Hi, I’m Jeremiah Haremza πŸ‘‹

I'm a data professional specializing in backend automation, API integration, and database-driven solutions.
I build tools that connect, analyze, and automate systems β€” often with Python, SQL, and Postgres.

I'm equally fluent in explaining technical decisions to non-technical stakeholders.

My projects emphasize reliability, modularity, and real-world application.

πŸ”§ See my projects below for examples of my work.

🌟 Featured Project

A Flask-based REST API for retrieving job postings scraped from Workday-hosted career sites. Supports scalable multi-institution configurations, SQLite database integration, and OpenAPI docs for easy consumption.

  • πŸ” Built for job aggregation and filtering
  • βš™οΈ Modular architecture with clean endpoint structure in JSON format
  • πŸ“„ Auto-generated Swagger documentation
  • πŸ› οΈ SQLite backend

πŸ“Œ Pinned Projects

Here are a few representative projects demonstrating backend integration, automation, data pipelines, and consulting-focused tooling:

  • workday_scraper
    Python script that scrapes job listings from Workday-hosted portals and logs them into Notion databases. Features deduplication, structured logging, and modular scraping logic β€” ideal for API automation and personal job search optimization.
  • news_agg
    News aggregation tool that collects and processes articles from multiple sources (RSS, APIs), with normalization and output formatting. Highlights backend ingestion, scheduling, and extensibility.
  • SQLAlchemy_and_sqlite
    Demonstrates ORM modeling, schema design, and data interaction using SQLAlchemy with SQLite. Emphasizes core RDBMS concepts and programmatic query design β€” aligned with Postgres-focused work.
  • glassdoor_review_analysis
    End-to-end pipeline for scraping, cleaning, and analyzing Glassdoor company reviews. Includes text normalization, sentiment scoring, and reporting β€” a strong example of technical analysis and data transformation.
  • excel-text-differ
    A browser-based tool for comparing columns of text from Excel files using a character-level diff algorithm. Built with SheetJS and Diff Match Patch; demonstrates frontend logic, UX clarity, and integration of third-party libraries.
  • jharemza.github.io
    My personal portfolio site, built with Jekyll and the Chirpy theme. Includes blog posts, project documentation, and technical writing relevant to backend and data workflows.
