Alessandro Paolo Alghisi

Senior Full Stack Engineer

Eleven years of production work, almost all of it full stack: React and TypeScript on the client, Node.js and Python on the server. I interned twice at Google. At Sector Labs I was on the small team that built Bayut and Zameen from an empty repository to millions of monthly users. For the last three years I have also shipped retrieval, copilots, and agent workflows.

Cluj · Remote

Senior Full Stack Developer

Independent

Android and iOS field-service apps for Firese, a national fire-protection and maintenance company: a live GPS view of every technician, and defect photos filed to the right client with location and timestamp. Backend and storage on AWS. The apps are private and confidential, so I cannot publish them. Client sites in React, TypeScript, and Node.js.

Senior Full Stack Developer

Raw Geeks

Lead engineer for product and AI features on React, TypeScript, and Node.js. I led the AngularJS-to-React migration and took part in architecture decisions.

  • Chat copilots, search, and content generation with the Vercel AI SDK (OpenAI, Gemini): streaming, tool calling, and structured JSON.
  • Retrieval on pgvector and Pinecone, with a prompt-evaluation harness so answer quality stayed stable between releases.

Milan · Hybrid

Senior Full Stack Developer

Complaion

FastAPI services on PostgreSQL, and React and TypeScript front ends, for a platform that takes companies through ISO certification. OAuth with Google and Microsoft Entra ID. File sync with OneDrive, SharePoint, and Google Drive.

  • A document pipeline that extracts and classifies regulatory text against strict JSON schemas, with a person still in the review loop.
  • Tool calling so compliance officers can query policy in plain language.

Senior Video and Full Stack Consultant

Independent

  • Built Collab, a video-meeting app in React and React Native (Expo) over WebRTC, with a shared Monaco editor and a run button for JavaScript, TypeScript, Python, Go, and C++.
  • Zoom Video SDK and Cisco Webex proofs of concept, including the SOC 2, licensing, and scale comparison.
  • Retrieval and LangChain agents that cut a client’s support response time by about 60 percent. A React server-rendered redesign that lifted engagement by about 50 percent. Adobe Experience Manager components (HTL, Sling, OSGi).

Full Stack Engineer

Sector Labs · Bayut, Zameen

One of a small senior team that built Bayut, Zameen, and other property portals from scratch and scaled them to millions of monthly users.

  • Led the React, Redux, and TypeScript front end, including server rendering, bundle size, and Redis on the hottest pages.
  • Node.js and Django services on PostgreSQL, MongoDB, and AWS.
  • Kept a PHP and Laravel platform in production while it moved to Node.js, Python, and React.

Earlier

  • Hewlett Packard Enterprise. LoadRunner’s C++ web-protocol engine. Cookie and session bugs traced with Wireshark. About a 25 percent gain in protocol handling.
  • Google, Logs. Mountain View. A release check that decides whether a logging policy is safe to ship, wired into Google’s release framework. A logging prototype about 15 percent faster.
  • Google, Chrome. Kitchener. Pinch-to-zoom for the built-in PDF viewer, in C++ and JavaScript. Still in Chromium: codereview.chromium.org/1881603002.
  • Algotech Solutions and Yardi Systems, Cluj. First production React and Node.js, then Perl tooling for property data.

Selected work

Collab

github.com/alexalghisi/collab · 2024–2025

Video meetings with a shared, runnable editor. One React Native codebase for web, iOS, and Android. Google sign-in, a calendar, live cursors in Monaco, and a hosted compiler for five languages.

Chrome PDF pinch-to-zoom

Google Chrome · 2016

Touch handling and the transform that keeps the point under the fingers fixed while zooming. Landed with the Chrome touch-events team across renderer IPC, PPAPI, and the public C++ API. Code review.

A11yDojo

github.com/alexalghisi/A11yDojo

Training for three WCAG failures that show up constantly in generated interfaces: missing names, heading order that follows font size, and focus that escapes a dialog. The pass rules are pure functions, covered by Vitest and Playwright.

AgentTower

github.com/alexalghisi/agenttower

Traces and cost for agent runs: model, tools, tokens, latency, and a step timeline. Next.js, TypeScript, Drizzle, PostgreSQL.

PDF editor and dual-pane explorer

pdf-editor · react-modern-drag-and-drop

A React Native editor that rewrites the PDF content stream, so text and images stay real objects. A Finder-like explorer whose folder rules and keyboard behavior live in tested functions, not in the drag library.
