Hi, I'm Ahmed Balde

I build practical software, data, GIS, and test-automation projects with a focus on application support, quality engineering, backend/API development, and reproducible delivery. I am pursuing opportunities in Application Support, QA Automation, Software Testing, Junior Software Engineering, GIS/Data Engineering, and entry-level Data or AI Engineering.

Core focus

  • GIS & Spatial Data — building the Indy Geospatial Accessibility Platform with PostGIS, GeoPandas, and MapLibre.
  • Backend/API Development — designing FastAPI and Spring Boot services backed by PostgreSQL.
  • Data Engineering — creating reproducible pipelines, validation workflows, and audit reporting.
  • SQL — using relational data modeling, querying, and troubleshooting across analytics and application projects.

Top 6 projects

These projects match the repositories currently pinned on my GitHub profile.

  1. Indy Geospatial Accessibility Platform — PostGIS, FastAPI, React, and MapLibre platform for transparent Marion County transit and essential-service accessibility indicators.
  2. Cloud Data Engineering Platform — Reproducible e-commerce event pipeline with Python contracts, Kafka, PostgreSQL, Airflow, dbt, FastAPI, and a React dashboard.
  3. Loyalty Analytics Agent — FastAPI loyalty analytics platform with a secure dashboard and constrained AI analyst.
  4. Java Application Support Lab — Spring Boot support-ticket application demonstrating SQL troubleshooting, MVC testing, validation, and maintainable CI.
  5. Automated Regression Testing Suite — TypeScript and Playwright framework with Page Objects, fixtures, CI, HTML reports, and failure evidence.
  6. Document Intelligence Platform — Full-stack OCR, document review, vector search, and citation-grounded Q&A workspace using FastAPI, React, PostgreSQL, and Docker.

What these projects demonstrate

  • Building GIS and spatial-data workflows that turn public data into transparent, documented indicators.
  • Designing maintainable backend and API services with FastAPI, Spring Boot, PostgreSQL, and SQL.
  • Creating reproducible data pipelines with validation, audit reporting, and clear data-quality limitations.
  • Applying analytics methods such as segmentation, matched-control experimentation, and uplift analysis.
  • Developing AI-enabled document and analytics workflows with traceable outputs and explicit boundaries.
  • Designing automated browser coverage, meaningful test evidence, and repeatable CI delivery practices.

Collaborative coursework

I have also contributed to team repositories involving Python/FastAPI integration, C# API work, and shared GitHub pull-request workflows.
