I'm a senior PHP developer with 25 years of experience, working with companies that need a reliable hand on the codebase that runs their business. My work is split between two kinds of projects: building new applications from scratch, and taking over existing ones. On the new-build side, that's usually custom SaaS applications, E-Commerce Systems and business tools, including auth, billing, dashboards, admin panels, and integrations. On the takeover side, it's stepping into existing codebases, stabilizing them, and building the features that have been stuck in the backlog. I work in Laravel, CodeIgniter, other PHP Frameworks and custom PHP. A lot of senior developers won't touch non-framework code. I will, and a meaningful share of my long-running clients and projects are exactly that: businesses with critical applications written outside the major frameworks, that need a developer who'll keep them running and extend them rather than push for a rewrite. Most of my clients turn into long-term relationships. A lot of my contracts have run for years, which I think says more than anything I could put on this profile. My focus is backend: PHP, MySQL, integrations, and API work, plus Linux and server administration when a project needs it. I handle frontend work too (JavaScript, HTML, CSS) when full-stack services are needed. I work independently, communicate directly, and don't need much hand-holding to get going on a project. If that sounds like the kind of developer you need, send me a message and let's get to work.

If your app is broken, behind schedule, or stuck with bugs you can’t diagnose, I can help. I’m a senior full-stack developer with 30+ years of experience fixing, stabilizing, and finishing production systems—especially React, Node.js, APIs, and databases. I’m often brought in when: • A project is partially built but stuck • A previous developer disappeared • Bugs are blocking launch • APIs or integrations aren’t working My focus is fast diagnosis, clear communication, and shipping fixes—not rewrites. I’m a hands-on developer with 35 years of experience delivering production software across web, backend, and infrastructure systems. In recent work, I’ve been building and fixing applications using React, Node.js, MongoDB, and modern cloud environments. I also work with Web3 systems when needed, including Ethereum and Solana smart contracts, token integrations, and wallet-based workflows. With experience across many languages and platforms, I adapt quickly to the problem at hand and focus on getting things working reliably. Common fixes I handle: • API integrations that fail, timeout, or return incorrect data • Third-party API auth, webhooks, and data sync issues • React rendering, state, and performance issues • Node.js / Express backend errors and crashes • MongoDB schema, query, and data issues • Finishing half-built MVPs I’m available for short-term fixes or ongoing support.
