Technologies: Node.js, React, Panther API, ServiceNow API, Confluence API, Jira API, PyTorch. - Retainr.ioPrinciple Lead EngineerAGENCE & SSIIjuin 2024 - janvier 2026 (1 an et 7 mois)I lead infra, native mobile, Web, backend, API, security, and technical direction in all the projects that my SaaS takes as well as any major decision-making tasks. Great time management is crutial here.Focus on AI features using OpenAI and Claude integrations.The client site is built with Webflow (I’ve been using Webflow for years and it is now my go-to tool for front websites).Frontend is React with Mantine UI components library.API stack is NestJS with MongoDB as the chosen NoSQL database.SendGrid API, and with about thirty dynamic templates created there.Using Webflow API with OpenAI’s API to generate blog articles based on freelance topics and get published atBuilding a Zapier App to allow automation across the Retainr.io products. And use Zapier CLI to maintain the custom Zapier app easily through GitHub.The native apps (iOS & Android) are built with React Native (Expo).All subdomains and whitelabel custom domains are generated and deployed through Nginx. They are issued with Certbot and run as a cron job for certificate renewals.Due to infrastructure restrictions on the current AWS EC2 instance, I am using PM2 to run Node.js directly on the instances. A good amount of AWS services are used for Retainr, including ACM wildcard certificates and CloudFront distributions, alongside Cloudflare DNS. I am a big fan of Cloudflare, which helps ensure consistent availability, fast load times across the globe, and a strong level of security.
