Hi, I’mSwati Tiwari
Data Scientist & Analyst|Python · SQL · ML · Power BI
PG Diploma in Data Science & AI with 6+ years of operations experience analysing CRM data and tracking KPIs. I build supervised learning and forecasting models, deploy them as live apps, and present results in Power BI so business teams can act on them.
Tools I work with
PythonLive ML appsPower BISix years of owning KPIs on the floor taught me what a number is worth. Now I build the models behind those numbers.
I know what a business number means because I used to be accountable for it.
About me
From KPIs on the floor to models in production
Six-plus years in operations, including three-plus as a team leader analysing CRM data. BCA graduate with a PG Diploma in Data Science & AI, now building supervised, tree-based and time-series models.
My strength is explaining results to non-technical stakeholders, a habit built by reporting to senior management through MIS reports. I’m looking for a role where I own the workflow from cleaning to deployment.
Experience
Where I’ve worked
Data Scientist Apprentice · Spinnaker Analytics (Remote)
- Build end-to-end ML workflows in Python: data cleaning, EDA, missing-value imputation, feature engineering, and model training and evaluation.
- Develop and compare classification, regression and time-series forecasting models (Random Forest, XGBoost, Gradient Boosting, SARIMA, Holt-Winters), tuned with GridSearchCV, randomized search and cross-validation.
- Build reusable Scikit-Learn preprocessing pipelines and explain model predictions with feature and permutation importance.
- Deploy a model as a Streamlit app and present results in interactive dashboards (Power BI and HTML) for business teams.
Team Leader, Operations · Hansa Direct, Quess Corp, Digitide Solutions
- Analysed large CRM datasets to find productivity gaps and prepared MIS reports for senior management.
- Set and tracked SLAs, conversion and cost-per-lead targets for a team of up to 15 members.
- Used performance data to plan coaching and training, which improved team conversion metrics.
Operations Executive · Hansa Direct
- Handled the Twitter and email support channels for the Mahindra Automotives account, resolving customer queries and complaints.
