ESLint/Prettier hooks and SonarQube vulnerability scanning.

• Developed an e-commerce platform with Angular/Node.js for a major retail company
serving 175K+ customers by July 2022, boosting order throughput 13% via real-time
inventory APIs and distributed transaction processing (Kafka event streaming).
• Integrated Keystone.js for flexible content management, designing custom models for
product listings, user accounts, and order processing, reducing backend code complexity by
27% and accelerating feature release cycles by 31%.
• Implemented GraphQL for API communication, reducing the number of server calls by 28%
and improving data fetching efficiency.
• Accelerated frontend performance from 5.2s to 2.3s through React.lazy dynamic imports,
WebP image optimization, and Service Worker caching strategies.
• Integrated PCI-DSS compliant payment stack with Stripe/PayPal SDKs, achieving 10%
higher transaction reliability via idempotent retry logic by Aug 2021 and 3D secure
enforcement.
• Optimized AWS costs 20% ($48K/yr saved) using Lambda auto-scaling, S3 IntelligentTiering (1.2PB data), and CloudFront cache policies (92% hit rate).
• Enhanced security with mutual TLS, RBAC (Okta integration), and CSP headers – 40%
fewer security incidents while maintaining 99.99% uptime SLA.

• Built Next.js/React LMS platform scaling to 37K+ active users (25% growth), achieving 15%
lower bounce rates through SSR implementation (SEO rank from 50th to 20th) and webpack
code splitting.
• Integrated hybrid GraphQL/REST API layer (Django + Apollo Server), slashing data
latency 20% while supporting 40% more concurrent users via query batching and Redis
caching by Oct 2018.
• Modernized auth flows with JWT rotation/refresh tokens, reducing login duration from 4s to
0.9s by Feb 2019 and achieving Zero Truust compliance through HMAC-signed sessions.
• Drove 20% higher user retention via collaborative UX redesign – implementing automic
design patterns and WebVitals monitoring (LCP < 1.2s across 95% of pages).

• Architected Node.js event-driven platform for 50+ institutions, processing 2M+
transactions/day with 18% faster risk model execution via Kafka-streamed market data
pipelines.
• Developed real-time dashboards (D3.js/WebGL) achieving 92.3% reporting accuracy
(+18.8% YoY) by Oct 2016 through schema-first data validation and Canvas GPU
optimizations.
• Optimized MongoDB aggregation layers & Redis cache TTL policies, slashing query
latency 40% (from 850ms to 510ms) via compound indexing and hash slot rebalancing.
• Institutionalized Jest/Mocha test automation with CI/CD guardrails, reducing critical bugs
20% through snapshot testing and contract-first API development.
