Linkforge
Multi-tenant SaaS · Link-in-bio & Real-Time Analytics
I built the core backend and analytics infrastructure that powers Linkforge. From tenant isolation and event tracking to analytics aggregation and secure username management.
What is Linkforge?
Linkforge is a developer-centric link-in-bio and real-time analytics platform built from scratch with an emphasis on resilient backend fundamentals before applying abstractions.
While surface-level bio tools present simple lists of links, the underlying architecture must support multi-tenant database partitioning, race-condition-free vanity slug changes, fail-fast configuration checks, and high-throughput async event logging.
Engineering Highlights
04 Core PillarsMulti-Tenant Data Isolation
Tenant-scoped database partitioning
Strict tenant context enforcement at the middleware and query layer ensures complete logical separation across user accounts and organizations with zero cross-tenant contamination risk.
Atomic Slug & Username Mutations
Optimistic locking & transactional safety
Database-level unique constraints combined with interactive transaction rollbacks eliminate race conditions when vanity slugs or usernames are renamed concurrently.
Fail-Fast Environment Diagnostics
Zod-powered startup validation
All runtime secrets, database connection URIs, and port bindings are validated via a strict schema at boot time, preventing silent mid-request runtime crashes in production.
Asynchronous Event Tracking
Decoupled redirect & analytics pipeline
Visitor clickstream events, geolocation telemetry, and referrers are dispatched asynchronously, maintaining sub-millisecond redirect speeds on the critical path.
