Stephen Baraik
I build reliable data infrastructure and machine learning systems that turn raw data into products people actually use.
I'm a data professional based in Navi Mumbai, India, working across ETL pipelines, machine learning, and AI application development. My focus is on building things that hold up in production, not just in a notebook.
01 — About
About Me
I'm a Data Management Analyst at Zoc Learnings, where I work at the intersection of data engineering and applied AI — building CRM data pipelines, automating reporting, and prototyping RAG-based tools for the business. I graduated from NMIMS University with a B.Sc. in Data Science in 2026, and I hold a DataCamp Associate Data Engineer certification.
Outside my day job, I build end-to-end products: forecasting engines, dashboard frameworks, real-time data pipelines, and full-stack applications. I care about the unglamorous parts of data work — clean pipelines, honest model evaluation, and systems that don't fall over.
Alongside my day job, I run Elnova AI, an AI consulting practice helping businesses adopt AI in practical, high-ROI ways, and I take on freelance projects building websites for small and medium businesses.
I'm currently exploring opportunities based in Singapore, and I'm always open to conversations about data engineering, machine learning, and building useful products.

Ventures & Freelance Work
Elnova AI — Founder
AI Consulting & AgencyElnova AI is an AI consulting practice I run alongside my full-time work, helping businesses figure out where AI actually fits into their operations and then building it for them — from automation and internal tooling to custom LLM-powered applications.
- Advise SMBs and founders on practical, high-ROI AI adoption: automation, chatbots, internal copilots, and data workflows, rather than AI for its own sake.
- Design and build custom AI solutions end-to-end: scoping, model/tool selection, prototyping, and production deployment.
- Bring the same production-grade engineering standards from my data science work — clean pipelines, monitored systems, and honest evaluation — into client projects.
Freelance Web Development — SMB Websites
Alongside Elnova AI, I take on freelance projects building websites for small and medium businesses that need a clean, functional web presence without enterprise-agency overhead.
- Design and build fast, modern websites for SMBs — landing pages, business sites, and small e-commerce — end to end.
- Handle the full stack: design, frontend build, deployment, and basic SEO/schema setup.
- Focus on quick turnaround and direct communication, since most clients are small teams who need things shipped, not managed.

Featured Projects
Stormwatch AI — Extreme Weather Prediction System
Trained ML models forecasting cyclones (98%), heatwaves (99%), and rainfall (88%) across 15 Indian cities on 90,000+ real records.
- Identified and fixed label leakage across 3 models, correcting an inflated 99.7% rainfall accuracy down to a genuine, trustworthy 88.3%.
- Deployed a 5-endpoint FastAPI service with an MLflow registry and Docker Compose, processing 90k+ records through a PySpark ETL pipeline.
- Automated CI/CD with GitHub Actions, backed by 80 passing pytest tests and KS-test drift monitoring.
PaisaPro — AI Investment Advisory Platform
An AI-powered forecasting and risk engine covering 502 NSE/BSE stocks, combining classical quant models with an LLM-driven advisor.
- Built forecasting and risk models using ARIMA, GARCH(1,1), and the Fama-French 4-factor model.
- Trained a walk-forward-validated ML ensemble on 20+ OHLCV features for 30-day price prediction.
- Built a FastAPI backend with 35+ endpoints across 19 services, powering an agentic Llama 3.3 advisor with live tool calls over SSE.
- Shipped an 18-page React SPA on Netlify, backed by Supabase and a Hugging Face Spaces Docker deployment.
ChartCraft — Open-Source Python Dashboard Framework
An open-source Python dashboard library built to rival Power BI and Tableau, with 18+ chart types and 11 themes.
- Engineered the core on Python's standard library and Apache ECharts 5.5, with zero external dependencies.
- Built a drag-and-drop canvas synced with the underlying Python in real time via bidirectional, AST-based codegen.
- Shipped SSE-based live streaming with independent per-chart refresh, plus export to HTML, Jupyter, Docker, and PDF.
Bitcoin Data Pipeline
A fully containerized real-time and historical data pipeline for Bitcoin market data.
- Automated a Python module pulling historical and real-time OHLC candles from the Binance API.
- Built two Airflow DAGs: one for historical backfill, one for real-time ingestion running every minute.
- Persisted candle data in PostgreSQL with idempotent inserts to prevent duplicate records.
- Containerized the full stack (Airflow, PostgreSQL, pgAdmin) with Docker Compose for reproducible local setup.
