I turn raw data and rough ideas into things people can actually use — Power BI dashboards, SQL data warehouses, and mobile apps. Currently a Flutter Developer Intern at Client Server Technology Solutions in Hyderabad, with two years of operational data-quality experience at Amazon UK behind me and an MSc in Computing Science from Edinburgh Napier University.

Data + Product mindset Bridging logic & user experience

01 / Story

Data-driven analyst. Hands-on builder.

A data analyst's eye for clean, trustworthy numbers, paired with an engineer's habit of shipping real, working products end to end.

“I collect and clean data, build the model, ship the dashboard — then make sure the numbers actually hold up.”

What I do

Day to day, I own the full analytics workflow — pulling data from multiple sources, cleaning and modelling it, and building interactive Power BI dashboards and SQL warehouses that hold up to scrutiny from business stakeholders. That habit of validating everything came from two years auditing inventory data at Amazon UK.

On the engineering side, I build and ship mobile products in Flutter — currently as an intern at Client Server Technology Solutions, and previously as the lead developer behind a published finance-tracking app used by real shopkeepers and small lenders.

Data & BI

Cleaning and modelling data, then building Power BI dashboards and SQL warehouses stakeholders can trust.

Mobile & web development

Shipping real Flutter and web products end to end — from database schema to production release.

Creating

Videos, web pages, photography and digital art — creative work that sits alongside the engineering.

02 / Experience

Real products, not just tutorials.

From auditing inventory data at Amazon UK to shipping Flutter apps and Power BI dashboards — a track record of owning work end to end.

01 · FLAGSHIP PROJECTFlutter · Dart · Riverpod · Drift/SQLite

Self-Finance

A published, offline-first finance-tracking app for shopkeepers and small lenders — managing customer ledgers, credit entries, repayments and simple-interest loan calculations — taken from concept to Play Store release across 370+ commits. A fully reactive data layer (Drift/SQLite streams + Riverpod) powers custom-painted analytics charts (yearly/monthly/weekly/today), drill-down transaction breakdowns and live KPI cards for outstanding amounts, interest earned and disbursements. It also ships a secure, encrypted local backup/restore system and a PDF invoice generator, keeping all customer data on-device with zero external data collection.

04 / Data & BI

Turning raw tables into decisions.

Power BI dashboards and a full SQL data warehouse — the analytics side of the resume, built with the same rigor as the apps.

01 · DATA PROJECTPower BI · Power Query · DAX

Sales Dashboard 2026 — Power BI

A single-page Power BI report analyzing sales performance by product, category, country and time. Power Query cleans and shapes raw CSV sales data into an orders/customers model; DAX measures cover total sales, order counts and distinct customer counts. Two related tables (orders, customers) are joined on customer_id, with KPI cards for total orders, unique customers and total sales, plus a yearly/quarterly trend line, a product-ranking bar chart, and a category donut chart — all filterable by date range, category and country.

02 · DATA PROJECTSQL Server · T-SQL

SQL Data Warehouse Project

A SQL Server data warehouse built with Medallion Architecture (Bronze/Silver/Gold), integrating ERP and CRM source data delivered as CSVs. ETL pipelines and stored procedures ingest raw data (Bronze), cleanse and standardize it (Silver), and model it into a star schema of fact and dimension tables (Gold) optimized for reporting — with data-quality test scripts validating the Silver and Gold layers, and a documented data catalog and architecture diagrams for stakeholders.

SQL Exploratory Data Analysis

A library of 13+ SQL scripts exploring a relational sales database — database and dimension exploration, date-range checks, measures, magnitude and ranking analysis, time-based trends, cumulative and part-to-whole analysis, and customer/product segmentation, using joins, CTEs, window functions and aggregates to build reusable performance reports.
