Data science
ML models, computer vision, NLP and analysis that answer the business question — not a model for its own sake.
Scope you can hold us to
Question framing before model work — what decision this answers
ML models you can explain to operators, not only to data teams
Computer vision for images, documents and quality inspection
NLP for classification, extraction, search and support triage
Analysis, dashboards and alerts wired to the decisions they support
Monitoring for drift, freshness and silent failures — plus docs for the next hire
How we deliver data science
- 01Name the decisionThe question, the owner and the cost of being wrong — written first.
- 02Fix the pipesSources, labels and definitions. Models on dirty inputs are theatre.
- 03Model and validateBaselines before cleverness — whether it's tabular ML, vision or NLP.
- 04Put it in the loopAPIs, dashboards or alerts where the decision actually happens.
What that looked like on Plant Disease Classification
- Phase 1
Framed it as a field problem
Detection had to work on a leaf photographed in the field, not a clean lab plate — and it had to justify itself, because an agronomist will not act on a label with no reasoning behind it.
DeliveredScope, dataset and target disease categories
- Phase 2
Transfer learning instead of training from scratch
VGG16 and Inception were combined under transfer learning, so a limited agricultural dataset still reached usable accuracy across disease categories rather than overfitting a small sample.
DeliveredTrained classifier with accuracy reported per category
- Phase 3
Made the model explain itself
Grad-CAM heatmaps expose which regions of the leaf drove each prediction, so a user can see whether the model read the lesion or the background before trusting the result.

Grad-CAM - Phase 4
Shipped inference someone can actually use
A Streamlit app serves real-time predictions on uploaded leaf images — the model reaches the person in the field instead of staying in a notebook.
