I am Nrishinghananda Roy, a backend and systems engineer driven by the challenge of designing Highly Reliable Infrastructure and Distributed Systems.
With a core focus on Rust, Kubernetes, and AWS, I strive to build architectures that are memory-safe, performant, and scale gracefully. I am passionate about engineering robust solutions that quietly and predictably empower the products they support.
I don't just write code; I engineer resilient systems. Here is the tangible impact of my recent work.
Re-architected legacy Java microservices into Rust (Axum), slashing latency from 3s to <200ms. Optimized critical paths to handle high throughput without scaling costs.
Managed 60+ distributed EC2 instances with Terraform. Architected robust data pipelines for legal platforms and automated deployment processes in CI/CD pipelines.
Automated complex legal workflows by rewriting Python pipelines in Rust. Reduced manual effort by 60% and accelerated document generation by 7x.
Deeply invested in building memory-safe, concurrent, and high-performance backends leveraging Rust. I appreciate its safety guarantees, allowing me to focus on creating robust, long-lasting systems.
Experienced in orchestrating containerized workloads. I use Kubernetes to build self-healing, scalable architectures that bring operational peace of mind, even across globally distributed setups.
Comfortable navigating the AWS ecosystem. I carefully design networks, manage compute resources, and deploy cloud-native solutions that are cost-effective, secure, and highly available.
I design pipelines that handle demanding throughput gracefully. With tools like Apache Arrow and optimized PostgreSQL, I solve complex data bottlenecks while striving for operational simplicity.
I believe in predictable deployments. I rely heavily on tools like Terraform and robust CI/CD pipelines to ensure that infrastructure changes are reproducible, safe, and easily auditable.
While my core expertise lies in backend and cloud architecture, I understand how the entire system connects. I thoughtfully expose APIs and integrate them smoothly to create reliable end-to-end experiences.
Deep diving into Kubernetes Operators, AWS Network Architectures, and Systems Programming in Rust. I believe that a solid grasp of fundamental infrastructure paradigms is key to building systems that simply don't fall over.
