I’m opening up bandwidth for a new project or long-term collaboration. I’m a senior full-stack engineer focused on building real, production-ready systems — not demos. My core strengths are: • Full-stack web apps (React / Next.js / Node / TypeScript) • AI agents & LLM workflows (chat, tools, RAG, multi-agent) • Voice AI (real-time calls, scheduling, assistants, call handling) • Automations & integrations (n8n, Make, CRMs, internal ops) • Scalable backend infrastructure and clean architecture I typically work with founders and teams who need someone that can think end-to-end: product, system design, reliability, and speed of execution. If you’re building something ambitious and want to move fast without cutting corners, feel free to DM me. Happy to review ideas, audit existing systems, or jump straight into execution.

Hi everyone,I’m Marek Lucien, a full-stack engineer and AI automation builder based in Singapore. My background spans eight years across backend systems, real-time infrastructure, and frontend engineering, but my core focus today is building production-grade AI agents. Most of my recent work has been around voice agents, conversational workflows, and multi-channel automation. I build systems that handle scheduling, customer support, follow-ups, data processing, and end-to-end task execution across voice, chat, email, and internal tools. My experience includes VAPI, Twilio, LiveKit, LangChain, pgvector, n8n, and custom agent logic that connects deeply with business workflows. Right now, I’m exploring a new opportunity where I can help a team or founder design, build, and deploy reliable AI systems at scale. I enjoy projects that require strong architecture, clean execution, and fast iteration. If you're working on voice AI, support automation, or agent-driven operations, I’d love to connect.
