Ahmed Balde

Software engineer and data-focused developer building practical systems across application support, quality engineering, geospatial analysis, AI/ML, and cybersecurity.

I focus on projects that are reproducible, documented, tested, and grounded in a real operational problem.

Featured engineering projects

Full-stack PostGIS, FastAPI, React, and MapLibre application measuring public-transit and essential-service accessibility across Marion County, Indiana. Includes reproducible spatial analysis, API tests, responsive maps, architecture documentation, and verified desktop/mobile screenshots.

FastAPI and React document-processing workspace using PostgreSQL, Docker, OCR, and structured extraction to turn uploaded documents into searchable information.

Cloud-oriented e-commerce data platform with event ingestion, analytics pipelines, APIs, dashboards, containerized local development, and AWS infrastructure.

Production-style FastAPI analytics application with a secure dashboard, constrained AI assistance, validation, and deployment documentation.

Quality engineering and application support

  • Automated Regression Testing Suite — Playwright and TypeScript framework with traceable browser scenarios, Page Objects, CI, HTML/Allure reporting, screenshots, video, and failure traces.
  • Java Application Support Lab — Spring Boot support application demonstrating Java upgrades, SQL troubleshooting, regression testing, validation, and CI.
  • Workforce Data Audit Tool — Installable Python and SQL data-validation tool with risk analysis, audit reporting, tests, and documentation.

Team contributions

Integration contributor on a Python system evaluating AI models, datasets, and repositories. I opened PR #17 to bring the frontend/backend integration branch together for review. Teammates owned the core evaluation engine, handlers, metrics, and deployment components.

API contributor working through ticket-based branches. My merged PR #14 updated the C# weather endpoint and synchronized the feature branch with the shared default branch.

Early-stage workflow contribution through a personal feature branch and merged PR #5. This contribution focused on repository workflow rather than a production feature.

What I bring

  • Evidence-driven troubleshooting across application, API, database, and browser layers
  • Automated testing with useful failure diagnostics
  • Reproducible data and geospatial analysis
  • Clear technical documentation, setup instructions, and limitations
  • Responsible handling of security, forensic, and team-project material

Every featured repository links directly to source code, setup instructions, verification evidence, or a clearly labeled case-study methodology.
