Subham Saha

Software Engineer with a deep specialization in designing, building, and optimizing robust, high-efficiency backend systems. My expertise lies in architecting pragmatic solutions using Java and Spring Boot, leveraging strong DSA and System Design principles to solve complex performance, data consistency, and resource-efficiency challenges. Core Strengths • Backend Architecture: Proficient in Java, Spring Boot, and Database/DBMS design. Expert in crafting highly efficient, concurrent, and thread-safe backend services with strict domain boundaries. • Modular Architecture & Scalability: Proven skill in System Design and modular event-driven patterns. Experienced in maximizing throughput by implementing asynchronous communication tools (Redis Streams, Pub/Sub) to decouple core business domains. • Full-Stack Foundation: Competent in React.js for frontend integration, complemented by a strong foundational understanding of Computer Networking, Operating Systems, and low-level Linux environments. • Platform & Reliability: Strong focus on full-stack Observability (Prometheus, Grafana), application resilience, containerization (Docker), and cloud infrastructure deployment (AWS). • Supporting Engineering: Practical working knowledge of JVM performance tuning, memory optimization, advanced SQL execution planning (PostgreSQL), and clean testing methodologies to ensure peak system efficiency. Key Responsibilities • Contributing to the design and development of low-latency, high-throughput monolithic APIs and modular architectures using Java and Spring Boot. • Architecting scalable database schemas, complex transaction logic, and optimized data access layers in PostgreSQL using advanced query techniques. • Implementing asynchronous event-driven patterns for fault tolerance, domain decoupling, and high-concurrency event processing. • Building resilient backend systems with integrated concurrency control, environment hardening, and comprehensive telemetry/observability. • Collaborating across frontend stacks like React.js and managing containerized cloud deployments via Docker to ensure absolute system reliability. My career is focused on building the foundational backend systems that power clean, reliable, and highly efficient applications without architectural bloat. I am always open to learning and discussing challenging opportunities in backend architecture, high-performance computing, and distributed data systems.
