Cover image for 🛠️ DevOps Tips 🛠️ If
🛠️ DevOps Tips 🛠️ If your GitHub workflows or jobs are failing due to jobs concurrently accessing and/or modifying shared resources, You can control execution at the workflow or job levels using the concurrency. Jobs/Workflows in the same are prohibited from running at the same time, and you can cancel any jobs/workflow if you trigger another one. Groups let you define compartments in which you don't want concurrent workflows running. They can be organized however you like. I find that using them in separate environments is a great practice. Cancel-in-progress: specifies if the old running job/workflow needs to shut down.

One of the most common problems I see as companies grow isn’t a lack of data — it’s too many disconnected reports. In this project, leadership relied on spreadsheets and ad hoc reports. Numbers didn’t always line up, and answering basic questions took too long. What I did: Centralized reporting in Power BI Defined clear, decision-driven KPIs Modeled data so metrics reconciled across teams Designed dashboards focused on clarity The result: Leadership gained a trusted, real-time view of performance they could rely on week after week.

Financial dashboards shouldn’t just show trends — they should explain what’s driving profitability. In this project, I built a Tableau dashboard that connects weekly sales, costs, profit, and ROI in a single view, allowing leaders to see where and when returns were actually being generated. What I focused on: Aligning sales, cost, and profit to the same time grain Making ROI visible alongside volume, not buried in spreadsheets Enabling quick comparisons across venues, vendors, and performers The result: Teams could identify high-ROI weeks and segments and make informed decisions about pricing, spend, and future bookings.

Adding a new company into an existing reporting suite this week as our client continues to grow. The work isn’t just wiring in new data — it’s making sure metrics stay consistent, historical trends remain intact, and leadership can still compare performance across the business without friction. Growth is exciting, but it definitely stress-tests your analytics.

Cover image for Problem: Many organizations still process invoices
Problem: Many organizations still process invoices manually by reading PDF documents and entering key details (invoice number, vendor, amount, etc.) into systems. This process is slow, error-prone, and difficult to scale, and it also makes it harder to detect duplicate invoices or incorrect totals. Solution: This project builds an automated invoice processing pipeline that converts uploaded invoice PDFs into structured data. It uses OCR to extract text, LLMs to identify invoice fields, validation checks to ensure correctness, and Kafka-based event streaming to manage the processing pipeline. The extracted data is stored in PostgreSQL and visualized through a dashboard, enabling faster, scalable, and more reliable invoice processing.

Problem Statement Urban traffic management systems lack real-time, integrated data combining traffic conditions with weather patterns. This results in poor routing decisions, delayed emergency responses, and inefficient traffic flow management. Solution Developed a comprehensive real-time ETL pipeline that integrates traffic APIs and weather data sources, processes millions of data points, and delivers actionable insights through interactive dashboards for traffic management and route optimization.
