Completed eSign frontend refactoring by introducing code-splitting and dependency optimizations, reducing JavaScript bundle size by 60% and enabling users on low-bandwidth (2G) networks to complete eSign journeys. Proactively built and shipped an AI copilot POC that turns natural-language prompts into validated low-code API configurations — combining retrieval-augmented generation (RAG), a self-validation and repair loop, and schema drift detection — cutting API build time by 80% (4 hours → 1 hour). Spearheaded the rollout of a centralized LLM Gateway with fallback, failover, and real-time monitoring across 20+ services; automated failovers shield ∼0.4% of monthly LLM traffic from provider degradation, and anomaly-detection MTTR dropped from days to minutes (>99% faster).

(2024-06 - 2026-04)

• Built a self-serve eSign dashboard with Role-Based Access Control (RBAC), enabling management of 30+ templates by non-engineering teams and reducing client onboarding time from 5 to 2 days for 20+ enterprise clients.
• Implemented PII data encryption and client-level data isolation as part of ASP compliance requirements, supporting production onboarding of multiple fintech and NBFC clients onto the eSign platform.
• Led a quarter-long conversion initiative for a top wealth-management client: built funnel analytics from vendor-pushed logs to pinpoint drop-offs, drove vendor-side UI fixes, and shipped Metabase/Hotjar-informed UX improvements — lifting journey conversion from 93% to 96% (∼40% fewer drop-offs).
• Integrated biometric signing mode into multi-signer flows and drove eStamping to production readiness through active vendor coordination; implemented ESP fallbacks with health-based vendor routing, maintaining 99.95% platform uptime through vendor downtimes.
• Drove API optimizations across the PDF generation module (text-size algorithm, input parser), sign URL creation, and callback handling, reducing P90 latency by more than 50% end-to-end.
• Reduced Time-to-Detection (TTD) in the alerting system by 99% (30 min → 1 min) by optimizing monitoring workflows.

• Automated the development of proof-of-concept (POC) results by creating an API request simulator tool, resulting in expedited responses to new clients and increasing customer conversion rates by 20%.
• Executed a zero-downtime embedding-model migration for a face-match service handling 1M+ calls/day — ran dual-writes to parallel Milvus vector collections, backfilled existing enrollments, and phased the client cutover — improving match accuracy with zero production degradation.
