John R. Molina

Software Engineer Python, C++, SQL, and Full-Stack Web

I build practical software for data-heavy workflows, backend services, and responsive web applications. My strongest fit is a software engineering role where Python, SQL, APIs, and clear debugging matter.

My background combines a B.S. in Computer Science with hands-on experience supporting enterprise data systems, maintaining workflows across 5M+ records, and translating stakeholder needs into reliable technical deliverables.

Recent projects include a Django/React portfolio platform, a Next.js/PostgreSQL storefront, and systems/data projects that show how I approach testing, documentation, and iteration.

Where I Fit Best

Backend and data workflows

SQL, Python, ETL validation, reporting, and database-backed applications where correctness and repeatable process matter.

Full-stack implementation

Django, REST APIs, React, Next.js, TypeScript, PostgreSQL, Docker, and Git-based workflows for shipping user-facing tools.

Technical ownership

Requirements gathering, issue triage, validation, documentation, and communicating technical tradeoffs to non-technical teams.

Professional Experience

Columbia University, Office of Alumni & Development

Development Assistant, Data Management Group | 2017-2022

Supported data quality, ETL workflows, reporting, and platform maintenance for advancement systems serving 5M+ constituent records, including weighted deduplication workflows for academic affiliation data.

Built a weighted matching workflow for deduplication efforts, scoring candidate records across name, demographics, employer, email, address, spouse, and degree data.
Developed SQL views, stakeholder reports, BI dashboards, and spreadsheet review processes for duplicate prevention and manual data review.
Resolved 10,000+ Salesforce-tracked data service inquiries while coordinating with IT, administrators, developers, vendors, and non-technical stakeholders.

Projects

Portfolio Website Platform

Full-stack portfolio and blog platform built with Django 6.0, Django REST Framework, React, Wagtail CMS, and Docker. Implemented structured content management, API workflows, security controls, and automated tests for page behavior and edge cases.

Fusion Manaba

Full-stack e-commerce application for a small business, covering product catalog, cart state, checkout flow, relational data modeling, and third-party payment and email integrations.

Client/Server Chat System

Multithreaded client/server chat application using TCP/IP sockets, persistent connections, custom message parsing, concurrent client handling, and JUnit coverage for reliability.

Global Economic Impact Analysis

End-to-end Python data pipeline ingesting and normalizing Bloomberg, SIPRI, and World Bank datasets, then producing visual analysis of military spending and market behavior across countries and time periods.

About

I am a New Jersey/New York based software engineer pursuing software engineering roles in backend, full-stack, application, data engineering, and QA automation-adjacent teams.

Before moving fully into software engineering, I built practical technical judgment in data management roles: writing SQL and Python batch tools, supporting ETL and migration work, maintaining reports and dashboards, resolving 10,000+ Salesforce-tracked data service inquiries, and collaborating with IT, administrators, developers, vendors, and non-technical stakeholders.

That background makes me strongest in engineering environments where the work touches real users, messy data, APIs, internal tooling, validation, and careful communication. I am continuing to sharpen my fundamentals through MIT 6.006, CLRS, and project work in Python, JavaScript/TypeScript, C/C++, and SQL.
