About Bon

I am a Senior Python Developer and Data Scientist with 10+ years of experience delivering data-driven solutions across industries such as CPG/FMCG, energy, education, and non-profits. My expertise lies in Python, SQL, Retool, and low-code platforms, with a proven track record of turning complex data into actionable insights and scalable tools.

What I Do

  • Custom Retool Apps & Workflows: I design and build internal tools that transform raw data into decision-ready dashboards. From SQL queries and APIs to dynamic workflows in Python and JavaScript, I help teams work faster and smarter.
  • Data Science & Machine Learning: I’ve led the deployment of predictive algorithms in Python (FastAPI, Pandas, Scikit-learn, TensorFlow) used by hundreds of end-users, including a Pernod Ricard system that boosted brand velocity 2.5x and was featured in a Harvard Business School case study.
  • API & Workflow Integration: I connect ML models to user-facing apps with strong validation, monitoring, and CI/CD practices.
  • Analytics & BI: I deliver interactive dashboards (Power BI, Qlik, Retool) and automated pipelines that empower confident, data-driven decisions.

Highlights

  • Built and scaled a Retool-based decision-support platform for a global sales force (300,000+ outlets).
  • Developed predictive models in production, earning a Global Operational Excellence Award (2025).
  • Supported organizations from Fortune 100s to non-profits, adapting quickly to diverse data environments.
  • Volunteer work as a solutions architect for schools and state organizations, creating impactful community tools.

Tech Stack

  • Programming: Python, JavaScript, SQL, Git
  • Frameworks & Tools: Retool, FastAPI, Streamlit, Jupyter, DBT, Snowflake, Power BI, Qlik
  • Cloud & DevOps: AWS, Azure, CI/CD, Databricks

If you need someone who can bridge data science, automation, and internal tools, while keeping usability and business impact front and center, I’d be glad to help.
