Marsharine A. Simpson

React · TypeScript · Python · Instructional Design

I build user-focused web applications and design computer science curriculum, so I understand both how technology works and how people learn it. That combination shapes how I design, test, troubleshoot, and teach.

I build technology. I teach it. I make it easier to use.

A DIFFERENT KIND OF DEVELOPMENT BACKGROUND

I understand what happens when real users get stuck.

My experience across technical support, SaaS, education, and AI evaluation influences how I build. I investigate problems systematically, document decisions clearly, consider accessibility early, and design for people—not only the ideal path.

The implementation supports the claims: clear navigation, responsive layouts, keyboard-accessible dialogs, reduced-motion support, and direct links to working software and source code.

30-SECOND RECRUITER VIEW

Software developer with proof behind the claim.

I build and deploy user-focused web applications, test important behavior, troubleshoot production issues, and document the engineering decisions behind the work.

STRONGEST PROJECT

Student Progress Tracker

React + TypeScript + Supabase/PostgreSQL with authentication, RLS, CRUD, assessment history, dashboard logic, and automated regression coverage.

ENGINEERING PRACTICE

Team-ready workflow

GitHub Issues, feature branches, pull requests, TypeScript checks, linting, testing, production builds, and deployment verification.

PROFESSIONAL EDGE

Clear problem-solving

IT, SaaS support, education, and AI-evaluation experience strengthen troubleshooting, communication, documentation, and user empathy.

30-SECOND RECRUITER VIEW · CURRICULUM + INSTRUCTION

Curriculum designer who can verify every line of code.

I design computer science curriculum end to end—scope and sequence, objectives, scaffolded lessons, assessments, and teacher materials—and I bring classroom teaching and software-development experience to every course.

STRONGEST WORK SAMPLE

Python Foundations

A grades 9–12 course of 7 units and 36 lessons, designed with reference to CSTA K–12 and AP® CSP, with every code example verified on Python 3.12.

INSTRUCTIONAL EXPERIENCE

Elementary through high school

Small-group and individualized virtual instruction at Edmentum, fifth-grade math and science at Charter Schools USA, and CS teaching credentials in New Jersey and Florida.

EDTECH EDGE

Builds the tools, too

Designed and deployed the Student Progress Tracker, a teacher dashboard for assessment history and current mastery by skill.
