Christian Bert T.
Full-Stack Developer | React, Next.js, Node.js, AI Integration
I build web and mobile apps that are production-ready, not just functional. 3+ years of full-stack experience across fintech, AI SaaS, and business automation. I've worked on real products with real users: an international money transfer platform (Bless Payments), an AI video editing product (Plot, at Butter Studio), and an internal operations platform for a business under NDA. I know what it takes to ship and maintain code at scale. What I can help you with: ✦ Web apps: React, Next.js, TypeScript, Tailwind CSS ✦ Backend: Node.js, Express, Python, FastAPI, .NET/C# ✦ Mobile: React Native (certified) ✦ AI integration: Claude API, MCP, OpenAI, AssemblyAI ✦ Integrations: Stripe, Veryfi OCR, QuickBooks, Gmail, and private APIs with no docs ✦ Database: PostgreSQL, Supabase, SQLite, Drizzle ORM ✦ Infra: Docker, Azure, GitHub Actions, DigitalOcean At Bless Payments I built authentication systems, payment gateway integrations, and verification workflows for an international remittance platform: security-first, cross-timezone, production-grade. At Butter Studio I led full-stack development of an AI video editing SaaS from the ground up: transcription pipelines, AI story extraction, EDL/FCPXML export, and proxy file workflows. Plot also runs as a native DaVinci Resolve plugin and an MCP server that works alongside Claude. The AI picks sentence numbers instead of writing prose, so it can't invent a quote. I'm easy to work with. I communicate clearly, raise blockers early, and I don't disappear mid-project. Whether you need someone to own a feature end-to-end or collaborate with an existing team, I'm comfortable either way. Let's talk about your project.
