THE ENGINEER

I was always the kid who spent most of his time on a computer.
Ten years into building software, I’m still at it.

01 / The beginning 2016—2018 · CureMD

My first years.Real systems.

I joined CureMD as a junior engineer and worked on the claim scrubber—the rule engine used to vet medical claims.

01

Moving the platform forward.

I worked on moving the platform from VB to JavaScript.

02

Putting rules in people’s hands.

Separately, I built an Angular portal where second-level support could create complex rules by adding conditions through a visual interface.

02 / Growing with a product 2018—2026 · Insurify through Arbisoft

I grew withthe product.

At Insurify, my work grew from frontend changes to integrations, architecture, and leading a team of 10. I stayed involved in the code.

A changing frontend

New foundations. An existing product.

I worked on the move from Backbone to React, alongside WordPress-to-Gatsby migrations and new Next.js financial products. The work meant understanding what was already there while building what came next.

03 / Building with AI Turing · Pareto · Insurify

Models enteredthe picture.

I worked on how models learn, built tools to evaluate them, and brought agents into everyday software development.

2024 ↗

Working on the learning side.

Turing / Meta projects

I worked as a secondary delivery lead on supervised fine-tuning and reinforcement learning from human feedback projects—SFT and RLHF.

Reference solutions, evaluation rubrics, calibration, and supporting the people doing the work.

2025 ↗

Building the tools around it.

Pareto / Engineering & delivery

At Pareto, I worked on assessment software and tools for evaluating AI tasks. My contributions covered interfaces, grading, task libraries, and the systems running the work.

2026 ↗

Agents in the development loop.

Insurify / through Arbisoft

I built an agentic development pipeline for Compare Finance: separate agents to plan, implement, test, and review changes, using shared project context and coding rules.

Human review after planning. Validation before the PR handoff.

Along the way Client work & personal projects

Client work.Personal projects.

Alongside the larger team projects, I’ve built business software for clients and made apps and tools of my own.

Accounting software ↗

Client operations, financial documents, and integrations.

Marketplace & operations ↗

Listings, payments, and a connected internal workspace.

Still — app & browser ↗

A native AI assistant and a separate desktop browser. Both in development.

Developer tools ↗

Pull-request review, app-building experiments, and local utilities.

04 / Away from the screen Nigah-e-Ali · Photography

A differentkind of focus.

I’ve always been a National Geographic fan.

Photography was something I wanted to get into long before I could afford it. When I could, I went all in.

It’s how I relax.

05 / The next chapter Still building

Still that kid.Just biggerprojects.

I’m Ali—a full-stack AI engineer who builds software and leads teams. These days, that means product engineering, applied AI, and the systems connecting them.
