I'm Canaan, a Human existing on earth who's into computer wizardry.
Backend engineer in Amman, Jordan. Currently at Shory, working on UAE motor-insurance platforms that talk to Abu Dhabi Police services and a network of insurance companies. C#, Redis, SQL Server, Hangfire. Rust when nobody is looking.
API quota governance, twice. Redis with Lua scripts doing atomic per-company counting across 11+ endpoints, then torn down and rebuilt as a configurable service-category × time-period model. Progressive alerts at 70 / 85 / 95 / 100%, with Hangfire-driven deduplication so one bad afternoon doesn't page anyone four hundred times.
Two breaking-change API migrations, zero broken integrations. Field renames, data type changes, deprecated attributes removed, request bodies restructured — across the externally exposed surface. Every integrated insurance company survived. This is the one I'm smug about.
Monthly credit note generation, whole vertical slice. Migrations and stored procedures, PDF generation, Hangfire orchestration with write-back, finance reporting with transaction-level drill-down, and tests covering eligibility, aggregation, numbering, and the failure paths nobody writes tests for.
PriceMonitor (@ Equiti). Real-time FX pricing alerts over SignalR and MassTransit/RabbitMQ — ingesting live MT4 and PXM feeds, matching configurable thresholds, fanning out to concurrent trader sessions.
A gRPC service wrapping MetaTrader 5 (@ Equiti). 10+ RPC endpoints for positions, orders, deals and trade history. Docker, Kubernetes, Helm, Azure DevOps.
A home server that has survived me. 15+ self-hosted services on Docker Compose, NVIDIA GPU passthrough, Tailscale, LVM, automated drive mounting. Jellyfin and Immich are the load-bearing ones.

kanaan.dev — around fifty writeups. Keyset vs offset pagination. The .NET dispose pattern. Database partitioning. CAP theorem. Static search with no service behind it. Why I started drawing.
Some of them are about code.
Currently learning: Rust, maths, and how to stop starting new repositories. Progress on the third is disputed. (⊙_⊙)？
