I help growing companies turn messy operational data into reliable, analytics-ready infrastructure — and turn that data into insights teams actually use to make decisions. Over 5+ years, I've worked across the full data lifecycle for a logistics/SaaS company: building production pipelines, modeling data warehouses, optimizing databases, and delivering the reporting and analysis that came out the other end. Data Engineering Production ETL/ELT pipelines (batch and real-time/CDC) Data warehouse design & modeling (star/snowflake schema, SCD) Database optimization — query tuning, indexing, materialized views Orchestration (Airflow) and transformation (dbt) Automating manual/Excel-based reporting workflows Data Analysis & BI Exploratory analysis and ad hoc SQL reporting KPI frameworks and business metrics design Dashboard build-outs (Power BI, Apache Superset) Data cleaning, validation, and reconciliation Translating raw data into decisions — not just charts Tools I work in: Python, SQL, PostgreSQL, MySQL/MariaDB, MongoDB, BigQuery, ClickHouse, Databricks, PySpark, Apache Airflow, Apache NiFi, Debezium (CDC), dbt, Kafka, Power BI, Apache Superset. Where I add the most value: companies (10–500 employees) in SaaS, logistics, e-commerce, or fintech — whether you need someone to build the pipeline from scratch, fix a database that's buckling under real usage, or just make sense of the data you already have. Comfortable owning a project end-to-end, or plugging into a specific piece (a query, a dashboard, a pipeline fix) — happy to scope to what you actually need. Let's talk about what's slowing your data down.

Rohan S. has worked .
Data Scientist & AI/ML Engineer with 5+ years in building systems that think, predict, and automate; not just API calls. I take raw, messy and unstructured data and turn it into production-ready pipelines, predictive models, and executive dashboards that drive decisions. I design and ship end-to-end data and ML systems: reducing time-to-insight from weeks to hours, automating workflows that used to take entire teams, and building models that directly feed revenue. If your business runs on data, I make it generate revenue, not just reports. 🔧 Core Expertise 1. Data Analytics & BI : Exploratory analysis, KPI frameworks, executive dashboards, A/B testing, cohort analysis (Excel, Power BI, Tableau, Plotly, Looker) 2. Data Science & ML : Predictive modeling, forecasting, statistical analysis, feature engineering, model validation and deployment (Scikit-Learn, PyTorch, TensorFlow, MLflow, AWS SageMaker) 3. Data Engineering : End-to-End pipelines, ETL/ELT automation, data warehousing, real-time and batch processing (Snowflake, Databricks, dbt, Apache Spark, Airflow) 4. Generative AI : RAG pipelines, LLM fine-tuning, agentic workflows, semantic search, prompt engineering, vector databases (LangChain, LlamaIndex, Pinecone, FAISS, OpenAI, HuggingFace) 5. Automation : Workflow orchestration, API integrations, intelligent agents, process automation, web scraping (n8n, Airflow, Lambda, Selenium, BeautifulSoup) 6. Cloud & Infrastructure model deployment, scalable data systems, serverless pipelines, storage and compute (AWS- SageMaker, EC2, S3, Lambda, RDS) 💡Why Clients Work With Me Most data projects fail not because of bad data, but because the person handling it understands models but not business. I bridge both. 5+ years solving real business problems with AI and data means I understand the business problem before I touch the data, and I build solutions that solve it end to end. I communicate at every step, flag issues before they become problems, and make sure what I build fits your workflow, your team, and your timeline. What you get is senior expertise, fast turnaround, and work that is built to last beyond the contract. Let's Talk If you have data that is not working hard enough for your business, that is exactly the problem I solve. Send me a message describing your project, and I will respond within an hour.
