Work Experience
Senior Software Engineer
Tata Consultancy Services
- Built services for a SaaS platform for high-quality product delivery and talent engagement using AI-powered solutions, reducing job execution time by 62%, and maintaining consistent output quality.
- Worked closely with the design team to ensure consistent and high-quality UI in React, including complex UI components, like conversational AI workbench, artifact viewers, Monaco Code Editor, and a UI code previewer.
- Optimized Core Web Vitals, reducing LCP from 3.4s to 0.3s and initial bundle size by 80% (3.3MB to 670KB) via aggressive code-splitting, tree-shaking, and dependency management.
- Designed an enterprise notification engine using Azure Notification Hubs. Built an end-to-end system for real-time, multi-channel push delivery and event-trigger logic.
- Architected a full-stack observability framework using OpenTelemetry, Prometheus, and OpenSearch. Deployed real-time anomaly detection and alerting, significantly reducing MTTR across distributed services.
- Decoupled state management by migrating WebSocket connection pools to Redis. Enabled horizontal scaling and true statelessness by eliminating session stickiness across microservices.
- Migrated legacy services from synchronous thread-per-request models to asynchronous concurrent architectures, maximizing system throughput and resource efficiency.
- Developed a low-latency STT pipeline using WebSockets and Azure Speech Services. Implemented custom backpressure handling to ensure accuracy during high-throughput audio streaming.
- Implemented a centralized error telemetry system. Developed front-end error boundaries and reporting middleware to capture and prioritize actionable production diagnostic data.
Senior Software Engineer
NovaCrafts.AI
- Led the architecture and development of multiple SaaS and automation platforms for startups and internal initiatives, focusing on high-quality UI, scalable back-end systems, distributed workflows, and AI-powered tooling.
- Architected Remember Publisher, a GenAI platform that converts unstructured inputs such as journals and voice notes into structured, print-ready books using AI-driven content pipelines and automated workflows.
- Built ReferMat, a referral automation SaaS platform that manages the end-to-end referral lifecycle by generating AI-powered outreach sequences and automating follow-ups through a unified interface.
- Implemented multiple AI-driven automation workflows using n8n, enabling automated lead generation, article repurposing, and customer support flows, significantly reducing manual operational overhead.
Software Development Engineer 2
RapidStart Pty. Ltd.
- Spearheaded the design and implementation of a hierarchical multi-agent graph using LangGraph to respond to user queries dynamically using multi-agent task chaining and MCP servers.
- Built end-to-end UI components and back-end services for an AI phone agent platform in Next.js that automates inbound call handling and outbound communications processing 10,000+ calls monthly.
- Built an autonomous task execution agent capable of performing complex computer operations on behalf of users, leveraging vision models like OmniParser and LLMs using FastAPI and LangGraph.
- Developed a VNC-based pipeline for real-time visualization and interaction with autonomous agents.
Software Engineer
Tata Consultancy Services
- Worked on a product focused on developing digital experiences through high-level intent specification, reducing the development time by nearly 65%—from two weeks to two days.
- Developed end-to-end application features, including comprehensive APIs in Java (Spring Boot) and front-end solutions in React for no-code development.
- Utilized GPT-4 models for creating generative assistance for users, improving developer productivity by 60%, and built a VS Code extension to support, assist, and augment intent specification creation.
