About Me
Full-Stack Software Engineer
I build scalable products across backend and frontend, with a focus on clean architecture and fast execution. Comfortable picking up new languages and frameworks by relying on strong core engineering principles.
My philosophy is that while tools and syntax change, the underlying concepts system design, data flow, and problem-solving remain consistent. I focus on mastering those fundamentals and applying them across different stacks.

My Framework
Valhalla is my PHP framework for clean APIs, service communication, and fast CLI-first development.
Valhalla
A focused framework for developers who want fast JSON APIs, clean architecture, service-to-service communication, and a CLI that helps you move quickly without carrying the overhead of a monolith.
I built Valhalla because I wanted backend development to feel lighter, clearer, and more free. My philosophy is simple: give developers strong structure where it matters, then stay out of the way so they can shape services the way they actually want to build them.
$ composer global require asyassin10/valhalla-framework
$ valhalla new project my-service
$ cd my-service
$ composer installMicroservices-First
Built for JSON APIs, internal service endpoints, and backend systems without unnecessary framework weight.
CLI Productivity
Scaffold projects, controllers, middleware, services, routes, auth flows, and local agents from the terminal.
Practical Architecture
Routing, middleware, JWT auth, service-to-service calls, and agent-style workers in one focused PHP toolkit.
Composer Packages
Open-source PHP packages available on Packagist

PHP Has No Good Microservice Framework. So I Built Valhalla.
Laravel is too heavy, Slim is too bare, and Lumen is deprecated. I got frustrated and built Valhalla — a microservices-first PHP framework with CLI scaffolding, JWT auth, a service client, and local agent workers. ~300KB, two runtime dependencies.
Read on MediumBuilding a PHP Extension in C (And Locking It Behind a License)
When PHP isn't fast enough, you go lower. This article covers writing a real PHP extension in C from scratch — handling parameters, zvals, and memory — then adding runtime license validation so your compiled .so only runs on authorized servers.
Why Cosine Similarity Is the Engine Behind Every RAG System
Cosine similarity doesn't measure distance — it measures direction. This piece breaks down how the formula works, why embeddings encode meaning in vector direction rather than magnitude, and why tools like Qdrant and Pinecone rely on it for semantic search.
