What I Do

Three things, done exceptionally well.

I help businesses move faster by building the tools and automations that eliminate bottlenecks.

Retool Development

Custom internal tools, admin panels, and dashboards. A Retool developer since 2021 — from migrating legacy systems to ground-up builds. 50+ apps delivered for teams of all sizes.

AI Automation & LLM Integration

AI-powered workflows using OpenAI, RAG pipelines, and vector databases. Practical AI that ships — document processing, chatbots, and intelligent automation.

Backend & Data Engineering

Scalable Python and Node.js backends, PostgreSQL architecture, data pipelines, and API design. The foundation everything else runs on.

Ali Sajjad Rizavi — Retool Expert and AI Automation Consultant

Builder first, consultant second.

I've been shipping software for over 5 years — from a Y-Combinator startup to enterprise platforms like Glassdoor. I was the kind of engineer who left the desk — visited warehouses, talked to customers in markets — because understanding the problem comes first.

Today I run Radsoft, a consulting practice specializing in Retool and AI automation. I've delivered 50+ applications and helped companies across healthcare, e-commerce, and SaaS move faster with the right tools.

I don't just build what you ask for — I help you figure out what to build.
