What I can lead

Senior engineering work where architecture, product judgment, and team standards meet.

The site is positioned for focused conversations around work where technical leadership has to create leverage, not only write code.

AI platforms

Designing observable AI workflow systems, evaluation paths, and production guardrails that teams can operate with confidence.

Architecture modernization

Moving legacy platforms toward typed services, clearer boundaries, and resilient delivery without pausing commercial momentum.

Engineering standards

Raising code quality, release hygiene, observability, and review practices so teams ship faster with fewer hidden costs.

Product delivery

Connecting technical choices to user value, roadmap trade-offs, and maintainable product execution.

Selected Work

Open-source tools with real adoption, plus product work with commercial intent.

The portfolio leads with projects that have earned usage and trust. Each card keeps the story practical: what it is, why it exists, and the engineering choices behind it.

Fetch PHP

45028

Modern PHP HTTP client inspired by JavaScript's fetch API. Async/await, streaming, SSE, middleware, RFC 7234 caching, and full PSR-7/18 compliance.

  • Fetch PHP is a modern HTTP client library for PHP that brings JavaScript's fetch API experience to PHP. Built on top of Guzzle, Fetch PHP allows you to write HTTP code with a clean, intuitive JavaScript-like syntax while still maintaining PHP's familiar patterns.
  • With support for both synchronous and asynchronous requests, a fluent chainable API, and powerful retry mechanics, Fetch PHP streamlines HTTP operations in your PHP applications.

Filterable

19610

Enhance Laravel queries with adaptable, customisable filters and intelligent caching to improve both performance and functionality.

  • Filterable is a Laravel package for turning HTTP request parameters into rich, composable Eloquent query filters. The base Filter class exposes a stateful pipeline that you can extend, toggle, and compose with traits to add validation, caching, logging, rate limiting, memory management, and more. Everything is opt-in, so you enable only the behaviour you need while keeping type-safe, testable filters.
  • Laravel 11.x, 12.x, or 13.x components ( illuminate/cache , illuminate/contracts , illuminate/database , illuminate/http , illuminate/support )

phpvm

16210

Simple PHP version manager for MacOS and Linux.

  • phpvm is a lightweight PHP Version Manager that allows you to easily install, switch between, and manage multiple PHP versions via the command line.
  • Seamlessly switch between installed PHP versions. Run commands with a specific PHP version without globally switching ( phpvm exec , phpvm run ). List available remote PHP versions from your system package manager ( phpvm ls-remote ). Install the latest available remote PHP version with phpvm install latest-remote . Update phpvm in place using phpvm self-update to pull the latest stable script version. Resolve ver…

Matrix

602

Bringing JavaScript-style async to PHP! Manage asynchronous tasks with ease using a modern, fiber-powered API for seamless concurrency and error handling.

  • Matrix is a PHP library that brings event-driven, asynchronous programming to PHP, inspired by JavaScript's async / await syntax. Built on top of ReactPHP's event loop, Matrix makes it easier to write non-blocking I/O operations and manage concurrency with a simple, intuitive API.
  • Important : PHP runs in a single-threaded environment. Matrix doesn't create true parallelism but enables event-driven, non-blocking I/O operations through ReactPHP's event loop. This means: ✅ Non-blocking I/O : Network requests, file operations, and timers don't block execution ✅ Concurrent operations : Multiple I/O operations can run simultaneously ❌ CPU-bound tasks : Heavy computations will still block the even…
