Quick, what is this diagram trying to show? I hope you know your AWS icons. There’s over 200 services and I have to guess frequently when playing the AWS Logo Quiz. While this diagram could easily add some descriptive labels to help, the icons assume developers can remember what the icon means. Some color-blind people … Continue reading "Technical Diagrams – Stop using cloud logos"
I’ve previously explored the world of home energy monitoring systems and in the past arrived at using the Brultech GreenEye Monitor for a project in a friend’s house. It had the advantage of being local out-of-the-box and had a wide range of compact CTs that made fitting the electronics in the breaker box a lot … Continue reading "Local Energy Monitoring using the Emporia Vue 2"
I upgraded to Apache Zeppelin v0.10.x from v0.9.x and randomly my Python Matplotlib scripts stopped rendering images. Anything that called the plot method would just return the string response of the function. Like below: If this happens to you, just add the following directive after %python: After that, it should work again: I’m not sure … Continue reading "Zeppelin v0.10 not showing matplotlib graphs"
I was responsible for building a domain-specific authorization system that 20+ different services leveraged to secure the AWS hardware and Amazon Devices supply chain
Senior Software Engineer
Amazon.com, Inc.
Physical Stores Tech
Upon joining, I rapidly identified fundamental problems in the system and came up with a multi-phased plan to enable the Amazon Fresh store launch to unblock and launch (this was visible at the VP level) and longer-term projects to improve scaling and stability.
I set a long-term technical vision for a project spanning two teams and oversaw tech designs from other engineers to fit within that vision.
I worked with the product team to develop a product vision for a new internal template development editor that is expected to have a separate development team and product team.
Senior Software Engineer
Amazon.com, Inc.
Normalization Learning Systems
I worked to improve team productivity and robustness of changes by introducing design reviews/templates and improve team code quality output with standards.
I analyzed an existing team's processes and technical bar to identify weaknesses in team culture and engineering excellence and came up with multiple short-term and long-term plans to reduce technical debt.
Senior Software Engineer
Amazon.com, Inc.
Softlines Selection Systems
I improved developer productivity by recognizing gaps in Amazon’s existing alarming and service management and designed solutions using AWS X-Ray and open-source exception tracking tools. I am actively working to drive adoption from other teams and departments.
Software Engineer II
Amazon.com, Inc.
Softlines Selection Systems
I led high-impact projects with VP-level visibility from the requirements phase through to production. These projects required coordinating changes across multiple engineers and different teams requiring leadership and influencing skills.
I developed new business goals by identifying opportunities to improve productivity and increase revenue. I wrote business documents that were reviewed by senior stakeholders and developed these into technical project designs.
I consistently drove higher standards in code quality, architecture designs, and feature UX across multiple teams through design reviews, quality improvement campaigns, and code reviews.
Software Development Engineer
Amazon.com, Inc.
Softlines Selection Systems
I joined a brand new team that enabled Amazon to effectively plan selection of clothing/fashion products. I owned and drove code quality/infrastructure standards across the entire system (front-end three-tier and a back-end Apache Spark pipeline) using code analysis and code reviews.
I oversaw the design and implementation of an interactive OLAP-style analytics/deep-dive UI and service that implemented a custom query execution engine to interact with Elasticsearch. Queries were optimized to aggregate and search across billions of products in the Amazon catalog.
I directly worked with stakeholders to understand feature requirements and translated those into actionable technical implementation projects.
I contributed multiple changes to core Amazon frameworks, including a service communication framework widely used by teams across Amazon.
