Kaustav Chanda — Software Engineer

I’m a backend-focused Senior Software Engineer with 5+ years of experience building cloud-native, distributed systems that power real-time, high-availability platforms in production. My core strength lies in designing scalable, fault-tolerant backend systems using C# / .NET (ASP.NET Core), with deep hands-on experience in WebSockets, asynchronous programming, concurrency, and low-latency communication. I’ve built and operated systems that handle parallel message flows, streaming data, message chunking and reassembly, and resilient reconnection strategies under strict SLA and uptime requirements. I have strong experience across AWS-based architectures, working with ECS/Fargate, Lambda, Kinesis Streams, and S3, and building event-driven, streaming pipelines with backpressure awareness and idempotent processing. I’ve designed services that support large-scale file transfers, including resumable uploads, pre-signed URLs, and memory-efficient streaming, optimized for both performance and cost. My work often involves plugin-based and adapter-driven architectures, enabling clean separation of concerns, extensibility, and safe evolution. I’ve enforced CI/CD pipelines with Dockerized builds, GitHub Actions, Jenkins, and compatibility checks, ensuring reliability across releases in complex systems. More recently, I’ve been working at the intersection of backend engineering and AI infrastructure—designing AI-adjacent backend systems such as RAG pipelines, vector-database-backed semantic search, document intelligence workflows, and real-time AI services. I focus on model-serving architectures, inference pipelines, and cloud-agnostic AI systems, with an emphasis on production readiness rather than experimentation. I care deeply about system design trade-offs, clean architecture, SOLID principles, observability, and resilience engineering—building systems that scale under real-world load without becoming brittle. My long-term goal is to grow into a Principal Engineer / Architect role, while staying hands-on with complex backend and distributed systems. I actively enjoy discussions around: - Distributed systems & platform engineering - Cloud architecture & event-driven systems - Real-time streaming & messaging - AI infrastructure & scalable backend design Always open to connecting on challenging backend problems, cloud-native systems, and AI-powered platforms.
