About

I am a Full Stack Product Engineer who thrives at the intersection of robust backend data architecture and intuitive frontend experiences. Over the past two years, I’ve focused on building foundational SaaS modules, integrating secure payment infrastructure, and optimizing platforms to handle heavy data flows without breaking a sweat. What I Do Day-to-Day: System Architecture & Event Processing: I design robust, event-driven systems using Node.js and Python, leveraging tools like BullMQ and Redis to process complex batch operations and background data pipelines with low operational risk. Database & API Optimization: I map out scalable SQL/NoSQL database schemas and optimize query performance to significantly cut down API response latency for enterprise platforms. Intuitive Workflow Design: I translate complex business requirements and Figma designs into responsive, highly available TypeScript and React applications, making massive datasets easy for business counterparts to navigate. Selected Impact Highlights: Accelerated Feature Delivery: Co-developed a reusable UI component library during my time at LivSmart, cutting down engineering delivery timelines by 25% while maintaining strictly well-tested, clean code. High-Risk Transaction Integrity: Engineered full-stack workflows handling core transactions, webhook processing, and secure cash movements, explicitly preventing failed states and maintaining perfect database synchronization. End-to-End Ownership: Successfully took ownership of critical product modules (like the AI Protect platform at Snet Labs), earning a Certificate of Recognition for delivering fast, reliable production impact. Let’s Connect I'm always eager to collaborate with engineering teams, product managers, and founders who are solving complex data orchestration and fintech problems at scale. 📬 Reach out via LinkedIn message or email me directly at sainisourav279@gmail.com.

Work experience

Software Engineer at SNeT Labs Private Limited, Aug 2024 - Jun 2026 · 1 yr 11 mos, Noida, Spearheaded the end-to-end development of high-performance full-stack web applications, translating complex business logic and client designs into scalable, production-ready systems. Architected robust backend services and RESTful APIs using Python and Flask, implementing asynchronous workflows and queue-based data processing to handle heavy event and batch pipelines. Engineered highly optimized frontend architectures in TypeScript and React; eliminated unnecessary re-renders using useCallback, useMemo, and strategic state management to visualize massive datasets flawlessly. Streamlined containerization and infrastructure reliability by deploying multi-service applications via Docker and Docker Compose, ensuring seamless inter-service communication and low operational risk. Optimized network infrastructure and production grade availability by configuring Nginx as a reverse proxy with secure request routing, proxy pass rules, and automated service health checks. Managed production deployments on Linux (Ubuntu) environments running Gunicorn and Uvicorn servers, maximizing system uptime and reducing API response latency. Championed engineering excellence and code maintainability across the team by enforcing strict ESLint rules, writing comprehensive inline documentation, and driving rigorous code reviews.

Frontend Web Developer at LivSmart automation and security, Aug 2023 - Oct 2023 · 3 mos, Kurukshetra, Haryana, India, Developed an interactive, real-time web dashboard using React.js to seamlessly manage and orchestrate home automation IoT devices with zero noticeable latency. Accelerated data-fetching efficiency and frontend responsiveness by integrating RTK Query for advanced API state management, reducing redundant network requests. Partnered with senior engineers to architect a library of reusable UI components using Material UI, cutting feature delivery timelines while ensuring clean, predictable, and well-tested layouts. Collaborated closely with backend engineering teams to debug complex cross-stack bottlenecks, integrate end-to-end workflows, and guarantee high system availability.
