SYS.STATUS: OPEN_TO_WORK//JENIN, PALESTINE

Hi, I'm Tareq Ali

> I build full-stack web apps▍

Software engineer and Computer Science graduate who builds end to end: web apps, APIs and services, databases and desktop software. I work with modern AI tools to ship fast, and I care about what makes software trustworthy: measuring performance, testing, and clear documentation.

Featured projects

ReplayPad soundboard window: a dark UI with a grid of colored sound pads and category chips

P-01 Windows desktop app · C# / WPF

ReplayPad

A soundboard that records its own material. It keeps the last minutes of your PC's audio in RAM; one hotkey saves the moment as an MP3, you trim it in the built-in editor, and it becomes a pad you can fire into a Discord call.

  • Audio engine: rolling in-memory replay buffer (1 to 30 min) with whole-desktop, per-app or "everything except one app" capture via Windows process loopback.
  • Editor: waveform with range handles, cut, fades, normalize, undo and effects, with safe saves that can never destroy the original file.
  • Cloud backup: Google Drive backup and restore with OAuth and the minimal drive.file scope, plus scheduled automatic backups.
  • Extras: global hotkeys, quick launcher, speech-to-text transcripts synced to playback, and a self-contained installer with an update checker.

P-02 Internship final project · TypeScript / PostgreSQL

LogService

A structured log ingestion, search and aggregation service, a simplified Datadog or Grafana Loki. Apps POST batches of logs; the service stores them durably and makes them filterable and aggregatable, all inside a 0.5 CPU / 256 MB container.

  • Raw SQL, no ORM: one INSERT … unnest per batch, a ~33 µs CPU budget per log, and partial-batch validation that reports each rejected entry.
  • PostgreSQL design: daily partitions with automatic retention, cursor pagination, attribute filtering, and per-minute rollups for aggregation.
  • Measured, not guessed: found the bottleneck with EXPLAIN, wait events and WAL-per-row sampling, raising throughput 3.5x and cutting aggregate latency under load ~34x.
  • Reliability: fixed a rollup deadlock the benchmark couldn't see, and verified with a one-hour soak that every acknowledged write stays queryable.

ReceiptLens spending dashboard: monthly spending bars and spending by category

P-03 Full-stack AI web app · .NET / Next.js

ReceiptLens

Snap a photo of a receipt and AI fills in the store, date, total, category and line items. You check it, save it to your account, and get a spending dashboard by month and category. A one-click demo account lets anyone try it without signing up.

  • AI extraction: Google Gemini with a strict JSON schema, then server-side validation that repairs bad dates, prices and categories and rejects photos that aren't receipts.
  • Backend: ASP.NET Core minimal API with Identity bearer-token auth, per-user data in PostgreSQL via EF Core migrations, and per-visitor rate limiting to protect the free AI quota.
  • Frontend: Next.js and React with in-browser image downscaling, an editable receipt view, and a responsive dashboard in light and dark themes.
  • Quality: integration tests against a real PostgreSQL database and CI on every push; deployed on Vercel, Render and Neon.
