I build the unglamorous machinery behind analytics — extraction pipelines, forecasting models and dashboards people actually open. Most recently I automated finance operations at Fintale Consultancy. This September I start the Master of Data Science at the University of Guelph.

AutoDS — autonomous data scientist

A full-stack AutoML application that takes a raw table or a time series and returns a finished analysis: exploratory profiling, preprocessing, model training, diagnostics, explainability, a written report, and an inference endpoint. Built so an analyst can reach a defensible model without hand-writing the same forty notebook cells again.

Canada Labour & Affordability Intelligence

An analytics platform that joins Job Bank, Statistics Canada and CMHC data so you can compare Canadian cities on the things that decide where you move: which occupations are hiring, what they pay, what rent does to that wage, and where the trend is heading. Includes forecasts and automated data-quality checks that flag a source before it quietly breaks a report.

Ask a PDF, get a cited answer

A retrieval-augmented question answering system for documents that runs entirely on your own machine — Ollama embeddings, ChromaDB retrieval, a re-ranking pass to cut weak matches, and Llama 3.2:3b for generation. No document ever leaves the laptop, which is the point.

At Fintale Consultancy

May 2025 — Jul 2026

Fintale builds finance automation software for accounting firms and back offices. I worked as a data analyst across its product line — the extraction pipelines, the Power BI and Python dashboards, and the reporting layers. Three of those products are below, followed by the rest of the portfolio I worked alongside.

Extraction & reconciliation

Extractor.io

Commodity trading back offices receive broker contract notes as PDFs, every broker in a different layout, and someone re-keys thousands of individual fills into Excel to check the bill. Extractor.io detects the format, pulls every fill with its timestamp, runs FIFO matching for realised P&L, values open lots against MCX settlement prices, and rebuilds the day's charges so the broker's own bill can be compared line by line.

Invoicing & collections

InvoiceOS

Accounting firms do the work and then struggle to get paid, because chasing an invoice is awkward and always the lowest-priority task on the desk. InvoiceOS raises GST-compliant invoices, works out the tax split from the client's location, and then chases payment on a timed follow-up ladder that runs from a courtesy nudge to a formal notice. Fintale reports a 32% reduction in 60+ day receivables and 91% of invoices paid before escalation.

Financial intelligence

CFO Intelligence

Accountants spend four to eight hours per client every month rebuilding the same Excel management report. This reads a Trial Balance exported from any accounting package and returns a full dashboard — 20+ KPIs, ratios, cash forecasts, risk alerts — benchmarked against live government-sourced industry data, then exports it as a branded board pack. Fintale puts the turnaround at about a minute per client.

The wider product line

P2P Management

Procure-to-pay with automatic three-way matching; blocks payment when the order, the delivery and the invoice disagree.

Live
AMMS

Reads an incoming business mailbox, OCRs the attachments, classifies each mail and opens a tracked inquiry or tender.

Pre-go-live
Financial Evaluation

Parses Indian MCA company filings, populates a fixed financial model, and produces a reviewed counterparty due-diligence report.

Internal v1
Flow

Practice management for accounting firms — every client job, statutory deadline, review and bill in one register.

In build
Archival Management

Department-wise archival of financial records with an append-only audit trail and no edit or delete path.

Working build
Fintale Lens

Connects to Tally and runs 50+ audit and forensic rules across every voucher, returning severity-ranked findings.

Where I've worked

2024 — 2026

May 2025 — Jul 2026

Fintale Consultancy

Data Analyst, Process Automation · Vadodara

Built the finance team's automation layer: Power BI and Python dashboards, bank-statement extractors, invoice generators, and serverless AWS bots on Lambda, DynamoDB, S3, API Gateway and CloudWatch. Work that used to take an afternoon now finishes while you make coffee — roughly 98% less manual time on the routine workflows.

Jan 2025 — Apr 2025

Inbox Infotech

Data Science Intern · Vadodara

Shipped models against live product problems: a dynamic pricing engine and sentiment analysis for a travel app, customer segmentation for a retail platform to target campaigns properly, and a location-based recommender to lift engagement.

Jul 2024 — Sep 2024

TechXi

Machine Learning Intern · Vadodara

Built "Chat with PDFs" and "Chat with Websites" alongside several other NLP applications, plus audio source separation with Librosa and water-body detection from satellite imagery.

Jun 2024 — Jul 2024

Barodacoders

Frontend Intern · Vadodara

Developed Gyansodho, an education platform where students look up institutes and exam circulars. Focused on the interface and on making it hold up on a phone.
