Senior WordPress & PHP Developer | Custom Plugins + AI Integration

I'm a senior WordPress and PHP engineer with 10+ years of experience building custom plugins, rescuing broken codebases, and running full server stacks. I also integrate AI (OpenAI, Claude, RAG) natively into WordPress. Deep code, no bloat, no surprises. Maybe you need a plugin built to exact specs because nothing off the shelf works. Or a legacy bug fixed that everyone else gave up on. Or AI features inside your WordPress site without paying monthly SaaS fees. That's the work I do. A bit about me: I'm Ery, and I work at the engineering level, not the theme-installer level. I read code, not just docs. Undocumented codebases, raw API payloads, database layers, server configs: all home territory. On the AI side, my sweet spot is where AI meets WordPress. You pick the provider, I write the bridge. I code the integration between your site and the LLM API myself, as a native PHP plugin, with rate limiting, token management, and vector search / RAG pipelines where you need them. OpenAI, Claude, Gemini, or self-hosted models via Ollama: whatever fits your project. If an AI feature outgrows WordPress, I build it as a standalone service in Python (FastAPI, Flask, Django), TypeScript/Node.js, or Go. CORE SERVICES ✅ Custom WordPress and PHP development: plugins built from scratch with clean architecture, custom REST API endpoints, Laravel and CakePHP ✅ Complex debugging: obscure bugs that break after updates and defy standard troubleshooting ✅ Legacy codebase audits: direct code inspection and execution tracing for inherited or undocumented systems ✅ AI integration for WordPress: custom bridge code between your site and the LLM API of your choice, written as a native PHP plugin ✅ Standalone AI services: Python, TypeScript, or Go when your AI feature needs its own engine outside WordPress ✅ Server and Linux administration: deployment, performance, and security from the application layer down to the OS PROBLEMS I GET CALLED IN FOR ✅ "We need a custom plugin built to exact specs. Nothing off the shelf works." ✅ "Our plugin broke after an update and nobody can figure out why." ✅ "We inherited a messy codebase with no documentation and need it untangled." ✅ "We want AI in WordPress (chatbot, semantic search, workflows) without high monthly SaaS plugin fees." ✅ "The AI plugin we bought doesn't support the provider or model we actually want to use." ✅ "We need our server and Linux setup tuned for performance and security." HOW I WORK 1. Written scope before code. You get deliverables, approach, and timeline in writing, so nothing comes as a surprise. 2. Clear updates at agreed intervals. I respond within 24 hours. 3. Documented delivery. You get code you own, with notes your next developer will thank you for. WHY CLIENTS WORK WITH ME • 10+ years of engineering-level depth. I look at code, databases, API payloads, and Linux environments directly, not dashboard settings. • Native and lightweight. Everything lives in clean PHP plugins, no bloated third-party wrappers or fragile workarounds. • Any provider you choose. I write the LLM integration code myself instead of chaining together off-the-shelf AI plugins, so it works with the provider and model you actually want. • Low-maintenance. Hand me an undocumented codebase or a dense API spec and I'll figure it out from the source. • Full stack, literally. Application, database, and server, end to end. If you're looking to build something, fix something, or add AI to your WordPress site, send me a message with a quick summary of what's going on. I reply within 24 hours with an initial assessment.
