Pokédex App

React NativeExpoTypeScriptPokéAPI
Problem

Build a complete, production-quality mobile app — not a tutorial clone. The challenge was consuming a third-party API responsibly while delivering a polished, performant experience.

Key Decisions
  • Custom 24h TTL caching via AsyncStorage to respect PokéAPI's fair-use policy.
  • Race condition handling using useRef guards to prevent stale async callbacks.
  • Smart search fallback: filters loaded Pokémon first, falls back to direct API lookup if needed.
  • Type-aware dynamic theming: UI recolors based on the Pokémon's primary type at runtime.

ArcSmith

TypeScriptReact FlowRustREST API
Problem

Game writers and AI agents need a visual tool for branching narrative — a non-linear story graph editor that can be queried programmatically by external tools.

Key Decisions
  • Node-based canvas using React Flow for the visual editing layer.
  • Rust-based background REST API for performance-critical operations and asset library management.
  • Architecture separates the visual layer from the data layer — the REST API is fully independent of the frontend.

antigravity-unity

C#UnityEditor Tooling
Problem

Unity's built-in editor doesn't support modern AI-assisted coding environments. Developers working in Unity had no way to leverage the Google Antigravity IDE workflow.

Key Decisions
  • Built as a Unity Package Manager (UPM) compatible package for frictionless installation.
  • Bridges the Unity Editor event system with external IDE communication protocols.
  • 23 GitHub stars — adopted by other developers without any promotion.

Philosophy & Background

About

"In an era where AI can write code, I believe a great software engineer isn't defined by syntax, but by their ability to design, architect, and scale resilient systems."

I am a Full-Stack Engineer based in Pakistan with a recent BS in Computer Science from the University of Management and Technology. I spent the early years of my career deeply immersed in the game development industry, leading teams and engineering complex, real-time multiplayer systems and VR experiences.

Recently, I pivoted into full-stack and mobile development to tackle new engineering challenges. At Termnl Tech, I am combining my rigorous background in systems architecture with modern web technologies to build scalable RAG pipelines, intelligent backends, and performant cross-platform applications. I bring the performance-obsessed mindset of a game developer to every web and mobile product I build.
