• Built an end-to-end session replay and RUM platform in a monorepo: a TypeScript browser SDK using rrweb recording, a Go/Fiber ingestion API, PostgreSQL storage and a React dashboard.
• Engineered a high-throughput ingest pipeline — handler to in-memory queue to goroutine worker pool — with size and time-based batching, bulk inserts and idempotent writes for reliability under load.
• Developed a React dashboard for project and session management with rrweb replay, integrated via dedicated ingestion dashboard API routes.

• Built a lightweight, single-node message broker in Go with a disk-backed queue, targeting a low memory footprint and high throughput for local and embedded-style workloads — similar goals to Kafka or RabbitMQ at a much smaller scale.
• Storage: designed a custom write-ahead log with rotating segments, memory-mapped reads for hot data, CRC32 record integrity and an atomic offset index for crash-safe recovery and fast lookups.
• Wire protocol and concurrency: implemented a framed binary TCP protocol with no HTTP or JSON on the wire, and a concurrent server using goroutines, channels and mutexes to multiplex many producer and consumer connections with explicit context-driven lifecycles.
