About Me
I'm Rihad Jahan Opu, a passionate Full-Stack Web Developer dedicated to building scalable, modern web applications with Next.js 15, React 19, TypeScript, and cloud-native backend systems.
I specialize in crafting pixel-perfect, accessible user interfaces with dynamic motion design (Tailwind CSS, Framer Motion, GSAP) while architecting reliable backend services—including REST/GraphQL APIs, database modeling (PostgreSQL, MongoDB), secure authentication, and payment workflows with a relentless focus on 100/100 Lighthouse performance.
My engineering foundation is further sharpened by low-level systems programming in Pure Rust (creator of gladeshell, a sub-millisecond terminal with 0.0114 ms latency). This deep understanding of memory and runtime efficiency ensures every web application I ship is exceptionally fast, secure, and production-ready.

Selected works spanning ultra-low-latency pure Rust shell architecture, agentic AI workspaces, and full-stack platforms.
Pure Rust Open Source (MIT)gladeshell
MIT LicenseAn open-source (MIT Licensed), ultra-high-performance pure Rust shell environment and developer suite delivering a record 0.0114 ms (11.4 µs) prompt latency (~210x faster than Starship). Designed with zero external runtime dependencies and strict '#![deny(unsafe_code)]' memory safety, it integrates 55 hot-swappable prompt themes, pure Rust Git telemetry ('gix 0.88'), native Ratatui TUI utilities (Todo, Notes, Process Monitor), parallel Rayon multi-core compression, a 24-in-1 FFmpeg multimedia suite, and a hardened AES-256 PBKDF2 security vault.
