Over the past 8+ years, I’ve been building and scaling production-grade software for startups and growing companies. My background is in full-stack engineering with a strong focus on backend architecture, distributed systems, and real-time infrastructure. I primarily work with Node.js and TypeScript, building modern applications with React, Next.js, and PostgreSQL, while designing systems that can reliably handle real users and real business workflows. In recent years, I’ve focused heavily on AI-driven products and automation. I design and implement conversational agents, voice AI systems, and workflow automation that help companies reduce manual work, respond to customers faster, and operate more efficiently. I’ve worked with tools and frameworks like LangChain, LiveKit, Twilio, n8n, and custom LLM pipelines to build practical AI systems that deliver measurable business value. I typically work closely with founders and small teams, helping turn ideas into working products, improving existing systems, and building the technical foundations needed to scale. My approach is very execution-focused — understanding the business goal first, then building the simplest and most reliable system to achieve it. I’m currently open to new opportunities and collaborations with founders and teams building ambitious products, especially where AI, automation, and scalable infrastructure can create real operational impact. If you’re building something meaningful and need someone who can take ownership from architecture to production, I’d be happy to connect.

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.

Hi everyone! Great to meet y'all and very happy to be part of this community that will hopefully guide me on my way in the AI & Automation space. My goal is building a Voice AI & Automation Agency and being part of this fascinating industry that will be the future of streamlining business workflows and human interaction with computers. I'm very excited about the journey! Looking forward to good conversations - feel free to reach out!
