Support, Infrastructure & Tools

• Tech Stack: Next.js · Redis · PostgreSQL · Prisma · Distributed Systems
• Challenge: Concurrent transaction collisions, double-booking, and database node crashes under extreme traffic loads (>10k req/sec).
• Strategy: Re-engineered checkout flow using Redis distributed locks (Redlock pattern) to serialize writes on hot resources, backed by an async processing queue and pessimistic database row-locking.
• Metrics & Impact: 100% elimination of double-bookings, 40% improvement in TTFB, and successfully scaled to handle 15k+ writes/second without drops.

• Tech Stack: React · Node.js · MongoDB · Zustand · HTML5 Web Workers · IndexedDB
• Challenge: Heavy multi-warehouse inventory recalculation loops running directly on the browser's single main thread caused UI freezes and high frame drops.
• Strategy: Migrated state to a modular Zustand layer with strict selectors, offloaded background computations to dedicated HTML5 Web Workers, and implemented IndexedDB offline-fallback caching.
• Metrics & Impact: Reduced CPU execution blocking by 60%, maintaining 60fps rendering during calculations, and boosted operational efficiency by 35%.

• Tech Stack: Next.js · Shopify API · Web Performance · Tailwind CSS · Vercel Edge
• Challenge: Mobile search presence and retention dropped due to a 4.5s LCP on asset-heavy pages and high CLS on dynamic image blocks.
• Strategy: Transitioned storefront to a headless Next.js architecture on the Vercel edge, integrating optimized responsive Next.js image pipelines, local bounding box aspect constraints, and 60-second Incremental Static Rendering (ISR).
• Metrics & Impact: Cut mobile LCP from 4.5s to 1.1s, achieved a 100/100 Lighthouse performance score, and boosted sales conversion funnel by 22%.

• Tech Stack: React · Firebase · Cloud Functions · Consistency Modeling · LocalForage
• Challenge: Field engineers suffered constant work disruptions and database desynchronization due to intermittent remote network drops.
• Strategy: Developed an offline-first synchronization library that queues modifications locally, matching them against remote nodes via logical vector clocks and idempotent automatic merge triggers.
• Metrics & Impact: Maintained 99.99% database synchronization correctness across multiple nodes, preventing data loss for 50+ remote agents.

• Tech Stack: Next.js · Payload CMS · TypeScript · Event-Tracking · Stripe API
• Challenge: Webhook retries caused duplicate billing and product shipments, and the marketing team had zero visibility into funnel telemetry.
• Strategy: Implemented server-side event tracking bypassing adblock filters. Built an idempotent Stripe webhook receiver with Redis lookup locks to guarantee single transaction executions.
• Metrics & Impact: Reduced double-fulfillment errors to 0% and provided 100% telemetry funnel transparency.
