Description
As the lead engineer for the landing page and sales-AI initiative at HiliosAI, I architected the full-stack solution leveraging Next.js for Server-Side Rendering (SSR) / Static Site Generation (SSG) and FastAPI microservices to manage content hydration, lead data processing, and AI agent responses.
I embedded an AI-powered conversational assistant that handles FAQs, captures email/phone/summary leads, and routes qualified prospects to demo scheduling — seamlessly integrated into the landing page experience.
On the backend I built REST and GraphQL endpoints for real-time lead tracking, integrated with CRM APIs (HubSpot) and orchestrated Slack + n8n workflows to notify sales teams immediately when high-intent interactions occur.
The system is containerised using Docker, deployed on AWS infrastructure, and includes monitoring via Langfuse to track AI prompt latency, failure rates, and lead-conversion metrics — enabling data-driven optimisation of the agent and the funnel.
Through this project I deepened my expertise in modern web frameworks (Next.js, React), full-stack API design, AI agent observability, lead-qualification workflows, and high-performance deployment environments.
