At Orotron, I build a production multi-tenant SaaS platform spanning volunteer management, CRM, memberships, fundraising, and events across 50+ business modules.
I've designed large-scale REST APIs in Node.js and TypeScript, architected normalized PostgreSQL schemas with zero-downtime migrations, and implemented JWT, Argon2, OAuth 2.0, TOTP-based MFA, and RBAC. I also integrated Stripe Connect, AWS S3, Firebase Cloud Messaging, Brevo Email, Redis, and Upstash QStash for payments, storage, notifications, caching, and background jobs.
For LINC Digital, I delivered GDPR-compliant consent management, audit history, contact timelines, and a real-time chat service using Centrifugo, PostgreSQL, and Redis.
I've containerized backend services with Docker, deployed them on AWS ECS Fargate through GitHub Actions CI/CD, and collaborate closely with frontend, QA, and product teams throughout sprint delivery.
