Full-stack developer building AI-powered web apps with Next.js, TanStack Start, React, and Cloudflare.
I'm a developer in the Philippines (UTC+8). I've been building and running websites for over ten years. I started with WordPress and SEO, and these days I mostly build TypeScript and React apps with AI features, deployed on Cloudflare. I work through my registered business, Edventure Web Development Services, and I run my own sites and apps too, so I handle hosting, monitoring, and search traffic after launch.
- AI features in web apps: chat, document search (RAG), OCR, structured data extraction, and tool-using agents on Claude, OpenAI, Gemini, DeepSeek, GLM, and Mistral models.
- Apps on Cloudflare: Workers, D1, R2, KV, Durable Objects, Workers AI, and the Agents SDK. They run close to users worldwide and cost little to host.
- Full-stack React: Next.js, TanStack Start, and React Router apps with Clerk auth, TanStack Query, Hono APIs, Drizzle, and Zod.
- Python tools: scripts, bots, and small services built on the Anthropic and Google Gen AI SDKs.
- Content sites that rank: Astro and WordPress sites built with Core Web Vitals, structured data, and technical SEO in mind.

I take freelance and contract projects: new builds, adding AI features to an existing product, moving an app to Cloudflare, or fixing performance and SEO problems. Email support@edventure.com.ph or DM @markllego with a short description of what you need.
When I'm not working, I cook, spend time with my family, and play Ragnarok Online.
