Problem: Emerging direct-to-consumer and retail merchants in India require fast, seller-scoped storefronts with localized Indian Rupee (₹) pricing matrices, pincode check rails, and Cash on Delivery (COD) processing without expensive SaaS fees or slow monolithic themes.

What I built: Engineered the isolated multi-vendor storefront platform featuring a streamlined 4-step merchant onboarding wizard, dynamic theme token system (apparel, lifestyle, electronics, grocery), instant slide-out cart drawers, automated Indian pincode serviceability validation, Cash on Delivery workflows, and a merchant self-serve inventory and fulfillment control center.

Result: Delivered sub-second page rendering, zero-friction merchant store creation in under 5 minutes, and robust isolated routing for independent vendor storefront domains.

Problem: Enterprise financial reporting required consolidating disparate distributed banking transactional feeds into an auditable, real-time analytics module for operators.

What I built: Engineered the end-to-end enterprise reporting architecture utilizing Java, Spring Boot microservices, and modern Angular frontend components for dense financial data visualization and export pipelines.

Result: Delivered low-latency query rendering and streamlined regulatory report generation across institutional financial datasets.

Problem: Legacy monolithic delivery systems required decomposition into independent, resilient microservices without interrupting worldwide shipment advice dispatch.

What I built: Spearheaded full monolithic-to-microservice migration, created REST endpoints secured with OKTA Single Sign-On via PKCE flow, integrated P4e third-party logistics advice pipelines, and developed responsive Angular 15 operator interfaces.

Result: Decoupled core delivery services with zero authentication regressions and accelerated dispatch cycle times globally.

Problem: Small retail stores and hospital counters needed frictionless payment processing without heavy bank setup, alongside eliminating millions of physical paper slips.

What I built: Architected the plug-and-play InnovitiPOS EDC payment system with automated synZ OCR onboarding (PAN/GST), 2-way SSL (mutual TLS) fund settlement with YES Bank, and a smartphone-accessible E-Charge slip service dispatched via GupShup SMS.

Result: Delivered zero-bank-configuration terminal onboarding and seamless paperless digital transaction slips deployed across enterprise retailers and healthcare chains.

Problem: QA and integration engineering required executing massive test suites across varied distributed agent specifications without requiring programming syntax skills from testers.

What I built: Engineered AutomationNG to allow authoring large test suites using simple English-like statements with dynamic XPaths, and built ManageNG with Java, Spring, Hibernate, and Quartz Scheduler to schedule and distribute test execution with automated Jira bug logging.

Result: Drastically lowered scripting barriers for non-developer testers and enabled continuous scheduled regression verification across distributed test nodes.
