Led development of performance-critical Rust microservices processing >15K TPS with <90ms p95 latency. Built a real-time promotional engine using Redis pub/sub and PostgreSQL, with scalable modular design. Designed observability architecture using Grafana, Prometheus, and custom metrics collection to optimize throughput. Delivered presentations on service design and performance profiling to cross-functional teams. Deployed production services on AWS Lambda, using CloudWatch logs for debugging and monitoring. Achievements: Reduced average API latency by 40% via profiling and async tuning. Created CLI tools for performance metrics tracking and internal QA benchmarks.

Developed backend services to integrate with Solana smart contracts, using Rust and Anchor framework. Created on-chain/off-chain sync layer using JSON-RPC and WebSocket streams across Solana and EVM chains. Implemented DEX aggregator backend interfacing with Serum, Orca, and Raydium using high-performance caching and aggregation. Wrote Rust-based CLI utilities for node syncing and log indexing across validator and RPC nodes. Integrated services with AWS Lambda, used S3 for archival storage, and CloudWatch for event tracing. Achievements: Increased data ingestion throughput by 2x using async concurrency and Redis streaming. Delivered production-ready Solana service integrations for three DeFi partners under SLA.

Built Rust-based backend analytics pipelines with real-time response tracking and statistical aggregation. Developed Java service adapters and integrated them with new Rust services using PostgreSQL. Delivered internal CLI profiling tools written in Rust and C++ for low-level performance diagnostics. Presented engineering topics including OOP best practices, performance profiling, and service modularization. Achievements: Reduced system memory footprint by 30% through service decomposition and code-level optimization. Created unified monitoring dashboards using Prometheus and Grafana with custom alerting rules.

Developed backend APIs and frontend templates for SME clients using Laravel and Symfony. Refactored legacy PHP codebases to modern standards with SOLID principles. Created modular components using MVC, ensuring consistent logic separation and maintainability. Key Achievement: Improved uptime and performance across 10+ client websites by optimizing code delivery and DB performance.
