Problems we solved
Every system and app on this site shipped with its own hard problem along the way. Here's the honest version — what went wrong, and what we actually did about it.
A client's app pushed live order updates to thousands of devices at once, and notifications started arriving minutes late during peak hours.
Rebuilt the notification pipeline around a message queue instead of direct pushes, so spikes get absorbed instead of dropped or delayed.
A field-service app was unusable in basements and rural sites with no signal — every action just spun and failed.
Moved core actions to write to a local queue first, syncing to the server the moment a connection reappears — the crew never has to wait on signal again.
A business ran its entire operation on a 12-year-old desktop system nobody could safely touch — one crash away from losing everything.
Rebuilt it as a modern web system feature-by-feature, running both side by side until every workflow was verified — zero downtime, zero data loss on cutover.
A multi-language app looked broken in Arabic and Kurdish — layouts, icons and animations were all built assuming left-to-right only.
Rebuilt the layout system to flip direction natively per-language instead of patching styles per-screen, so new screens get RTL support for free.
An e-commerce client kept losing real orders whenever a payment gateway timed out mid-checkout, with no record of what the customer actually paid for.
Added an idempotent order ledger that records intent before the payment call goes out, so a dropped connection can always be reconciled instead of silently losing the sale.
A catalog with tens of thousands of products made search feel sluggish — every keystroke hit the database directly.
Put a dedicated search index in front of the database with debounced queries, cutting result times from seconds to milliseconds.
