Syed Shalish Raza

Designed and owned horizontally scalable backend services using Node.js, Express.js, PostgreSQL, and Redis, supporting 150K+ MAU, 2M+ API requests/month, and 3–5K concurrent users. Architected a multi-tenant Learning Management Platform from scratch, supporting 20+ organizations and 10K+ users, with strong data isolation, RBAC, and tenant-safe schema design. Designed and evolved 25+ relational database schemas, applying normalization, indexing, and backward-compatible migrations, improving P95 query latency by 35–40%.

Software Engineer at Careervira (2022-09 – Present)

• Designed and owned horizontally scalable backend services using Node.js, Express.js, PostgreSQL, and Redis, supporting 150K+ MAU, 2M+ API requests/month, and 3–5K concurrent users.
• Architected a multi-tenant Learning Management Platform from scratch, supporting 20+ organizations and 10K+ users, with strong data isolation, RBAC, and tenant-safe schema design.
• Designed and evolved 25+ relational database schemas, applying normalization, indexing, and backward-compatible migrations, improving P95 query latency by 35–40%.
• Optimized PostgreSQL performance using composite indexes, query plan analysis, efficient pagination, and connection pooling, increasing API throughput by ~45%.
• Implemented Redis caching strategies (cache-aside and write-through), addressing cache invalidation and TTL tuning, reducing read latency from ~180ms to <70ms and database load by ~50%.
• Built idempotent, fault-tolerant background processing systems, running 30+ scheduled workflows and processing 500K+ tasks/day with retries and failure recovery.
• Developed real-time analytics pipelines in Go (Golang) aggregating 70K–100K events/day, enabling near-real-time dashboards with sub-second aggregation latency.
• Integrated 6+ Spring Boot microservices via versioned REST APIs, implementing timeouts, retries, circuit breakers, and graceful degradation to handle partial failures.
• Improved end-to-end system performance and reliability, reducing P95 API latency by 35%, P99 latency by 25%, production incidents by 30%, and MTTR by 25% through observability and optimization.
• Collaborated cross-functionally with product, frontend, and infrastructure teams to evaluate system design trade-offs, ensure backward compatibility, and deliver zero-downtime deployments across environments.

FULL STACK INTERN at FULL CREATIVE (2022-06 – 2022-07)

• Built server-rendered web pages using Java Server Pages (JSP), improving UI consistency, maintainability, and separation of presentation logic.
• Implemented authentication workflows (Login/Sign-up) using core Java concepts (OOP, validation, exception handling, session management) to ensure secure and reliable user access.
• Collaborated closely with senior engineers and tech leads to understand application architecture, data flow, and coding standards, gaining hands-on exposure to core and advanced Java development practices.
