About

Enterprise scale by day, full ownership by night.

I am Andrew Persad, a lead software engineer at Deloitte Digital. For the last several years I have built front ends for Fortune 500 platforms while shipping my own products end to end on the side. The two habits feed each other: client work teaches scale and restraint, my own products teach what it costs to own every decision from schema to pixel.

Experience

fig. 01 / lead software engineer, Deloitte Digital

At Deloitte Digital I build accessible, responsive interfaces from high and low fidelity designs, and I build the systems behind them: a white-label component library and internal design system created from scratch, starter kits that made quality repeatable across client teams, and performance work measured in render profiles rather than vibes.

    Hewlett Packard / Workforce Experience Platform

    I lead delivery of the web portal IT administrators use to watch fleets serving 9 million users: device telemetry, remote script remediation, policies, and engagement pulses. I architected the modular React front end on HP’s Veneer design system, with enterprise SSO and WCAG-compliant accessibility, and worked directly with the data team to turn raw fleet telemetry from the data lake into APIs the portal could render in near real time.

    Eli Lilly / Consumer site redesign

    I led frontend efforts on the full redesign of the consumer-facing site, 150K to 200K monthly active users, including a new medicine exploration and pricing experience. Along the way I contributed to the relaunch of the Lilly Design System and wired external APIs and CMS content into responsive UI flows: LillyDirect, conditions pages, the healthcare provider page, and authentication.

    Amazon / Buy with Prime

    I helped launch the Buy with Prime merchant portal: the product listing and order management dashboards, built on Amazon’s Meridian design system, that gave 9 million+ vendors one place for centralized insights.

Off hours

fig. 02 / the other half

Evenings and weekends go to products I design, build, run, and answer for myself. Five are shipped and live right now: a group decision app, a calendar overlap finder, a payroll engine that files real forms for my own household, a pet medication tracker, and a nutrition calculator that ships as both a React web app and a native SwiftUI app. None of them are demos. They have users, uptime, and consequences, which is exactly why I keep building them.

These projects are where I take the risks client work cannot: HMAC-signed guest sessions instead of forced accounts, recurrence math pushed down into Postgres, OCR that runs on-device so photos never leave the phone. The ones that survive contact with real use become the case studies on the work page.

The portrait on this site is part of the same discipline. It is a hand-built vector redrawn from my old avatar art, flat color with no shading, and it reads its palette from the same design tokens as every other element on the page. Flip the theme and it changes shirts.

If this sounds like the kind of engineer your team is missing, the contact page is the fastest route. I reply within a day or two.
