PROJECTS AT MONI LLC
IMS | Internal System for Managing Blogger Partnerships 2026
• Developed and deployed IMS, which collects Telegram and Instagram conversations, tracks deals through a 15-stage
pipeline and syncs with KeyCRM and a Google Sheets tracker. Runs with Docker Compose and nginx, with
PostgreSQL, Redis queues (BullMQ) and S3-compatible file storage (MinIO).
• Built the Telegram and Instagram (Meta API) integrations with API rate-limit handling, background jobs and automatic
catch-up after downtime. Imported ~1,500 conversations, 160,000 messages and migrated 20,000+ customer cards from
KeyCRM.
• Implemented role-based access, 2FA by email, brute-force protection, encrypted secrets, request rate limiting, file access
by permissions and an audit log. Masked card and passport numbers before data went to the AI model.
• Covered the system with 2,000+ Jest tests, with a mandatory check before every release.

MySQL tables, so recognition errors do not reach the data. Tests run in Docker.

OTHER PROJECTS
