AI Document Processing Platform: Built from scratch a high-throughput document processing system using Temporal workflows andGPT-4/LLMs. EnabledAI-powered Capital Gains parsing for any broker format. Achieved 80-100 docs/min throughput, P99 latency 2-3s, event loop lag <5ms. Load tested up to 100 RPS using Locust.
Tax Calculation Engine: Designed scalable microservices for end-to-end ITR automation handling millions of tax calculations. Built RESTful APIs for tax data submission to ITD and automated ITR filing for users.
AELMS (AI-Powered Exception Lifecycle System): Architected intelligent exception handling platform using LLM-based error classification and AI-generated fix suggestions. Built smart retry systemwith fingerprint-based deduplication. Impact: 60% reduction in support tickets, resolution time from 48-72 hrs to <4 hrs (12-18x faster), 100% user visibility (was 0%), auto-retry for all affected users on fix deployment.
Browser Automation Service: Built BrowserBase-powered automation for broker statement downloads (Zerodha, etc.), eliminating invalid report uploads. Integrated with document processor for automatic parsing.
GraphQL& .NET 9Upgrade: Led platform upgrade from .NET 6 to .NET 9, GraphQL 4.x to 8.6.0 across 867 files. Achieved 4x GraphQL response improvement (2-3s to 600-700ms), validation time reduced from 927ms to 40ms (23x faster), parallelized DB operations reducing latency by 60%.
Observability &Monitoring: Establishedmonitoring stack usingGrafana, CubeAPM, and Coralogix for distributed tracing and alerting across microservices.
AI Adoption & Leadership: Driving AI revolution across the team - mentoring junior developers on AI tools (Claude, GPT-4, Copilot), prompt engineering, and integrating LLMs into development workflows.
