What I Do

Backend & API Engineering
Laravel and Django backends, RESTful APIs and microservices for production SaaS. Multi-tenant workspaces, roles and permissions, queues and background jobs, and subscription billing.
Real-time Systems
Real-time messaging built from scratch on WebSockets (Laravel Reverb), plus queue-based pipelines that deliver thousands of messages a day.
AI Automation
Self-hosted n8n workflows connected to the OpenAI API, powering AI workers that reply to conversations and automate follow-ups, wired into the core app through webhooks and APIs.
Cloud & DevOps
AWS (EC2, S3, RDS, Lambda) and DigitalOcean. Linux hardening, Nginx, SSL, DNS, VPNs and Proxmox, CI/CD with GitHub Actions and GitLab CI, and monitoring with CloudWatch and Laravel Nightwatch.
Full Stack Web & Mobile
Next.js and React front ends with TypeScript, and backend APIs for Android apps with over 1 million downloads, scaled for high traffic.
Technical Leadership
Led a team of 4–5 developers and owned production reliability and the engineering process: sprint planning, architecture and database design, code reviews and releases.
