About Shaileshkumar Singh

I am a Staff Engineer with 12+ years of experience designing and delivering scalable, high-performance enterprise applications across full-stack environments. I specialize in building modular, data-intensive systems using Angular (Angular 17), Java, Spring Boot, and Node.js, with a strong focus on system design, performance engineering, and clean, maintainable architecture. At Synopsys, I work on high-impact product features and platform capabilities, driving improvements in scalability, reliability, and user experience. I have led initiatives that significantly enhanced system performance through JVM tuning, Redis-based caching, and database optimization, while also enabling efficient handling of large-scale datasets. My experience spans microservices, micro-frontend architecture, and end-to-end feature delivery in complex engineering environments. Beyond technical execution, I actively mentor engineers, drive code quality standards, and contribute to architectural decision-making. I enjoy solving complex problems, guiding teams toward scalable solutions, and improving engineering practices that enable faster, high-quality delivery. I’m also deeply interested in emerging technologies and have hands-on experience with AI/LLM systems, including Retrieval-Augmented Generation (RAG), MCP, and agent-based frameworks. I’ve applied these concepts to build intelligent automation workflows and chatbot integrations that enhance developer productivity and system capabilities. Core areas of expertise: • Full Stack Development (Angular, Java, Node.js, Spring Boot) • Scalable System Design & Microservices Architecture • Performance Optimization (JVM tuning, caching, query optimization) • Micro Frontends & Modular UI Architecture • AI/LLM Systems (RAG, Agentic Frameworks, MCP) I’m open to opportunities where I can contribute to building scalable, high-impact systems and drive technical excellence as a Staff/Lead Engineer.

Experience

1. Staff Engineer

   Synopsys Inc

   Jan 2024 — Present · Mumbai, IN

   1) Led and mentored a team of 4 developers, improving code quality, ownership, and engineering practices, resulting in reduced defect leakage and more consistent delivery outcomes.2) Drove architectural decisions and end-to-end feature delivery, aligning development priorities with business impact while enabling efficient task delegation and high-quality releases.3) Enhanced system reliability and user experience by reducing GC pause times to under 50ms (~30% improvement via ZGC tuning), improving API response times by 40–45%, and increasing throughput by 25% during peak load conditions.4) Improved frontend performance by reducing dashboard load times by 50% and enabling efficient rendering of 1M+ records through integration of AG Grid, Highcharts, and optimized UI strategies.5) Optimized backend performance by achieving 2–3x faster database queries through indexing and query tuning, while reducing memory usage by ~25% via efficient data structures and object reuse.6) Scaled backend systems using Spring Boot and asynchronous processing, reducing API response times by 30–45% and lowering database load by 25% in high-traffic environments.7) Implemented Redis-based caching and Cassandra integration to enable low-latency data access and high-volume data processing, improving system scalability and responsiveness.
