Cloud & DevOps engineer (AWS, Kubernetes) and app developer
Niyyah: a prayer companion app I designed, built and shipped end to end for iOS and Android. Prayer times with adhan reminders, duas and home-screen widgets, in 10 languages. Free on the App Store and Google Play. Open source: fix merged into Apache Superset. I hit this bug in a production deployment: CSV exports ignored the configured encoding after Werkzeug 3 removed Response.charset, so Excel garbled every non-ASCII character. I traced the root cause, fixed the response class so the configured encoding is applied explicitly, and got it reviewed and merged upstream (apache/superset#40801). Monthly AWS cost report in Slack: an open-source Lambda I wrote that compares the last 30 days of AWS spend with the 30 days before and posts a short summary to Slack, with threaded detail on per-service changes, Reserved Instance health and Savings Plans coverage. One Lambda, one cron, one channel. Python 3.12, MIT licensed. AWS start/stop scheduler: an open-source tool I wrote that starts and stops tagged AWS resources on a schedule, so dev and test environments aren't billed around the clock. Two Lambdas handle EC2, RDS, Aurora/DocumentDB/Neptune clusters and ECS services; you tag a resource and set a start and a stop cron. github.com/Bungic/aws-start-stop-scheduler
