Leader Spotlight: Zooming out and widening your aperture, with Vaarrun Bimbhat

Vaarrun Bimbhat, former Head of Product at Shopify, discusses the importance of zooming out to see the big picture and evaluate a product portfolio to balance risk and innovation.
When it comes to shifting focus from short-term goals to long-term growth, it depends on the context, as some growth teams focused on executing multiple experiments to achieve short term results do not need to pivot their focus.
To identify problems that are overlooked and have potential to drive significant value, Vaarrun suggests looking at what competitors are doing, partnering with advocates and customers, and examining developments in other geographies.
Vaarrun recommends designing and executing iterative tests to quickly get to the local maximum and to identify the global optimum, and to build a balanced product portfolio that effectively serves the company's long-term goals.
To discover leading indicators of diminishing returns, Vaarrun recommends looking out for customer support tickets and tracking user satisfaction or revenue metrics.
It's important to prioritize problem discovery and proceed with an open mind so that customer needs can be uncovered continuously, and to pivot quickly when making decisions to maximize outcomes.
Vaarrun uses methods like pre-mortems, probing customer questions, and analyzing data with other teams to investigate patterns and identify risks. He emphasizes the need to widen one’s aperture to get stronger synthesis when evaluating the entire problem space.
Vaarrun encourages his teams to zoom out, avoid confirmation bias, and to think about leading indicators of emerging trends, both in terms of the problem space and the customer landscape overall.
Vaarrun's interview provides insights into how prioritizing a global optimum versus a local maximum, and a balanced product portfolio, can drive innovation and sustainable long-term growth.
Vaarrun’s focus on product management strategies that help teams pivot quickly and widen their aperture empirically is a great lesson for product managers at all levels.

Automating Limit Orders on Polygon with TypeScript, 0x, and Terraform

This article is about building a TypeScript service for executing limit orders on Polygon using the 0x Swap API and Terraform.
To keep transaction costs low, this article uses Polygon, an Ethereum Layer 2 solution and focuses on trading two assets: wrapped Ethereum (WETH) and USDC.
The article shows how to store limit orders in a DynamoDB table and access environment variables through getEnvVar utility.
The article demonstrates how to create a Telegram bot for receiving notifications when executing swaps. To enhance security, it also shows how to store sensitive information like Telegram bot token in AWS Secrets Manager.
CoinGecko API is used for fetching cryptocurrency prices. The article shows how to generate a private key, withdraw assets, and handle asset balances during withdrawal.
The article explains how to execute swap using the 0x Swap API and EIP-712 signatures. It also explains how to set allowance, prepare and send transactions, and verify transaction success.
The core function for executing limit orders is demonstrated by fetching the current prices of assets, evaluating each order's condition and executing swaps using 0x Swap API. AWS Lambda and Sentry are used for deploying and monitoring service respectively.
Finally, Terraform is used to provision the necessary AWS resources for the service and the article concludes by stating that this system is ready to handle trades reliably and efficiently, with robust notifications, secure secrets management, and automated scheduling.

System Analysis and Design: Program Sales & Inventory Management Toko PUSAKA MOTOR

The Sales and Inventory Management Program was designed to help Pusaka Motor simplify their daily transaction recordings and ease inventory management. It has an optimized desktop interface that streamlines their inventory and improves data management. Four members were assigned to this project; Felicia acted as the Project Manager, Valentyno acted as the System Analyst, Sharon acted as the System Designer, and Bernard was the programmer. The program has three user roles: Owner, Cashier, and Inventory. The activities involved in the system revolve around the purchase process, which begins with the customer placing an order. There are 69 pages in the article summarizing the activities involved in this project.
Testing of the program using the Black-Box Testing technique was conducted with the owner, cashier, and inventory employee. After completing all the tasks, users are asked one question about their satisfaction level with the overall program, and the results show that they are satisfied with the program they have tested.
The program comes with numerous features such as the owner’s dashboard, item view, insert item, employee list, add employee, edit employee, supplier list, sales list, sales detail, insert sales, sales invoice, receivable payment, purchase list, insert purchase, purchase detail view, payable debt payment, stock opname list, insert stock opname, stock report view, sales report view, purchase report view, and settings view for owner, cashier, and inventory employee.
Each user can only access what they need to carry out their tasks effectively. The owner has full access to all the program’s features, whereas the cashier has limited access, and the inventory employee can view, add, edit and delete products.
The testing method chosen includes qualitative interviews with users following the provided test cases and quantitative measurements using Single Ease Question (SEQ) and Customer Satisfaction (CSAT) ratings. All features of the program were tested with the owner, cashier, and inventory employee.
Based on the testing, the program operates as expected functionally, and users rated it easy to understand in terms of workflow, scoring an average of 6.757 out of 7. User satisfaction was rated at 8.67 out of 10.
Overall, the Sales and Inventory Management Program streamlines and simplifies the inventory management process for PUSAKA MOTOR, helping them manage data efficiently. It has an easy-to-use interface and tailored user roles, making it easy for users to access and use effectively.
The project also included steps such as fact-finding, process modeling, and architecture. A Level 0 Data Flow Diagram and Context Diagram were also provided to understand the program's overall performance.
The program has a user access control feature that allows multiple users, and it has been designed to help the store owner in performing essential tasks such as recording sales, monitoring inventory, and preparing company reports.
Since its inception in 1980, inventory management has been a significant challenge in PUSAKA MOTOR. The new desktop application, designed by a team of students from Ciputra University, solves this challenge and provides a clear and accurate overview of their business performance.
The application has been designed to handle a wide range of automotive spare parts, and to make the inventory and sales processes more efficient and manageable.
