Alvin Sakhiya

I'm a software developer based in London, working across full-stack web development, cloud platforms and embedded machine learning.

My background in community pharmacy has shaped how I approach software: I care about accuracy, clear workflows, data protection and building systems that are genuinely useful in day-to-day work.

Selected projects

A full-stack pharmacy operations platform built with React, TypeScript, Django REST Framework and PostgreSQL.

The system brings together:

  • stock and batch management
  • FEFO expiry review
  • dosette and MDS workflows
  • operational reports
  • audit logging
  • role-based access
  • backup and restore
  • explainable stock forecasting and transfer suggestions

The project uses fictional demonstration data and is designed as an operational prototype, not a clinical system.

An on-device TinyML prototype for detecting fall-like events using an Arduino Nano 33 BLE Sense Rev2.

It combines accelerometer and gyroscope data with Edge Impulse inference, hybrid motion checks, inactivity verification, a cancellable alert countdown, BLE status updates and a Streamlit monitoring dashboard.

The final binary model achieved 93.41% model-testing accuracy. The project is an engineering prototype and is not presented as a medical device.

A cloud-hosted multimedia asset management platform built around Microsoft Azure services.

It includes media uploads, metadata management, search, filtering, CRUD workflows, responsive previews and automated deployment.

The project uses:

  • Azure App Service
  • Azure Blob Storage
  • Azure Cosmos DB
  • Azure Logic Apps
  • Application Insights
  • GitHub Actions

Technologies

Frontend

React, TypeScript, JavaScript, HTML, CSS, Tailwind CSS, Bootstrap

Backend

Python, Django, Django REST Framework, REST APIs

Data and infrastructure

PostgreSQL, Docker, Microsoft Azure, GitHub Actions, CI/CD

Embedded and machine learning

Background

I completed a BSc (Hons) in Computing Systems at Ulster University.

Alongside software development, I work in community pharmacy as a Pharmacy Dispenser and Vaccinator. This gives me practical experience of patient-facing communication, confidentiality, stock management, medicine workflows and accuracy-critical processes.
