About Me

I am a Computer Science undergraduate who builds at the intersection of data, machine learning, and analytical engineering. My work focuses on transforming raw operational data into decisions-through rigorous exploratory analysis, interpretable predictive models, and dashboards that communicate findings with clarity.

 🎓 Student Performance Prediction — ML Classification Pipeline 

A binary classification system that predicts whether a student will pass or fail before the exam, using behavioural and socioeconomic features. Designed to enable early intervention rather than post-exam remediation — where help can still make a difference.


Attribute Details
Stack Python · Scikit-learn · Pandas · Matplotlib · Seaborn · NumPy
Scale 600 student records · 8 input features · 1 binary classification target
Performance Logistic Regression 94.17% · Random Forest 93.33% · Decision Tree 90.00%
Evaluation Stratified 80/20 split · Confusion Matrix · Classification Report · F1-score
Key Insight Study hours = 44% feature importance (Random Forest) — top actionable predictor
Impact Enables early identification of at-risk students before exam outcomes are fixed
Repository github.com/chinmay2705r/Student-performance-prediction

Feature importance analysis revealed that study hours alone explains 44% of the predictive signal. This is not just a model that works — it is a model that points at something a teacher can act on. That is the difference between an ML experiment and a useful system. Logistic Regression outperformed Random Forest, suggesting the underlying decision boundary is predominantly linear — simpler models win when complexity is not warranted.



 ☕ Coffee Shop Sales Analysis — Business Intelligence Dashboard 

End-to-end business analytics on 149,116 real transactions across 3 NYC coffee shop locations covering January to June. Objective was to identify operational patterns, peak demand windows, and store-level performance differentials to surface actionable management insights.


Attribute Details
Stack Microsoft Excel · Pivot Tables · SUMIF · COUNTIF · AVERAGEIF · Slicers · Charts
Scale 149,116 transactions · 3 store locations · 6 months · $698,812 total revenue
Performance 6-chart interactive dashboard · Sub-second slicer response · 7 business questions
Evaluation KPI cards · Month/day slicers · Category and product-level breakdown
Key Insight 9–10 AM peak demand window · Hell's Kitchen leads at $236,511 · Barista Espresso top product
Impact Staffing, inventory, and marketing decisions directly derivable from dashboard output
Repository github.com/chinmay2705r/coffee-shop-sales-analysis

Peak revenue at 9–10 AM across all 3 locations is directly actionable for staffing rotations. Hell's Kitchen outperforms comparable stores not in footfall but in average transaction value — a signal worth investigating for replication. The dashboard answers 7 distinct business questions without any additional analysis required.



 📊 Retail Sales EDA Dashboard — Python Analytics System 

Exploratory data analysis on 500+ retail orders across 5 product categories and 4 Indian metro regions. Core objective was identifying the source of profit leakage and building a visual system that communicates findings clearly enough to drive a policy recommendation.


Attribute Details
Stack Python · Pandas · Matplotlib · Seaborn · NumPy
Scale 500+ orders · 5 product categories · 4 metro regions · 12 months
Performance 6-chart dashboard — bar · line · pie · boxplot · scatter · KPI panel
Evaluation Correlation matrix · Distribution analysis · Outlier detection · Profit margin tracking
Key Insight 38% of orders with discounts above 30% were directly loss-making
Impact 25% discount cap recommendation projected to reduce loss-making orders by 17%
Repository github.com/chinmay2705r/sales-data-analysis

A scatter plot of sales versus profit, coloured by discount level, revealed a clear loss cluster at high discount values. The correlation was strong enough to justify a direct policy recommendation. This is the kind of output that has business value — not just a model, but a finding that can be acted on in a meeting.
