👋 Hi, I’m Charles

Investment & Data Analyst based in Nairobi, sitting at the intersection of finance, data, and tooling.

I combine CFA-level finance with Python / SQL / Power BI / Excel modeling to build models and dashboards that decision-makers actually use — from corporate & crypto analytics to forecasting and NLP on company data.

🧩 What I do

  • Financial modeling & valuation

    • Three-statement models, DCF, scenario & sensitivity analysis
    • FAST-style, audit-friendly spreadsheets

  • Business intelligence & reporting

    • Power BI dashboards for sales, risk and operations
    • KPI design, data modeling (DAX), stakeholder-ready layouts

  • Data analysis & forecasting

    • Python (pandas, NumPy, matplotlib, scikit-learn)
    • Time-series forecasting, performance/risk analytics

  • Data prep & feature engineering

    • Cleaning & standardising company/industry datasets
    • Turning text + fundamentals into model-ready features

🛠️ Tools & Stack

Languages & analysis

  • Python · SQL · DAX · Excel / VBA

Data & ML

📂 Selected Projects

A few repos that reflect how I think about finance + data:

  • Power BI Crypto Performance & Risk Dashboard
    Two-page Power BI report for the top 1000 cryptocurrencies, covering market structure, performance heatmaps, volatility, liquidity and tokenomics (supply utilisation & Volume/MarketCap).

  • Blu Containers – Three-Statement Financial Model
    Fully linked three-statement Excel model for a fictitious eco-manufacturing company. Driver-based assumptions, ratios, scenarios and investor-style recommendations.

  • Corporate Finance Model Using FAST
    FAST-standard corporate finance model for a listed Kenyan tobacco manufacturer, with integrated statements, valuation outputs and scenario analysis for equity/credit use cases.

  • Retail Sales Performance & Forecasting
    12-month retail sales case: Pareto analysis, pricing/discount behaviour, time-of-day patterns and baseline time-series forecasting for revenue.

  • Financial Time-Series Forecasting with ML & DL
    Experiments comparing simple baselines vs machine/deep learning models on financial time series, focusing on when extra model complexity actually adds value.

  • Company & Industry Data Pipeline
    End-to-end pipeline to clean, join and feature-engineer company + industry fundamentals as a base layer for research, dashboards and models.

  • NLP on Company Text Data
    Applying NLP techniques to company and industry descriptions to create text-based features for screening, clustering and risk analysis on top of the fundamentals layer.

  • Portfolio Website
    Static site that pulls these projects together and tells the story of how I use finance + data to support real-world decisions.

📌 Outside of GitHub

🔍 What I’m interested in
