Most small teams don’t need a bigger agency. They need one person who can build the website, wire up the data, and explain the numbers in plain English. That’s the job.

Services

What I build

WEB

Custom web applications

Internal tools, portals, and client-facing apps built with React, TypeScript, and FastAPI. Logins, dashboards, workflows, and integrations with the systems you already use, including Microsoft 365 and SharePoint.

  • React 19
  • TypeScript
  • Vite
  • FastAPI
SITE

Websites & online stores

Fast, accessible, search-friendly websites and storefronts for businesses and public organizations, deployed on Cloudflare Pages or Netlify. WCAG 2.1 AA as a baseline, not an upsell.

  • Next.js
  • E-commerce
  • Accessibility
  • SEO
AI

AI search & LLM applications

Search that understands what people mean, and AI agents that follow your business rules. Hybrid keyword and vector retrieval, with an independent validator checking every answer before anyone acts on it.

  • Azure OpenAI
  • AI Search
  • Claude API
  • Agents
PIPE

Data pipelines & analytics

Automated pipelines that pull data from databases, spreadsheets, and APIs, clean it, and land it somewhere reliable on a schedule. No more copying and pasting.

  • Python
  • R
  • SQL
  • Snowflake
DASH

Dashboards & data visualization

Dashboards people actually open. Clear charts, the few numbers that matter, and drill-downs for when someone asks “why?”

  • Shiny
  • React
  • D3
  • Posit Connect
ML

Forecasting & machine learning

Demand and energy forecasts, anomaly detection, and predictive maintenance. Models are cross-validated, chosen automatically per segment, and come with honest uncertainty ranges and plain-language explanations.

Process

How a project runs

Five steps, the same for a one-page website or a forecasting system. You always know what happens next.

  1. 01Discover

    A free call to understand the problem, the people involved, and what success looks like. You get a written scope and a fixed quote.

  2. 02Design

    Wireframes and a clickable prototype before any production code, so changes are cheap and nobody is surprised.

  3. 03Build

    Short cycles with a live preview link. You see progress every week, not just at the end.

  4. 04Launch

    Testing, accessibility checks, analytics, and a calm launch. Domains, hosting, and handoff handled.

  5. 05Support

    Optional monthly care plans for updates, monitoring, and small improvements. You always own the code.

About

Hi, I’m Abdel.

Headshot of Abdel Ali in a gray suit and green tie
Abdel Ali · Owner & Lead Developer

I’m a full-stack developer and data scientist based in Kenosha, Wisconsin, and the person behind Apps By Abdel.

By day I’m a Data Science Analyst II in manufacturing. I started on the IT customer experience team, moved into data science as an intern, and was promoted twice. I build forecasting systems, predictive-maintenance models, AI-powered inventory matching, and the pipelines and dashboards around them.

On the side I build websites, online stores, and apps for local businesses. Same rigor, smaller scale, and you get to talk to the person writing the code.

I earned my B.S. in Computer Science from the University of Wisconsin–Parkside and have been admitted to Purdue’s M.S. in Applied Statistics.
