The five stages

Turn data into insights and help businesses make better decisions.

  1. Stage 1Months 0–2

    Foundations

    Statistics, SQL and Python are the daily tools — every week you finish a notebook that answers one business-shaped question with data.

    • Python + Pandas + NumPy daily; SQL fluency on a 1M+ row dataset
    • Statistics: hypothesis testing, Bayes basics, regression interpretation
    • Weekly Kaggle / public dataset notebook — clean, comment, publish
    Salary range₹6L – ₹16L
  2. Stage 2Months 2–5

    First job-ready skills

    Each project must end with a measurable business recommendation, not just a chart. Hiring managers cut at this point.

    • Five classical ML projects with feature engineering + cross-validation
    • One causal inference project (matching / diff-in-diff) on a real dataset
    • Build one dashboard (Streamlit / Looker / Metabase) and present it
    Salary range₹6L – ₹16L
  3. Stage 3Months 5–10

    Real projects

    Three case studies a recruiter can scan in 60 seconds: business problem → method → quantified outcome. This is the portfolio that opens product-company interviews.

    • Three end-to-end case studies (data → model → recommendation → impact)
    • Productionise one model: REST endpoint + monitoring + drift checks
    • Lead one A/B experiment from hypothesis to readout
    Salary range₹16L – ₹22L
  4. Stage 4Year 2–3

    Specialisation

    Pick a domain you'll be senior in for the next 4 years. The salary band steepens sharply once you're the go-to person for a function — not a generalist.

    • Domain depth: Growth, Marketing science, Risk/Fraud, Personalisation, or LLMs
    • Causal + experimentation chops: power, MDE, sequential testing
    • Write 6 internal teardowns of model launches — public if possible
    Salary range₹22L – ₹31L
  5. Stage 5Year 4+

    Senior trajectory

    Lead modelling strategy for a product line. Top-quartile Data Scientists at PhonePe / Flipkart / Walmart clear ₹40L+ — but only with measurable revenue impact.

    • Set + defend the model evaluation framework for an entire product area
    • Mentor 2–3 ICs; review their experiment design weekly
    • Influence org strategy: opportunity sizing, what-not-to-build, kill criteria
    Salary range₹31L – ₹45L
