WORK HISTORY
Staff Architect @Applied Systems Canada
ON, CA
Engineered a blazing-fast AL3-to-IDM Mapping Engine with a recursive traversal & addressing algorithm; complex hierarchical transformations now complete in ~100ms for ~30 transactions, down from ~2 seconds each — a >95% latency reduction2. Optimized search performance in Market Appetite to Ask Kodiak integration by transitioning from eager to lazy loading and building a multi-layered in-memory & Redis cache framework, reducing search latency from 25 seconds to ~1 second and significantly enhancing user experience3. Architected a Redis-based Advanced API Quotas system enforcing carrier-level rolling monthly rate limits with strong consistency, preventingresource overuse across resource-intensive export APIs per individual carrier contracts4. Drove major performance wins across multiple services: optimized Looker SDK Run Query to non-blocking execution (>50% faster,>40% server responsiveness gain), introduced Celery for async task processing, and implemented multi-layered Redis caching, cutting race conditions and API response times significantly5. Strengthened system security & observability by resolving Snyk-flagged code injection vulnerabilities, fixing memory leaks in FastAPI, adding structured logging with user IP/agent tracing, integrating Datadog distributed tracing, and introducing unique request IDs for end-to-end API tracking6. Built a reusable Datadog tracing framework for GoLang that reduces tracing integration to one-liner statements, eliminating boilerplate acrossall GoLang projects, and developed an internal Debug API that visualizes non-human-readable AL3 file hierarchies to accelerate developer debugging7. Resolved complex UX challenges by implementing Cookieless Looker embed dashboards to fix multi-tab session conflicts, designed the Bookroll API for unified XML/AL3/IDM file generation, and authored comprehensive Confluence documentation enabling seamless team-wide adoption

ABOUT JUNAID A.
Staff Software Architect with 11+ years of software development experience, architecting and delivering highly scalable, high-performance distributed systems across insurance, SaaS, and enterprise domains2. Achieved >95% latency reduction in AL3-to-IDM transformations by designing a recursive traversal & addressing algorithm, processing ~30 complex transactions in ~100ms vs ~2 seconds each3. Reduced search latency from 25 seconds to ~1 second in Market Appetite integration via lazy loading & multi-layered in-memory/Redis caching, driving significant performance gains and user experience improvements4. Led various teams of 2-3 senior software engineers & engineered highly scalable, serverless, cost-effective & highly performant systems in AWS5. Improved performance of a highly used client facing REST API by over ~93% by rebuilding from scratch & slashed infrastructure costs by ~66.7%6. Optimized sync algorithm time complexity from O(n^2) to O(n), which increased performance by ~90%7. Played DevOps role and engineered automated project code build & deployments using AWS IaC solutions & achieved deployment time of less than 5-7 mins on average for approximately 30 serverless AWS components
