Senior Software Engineer - Frontend

Appinventiv · Aug 2024 – Present

• Architected the React frontend for an enterprise RAG-powered AI assistant serving 50K+ monthly users real-time flight support, AI-assisted conversation, and human-agent handoff reducing manual support tickets 35%.
• Rebuilt a commerce platform's ordering core after finding its five surfaces (product detail, cart edit, inline drawer, favorites, quick reorder) were the same editor with different seeds unifying them into one shared, framework-agnostic TypeScript engine and normalizing the catalog at the data-layer boundary to replace O(n) scans with O(1) lookups, leaving pricing and nutrition logic a single implementation reusable by the React Native client.
• Owned the client authentication boundary, moving sessions to httpOnly cookies and adding a mutex-guarded refresh-and-retry interceptor that collapses concurrent 401s into a single refresh eliminating client-side token exposure and reducing the XSS attack surface.
• Designed the Node.js BFF fronting the assistant orchestrating AI services, enterprise APIs, and authentication behind one contract so credentials never reached the browser and built the streaming voice layer on Groq, Azure Speech, and PlayHT that holds conversational response under 500ms.
• Architected a Next.js application on Server Components, Server Actions, and Route Handlers to keep enterprise AI workflows server-side, delivering a production Legal AI Assistant that reasons over enterprise documents via RAG while holding LCP under 2.5s and reducing TTFB.
• Led frontend architecture for 3–5 engineers through design and pull-request review, building a reusable platform of 30+ shared components, templates, and tooling adopted across multiple enterprise applications, and codifying standards as automated CI gates typed API boundaries, coverage floors, and accessibility checks.

• Engineered a high-frequency-trading IRMS on a micro-frontend architecture, isolating deployment boundaries per trading domain so teams shipped independently, and cut main-bundle size 45%.
• Built a query builder that compiles trader-defined predicates into backend queries over indexed warehouse data, returning results to a sortable, filterable table with React-ECharts visualizations letting quant traders explore datasets without engineering support.
• Eliminated cross-tab state drift by centralizing shared state in a Shared Worker and broadcasting updates over the BroadcastChannel API, keeping every trading tab consistent with no observable synchronization lag.
• Cut API response times 20% for critical trading data by profiling and indexing the Strategy microservice's query paths.

• Redesigned the multi-step checkout funnel to remove UI friction, increasing conversion 18% and reducing cart abandonment 5%.
• Integrated Stripe to bring the payment flow into PCI-DSS compliance, and cut failed payments 12% with automated retry logic and webhook-driven error handling.
• Architected a real-time outage notification framework syncing grid-status data to user accounts, improving restoration-estimate accuracy 40%.
• Raised application performance 20% by migrating legacy modules to hooks, code splitting, and dynamic imports.
