About
Good software starts with a conversation. I bring senior full-stack development and Laravel Tech Lead experience, from understanding requirements to architecture, mentoring, and delivery. My freelance work also taught me to use proofs of concept and MVPs to test ideas against business needs.
How I build
Laravel is my usual starting point, with Livewire and Filament for interactive admin tools. On the frontend, I choose React or Blade to suit the project. I care about code the next person can understand and maintain.
What gets me thinking
I like the details that make a project interesting: a booking widget that needs to get along with someone else’s CSS, a directory that helps people find the right place, or a healthcare service where reliability matters at every step.
What I focus on
Faster workflows, dependable releases, and code that is easier to change. I read the docs, test critical paths, and add error reporting early, so the team has useful answers when something goes wrong.

How I can help
A new product, an existing codebase, or a team that needs an extra pair of hands. I work on defined projects and longer-term collaborations.
Laravel for the long run
Booking flows, payments, and admin panels people spend their working day in. I build with Laravel, Livewire, and Filament, with clear structure and a straightforward handover.
Interfaces that play nicely
React interfaces and embeddable widgets that work smoothly inside someone else’s site. WebGL joins in when interaction or a little spectacle adds something useful.
A fresh start for existing code
I work through technical debt and performance bottlenecks while the team keeps shipping. Recent work includes migrating a critical Laravel payment flow to event-driven architecture and optimizing ORM usage for a SaaS platform serving up to 200,000 monthly users.

Work
A few things I’ve helped build, improve, and bring into everyday use.
SaaS · Confidential
A SaaS platform serving 100,000–200,000 monthly active users. I migrated the critical payment flow to event-driven architecture in Laravel, optimized ORM usage, and worked through legacy technical debt. I own features from requirements to deployment and contribute to the product roadmap.
04
What I work with
People first. Then the tools that help us build something useful together.
PHP · Laravel
Application logic, queues, and scheduled jobs. I modernize legacy systems and have migrated a critical payment flow to event-driven architecture in Laravel.
Livewire · Filament
Interactive admin panels, built within Laravel and easy to keep moving forward.
MySQL · Redis · Laravel Horizon
Database work, ORM performance optimization, and Laravel queues. I use Redis and Horizon alongside the application backend.
APIs · Integrations
Reserve with Google and Point-of-Sale integrations, API documentation with Swagger and Scribe, and request inspection with Postman.
React · TypeScript
Interactive frontends and embeddable widgets. My work includes a canvas floor planner with drag-and-drop reservation management.
WebGL · three.js
A little depth, motion, and room to play. This site is one example.
Frontend foundations
JavaScript, HTML, responsive web design, Tailwind CSS, Bootstrap, SCSS, and jQuery. I have also worked with kepler.gl and WordPress.
Tools · Workflow
Git, PhpStorm, XDebug, Figma, Jira, Confluence, and Scrum. Code review and mentoring are part of how I work with a team.
People · Technical leadership
I work directly with clients and developers to turn requirements into practical decisions. As Laravel Tech Lead at Super-Pharm, I mentored developers, taught Git, and helped external teams resolve technical blockers.
