Recently, I completed a server-side conversion tracking system that connects Meta Ads, LINE Official Account, and n8n automation workflows. The system captures actual LINE friend additions and sends them directly to Meta through the Conversions API (CAPI), significantly improving attribution accuracy. Unlike traditional browser-based pixel tracking, this architecture is resilient to ad blockers, cookie restrictions, and browser privacy changes. Using n8n enabled rapid development, lower operational costs, and easier maintenance compared to building and managing a custom backend service. The workflow integrates webhooks, event processing, data transformation, and Meta server-side event delivery in a scalable architecture. This approach helps advertising campaigns optimize toward real business outcomes rather than simple page visits or button clicks. I specialize in building automation-driven systems that combine AI, APIs, cloud infrastructure, and marketing technology into production-ready solutions.

I'm currently available for freelance projects, contract work, and full time software engineering roles. Over the past few years, I've worked with startups and companies building AI powered products, web platforms, mobile applications, automation systems, chatbots, and voice AI solutions. My experience spans the entire product lifecycle from planning and architecture to development, deployment, and scaling. Some of the areas I've worked in include: • AI agents and multi-agent systems using LangGraph, AutoGen, CrewAI, and ReAct • Generative AI applications powered by OpenAI, Claude, DeepSeek, and Hugging Face • RAG systems, AI assistants, and custom chatbot solutions • Voice AI and IVR platforms using Vapi AI, Retell AI, and Twilio • Workflow automation with n8n, Zapier, Make.com, and custom API integrations • Full-stack web development with Next.js, React, and Vue.js • Cross-platform mobile development with React Native and Expo • Computer vision, OCR, AI avatars, and media-generation applications Tech Stack: Python, TypeScript, JavaScript, Next.js, React, Vue.js, React Native, LangChain, LangGraph, OpenAI, Claude, DeepSeek, Hugging Face, n8n, Zapier, Make.com, Twilio, Vapi AI, and Retell AI. I've had the opportunity to work on projects for companies across a variety of industries and collaborate with distributed teams in different parts of the world. I'm comfortable working across time zones and can provide overlapping hours with teams in North America, Europe, and Asia. If you're looking for an engineer who can help build, launch, or scale AI products, web applications, mobile apps, or automation solutions, I'd be happy to connect. Feel free to send me a message I'd love to learn more about your project or team.
