• Alongside my industry work, I contribute to engineering education with a strong focus on performance, systems, and fundamentals.
• Help design a full-stack MERN curriculum that emphasizes how systems behave under load, not just how to use frameworks.
• Mentor learners on backend internals, request lifecycles, networking basics, database behavior, and performance trade-offs.
• Focus on building intuition around latency, throughput, concurrency, and resource utilization, drawing directly from production experience.
• Guide learners to connect DSA concepts with real system behavior, enabling better debugging and architectural decisions.

• This phase was about building strong ownership across both backend and frontend systems, with a focus on reliability and maintainability.
• Built internal admin and monitoring platforms used by operations and product teams to track system state and business metrics.
• Developed frontend applications using React, Material UI, and ShadCN, focusing on predictable state management and component reusability.
• Designed REST APIs with careful attention to data modeling, pagination, indexing, and query performance.
• Containerized services using Docker and implemented CI/CD pipelines with GitHub Actions, reducing deployment errors and release friction.
• Led migration efforts to TypeScript, improving code correctness and reducing runtime failures in production.
• Integrated multiple external services and APIs, handling retries, idempotency, and failure scenarios.
• Actively involved in sprint planning, on-call debugging, and resolving production incidents with a root-cause-analysis mindset.

• Working on high-traffic backend systems where performance, correctness, and scalability are non-negotiable. My role involves owning critical backend flows end-to-end and making architectural decisions that directly impact latency, throughput, and system stability.
• Architect and maintain MLM reward and commission pipelines using Node.js, Redis, and event-driven patterns, enabling near real-time settlements under high concurrency.
• Designed low-latency caching strategies using Redis (write-through, TTL tuning, hot-key handling), significantly reducing database pressure and improving request throughput.
• Implemented Node.js clustering and async workload isolation, improving CPU utilization and reducing tail latency during traffic spikes.
• Built fraud detection layers for affiliate systems using velocity checks, anomaly patterns, and historical behavior analysis.
• Analyze production bottlenecks using logs, metrics, and traces, and optimize critical paths across API, database, and network layers.
• Work closely with leadership to evaluate trade-offs around scalability, cost, and reliability for long-term system evolution.
• Actively mentor engineers on performance debugging, architectural thinking, and writing production-grade code.
• Participate in technical interviews, focusing on system design, fundamentals, and problem-solving depth.
