extension (InboxSDK, Gmail link resolution) · Salesforce contact sync · CRM deal linking with retroactive backfill · HubSpot integration · Microsoft Graph API (meeting transcripts) · RAG chatbot (OpenAI GPT + OpenSearch + LlamaIndex) · LLM auto-tagging pipeline · Markdown native preview · SCORM tracking · Reporting & analytics dashboards

System Engineer at Tata Consultancy Services, Jul 2019 - Mar 2021 · 1 yr 9 mos, Bengaluru, Worked on networking device QA for British Telecommunications (BT), building automation scripts and test frameworks to qualify new hardware at scale. Automated testing workflows for new networking devices, reducing manual effort and accelerating BT's device qualification cycles. Authored test plans and coverage schedules across device categories, maintaining quality benchmarks and enabling consistent cross-team handoffs. Caught defects early through systematic bug reporting in close collaboration with development teams, reducing rework cycles in the hardware validation pipeline.
