Data Science Intern
May 2025 – Aug 2025
Worked on medical imaging ML for automated blood cell classification using transfer learning and CNNs to support faster, more accurate microscopic analysis.
Tech Stack: Python, TensorFlow, Keras, NumPy, Pandas, Scikit-learn, Jupyter, Git, Kaggle
- Fine-tuned pre-trained convolutional neural network architectures using TensorFlow and Keras on a 12,500-image Kaggle blood cell dataset, achieving 95% classification accuracy and outperforming a baseline CNN trained from scratch.
- Implemented an image preprocessing and augmentation pipeline (normalization, rotations, flips, scaling) in Python and NumPy to increase dataset diversity and improve model generalization.
- Performed hyperparameter tuning (learning rate schedules, batch size, early stopping) and training optimizations to accelerate convergence and reduce overall training time across experiments.
- Conducted model evaluation and error analysis using confusion matrices and per-class precision/recall to identify under-performing classes and guide targeted augmentation strategies.
- Packaged the trained inference pipeline in reproducible Jupyter notebooks and version-controlled code (Git), delivering a faster, more accurate alternative to manual microscopic review and reducing analyst workload.
- Documented experiments, tracked model artifacts and results to enable reproducibility and handover to cross-functional stakeholders for potential integration into clinical workflows.
Projects
HematoVision: Advanced Blood Cell Classification Using Transfer Learning | 2025 – 2025
Tools Used: Python, TensorFlow, Keras, NumPy, Pandas, Data Augmentation
- Designed and implemented an end-to-end image classification pipeline using transfer learning with pre-trained CNNs (TensorFlow/Keras) to classify microscopic blood cell images from blood smear data.
- Achieved higher classification accuracy and faster training convergence compared to a baseline CNN trained from scratch by applying transfer learning, preprocessing, and augmentation techniques and validating on a held-out set.
- Prepared reusable code, model checkpoints, and inference notebooks to demonstrate scalability and support potential integration into healthcare analysis workflows.

- Drivetube Profile — your free digital resume — at drivetube.ai/in/your-name: one true standard resume with a Hiring Snapshot (visa status, expected salary, notice period, work preference, relocation), an ATS-ready PDF download and a single shareable link. Free forever; interview requests come from verified employers and your contact details stay masked until you accept. Documentation.
- Free Job Board — verified openings crawled ATS-by-ATS from 100,000+ real company career pages across 35 ATS platforms. Shows the true posting date from the source ATS — not when a listing was indexed — and deletes every general listing 3 days after it was actually posted. No ghost jobs, no ad-sponsored listings, no staffing reposts, no account needed. Documentation.
- Job Hunt Program — managed job hunting, a one-time purchase from $199.99. JobScout matches verified roles to your real experience band, Blend AI writes a uniquely tailored resume and cover letter for every application, and the Autofill extension fills the form — or Let Us Apply submits it for you. Documentation.
- Resume Writing Services — human-written, ATS-optimised resumes by senior career writers, from ₹499.99 / $25.99. Available in every country, written to the destination country's own standard — a US resume, UK CV, German Lebenslauf and Indian resume are genuinely different documents. A paid service, separate from the free Drivetube Profile. Documentation.
- Community Membership — from $4.99/month (₹1,999/year in India). Unlocks the gated job-board filters — visa sponsorship, security clearance, workplace and application time — plus Job-Scout AI matching, Resume Report AI, Interview AI prep sheets, Recruiter Outreach AI sent from your own Gmail, Apply or Skip triage, a daily market feed and a $10,000+ library including 23 ATS-validated resume templates. Documentation.
- Drivetube Hire — for employers — hiring with no job postings and no applications. Paste your real job description and AI matches it against candidates' true standard resumes, returning ranked candidates with a match %, matched and missing skills and written reasoning. Free tier included; employers pay, candidates never do. Documentation.
Full product documentation — every product explained, with feature-by-feature comparisons against the job boards, AI apply tools, resume services and hiring platforms people actually use.
