About · Addis Ababa

I build backends where latency is the product.

Most of my work is the unglamorous kind — finding the query that blocks the event loop, the cold start nobody budgeted for, the index that was never added. The interesting part is not the fix, it is knowing which number moved and by how much.

    Chose AWS ECS Fargate over Lambda for real-time infrastructure to eliminate cold starts. Built a WebSocket notification pipeline holding p99 under 100ms, with automated testing behind 99.9% uptime.

    Full-stack Engineer · Wedlii

    Built wedlii.com.au on server-rendered Next.js for search visibility, and integrated Stripe Connect for multi-party payments with compliance-grade integrity.

    Moved a legacy backend to Next.js and Drizzle with zero downtime, then cut query latency 30% through indexing and query planning.

Methodology

Status · sample data

TODO — these samples are seeded, not measured. They exist so the trace has a shape while real data is sourced. Replace with this site’s own TTFB or Core Web Vitals samples and uncheck "illustrative" once the collection method can be described here honestly. Until then the hero labels them as sample data.

Budget: 50ms. Samples: 48. Any sample above the budget renders in amber on the trace; if nothing breaches, no amber appears anywhere on the site.
