Skills Summary

Experience

Senior Cloud Developer then Team Lead

Jan 2022 to Jan 2024

Rocket Partners Remote work for Circle K

Altria Project Team lead

• Estanqueros As tech lead I guide and review a remote team (most of the team was in europe!) architecting and documenting the integration, and reviewing code and writing tickets to meet the requirements. The whole project was on a painfully tight schedule. I brought it very close to delivery to prod. This was a data integration project. It integrates with four apis from two eternal sources and four more apis from internal sources. Each integration needed to be separately controllable and troubleshootable and measured for SLO. This enabled the delivery of dynamic promotional content to customers through the injection of highly valuable discounts from several different point of sale scenarios.

Retail Marketing Systems Developer

• Lift This is a system that manages about 20,000 physical endpoints internationally generating over 100 million in annual revenue. It is managed through a custom CMS to configure interactions between the point of sale, shopper, cashier, and system reporting to deliver and account for marketing and activate context relevant upsell opportunities. Prime purpose is the mission critical live handling of loyalty logins and distribution of loyalty benefits.

  I did extensive work maintining this Java 1.6 application. Its deployed on 20,000 hardware and virtual machine hosts across the world. Notably added the first real junit testing procedures and support to a legacy system. Encouraged and helped team to expand test coverage as applicable.

• Lift system websocket/event upgrade proposal Designed and created a proof of concept of managing the Lift systems through a persistent socket connection over RabbitMQ, to enable rapid testing, deployment, updates, and reporting that in the current system can take up to 20 minutes before the system will call home to get instructions. This was never prioritized by the business to proceed, but would have smoothed the lives of all of the operators, programmers, and configurers - basically the entire backend team.

• Lift system runtime upgrade proposal Designed and proofed the upgrade of the 1.6 runtime to 1.8 - this never was prioritized by the business to proceed, but would have greatly smoothed the interaction of the developers with this legacy codebase.

• Lift system tooling and helpers Created tooling to ease the management and access for troubleshooting developers - multiple 6-8 step procedures reduced to single commands. Among them was extraction of configuration structures for local testing, and access to the shell based connection to many end systems for interactive troubleshooting,

• Code quality and versioning advocacy As a legacy codebase, the past practices for versioning and code quality were, honestly disgraceful. Continually improved and advocated for better handling with git, better pipelines, better proof and tests. This is a passion.

• New Data Center Migration Designed and implimented a new global configuration mechanism in the Lift system. Externalizes configuration that was once compiled into the artifacts. Enables quick and smooth transition of any one instance from one configuration to another.

• POS Emulator More work maintining a derivative Java 1.6 application. It is deployed as a development and testing tool on about 100 hardware hosts within the corporate offices, to stand in for actual point of sale systems to activate the desired actions in afformentioned Lift. Engaged in user experience interviews on this application to guide improvements.

• Napper A Java 8 shard-deployed application on amazon ECS providing direct support for field endpoints AND the CMS. This is an abstract capability to provide configured and secured connectivity to our heterogeneous backend data stores. Some modules also serve as middleware to transform data structures. As a core component of the overall system gained a deep understanding to enable reconfiguring, enhancing, and analyzing it.

• CMS Portal An angular app deployed with a support container on amazon ECS. This is a fairly complicated content management system that provides access to a fully user permission controlled system to manipulate the data types that drive the system. There are a large number of people in various roles at the client which interact with this system daily from operational state monitoring of the deployed systems, to the marketing sales staff, to the actual advertisement creation, and on to the quality assurance staff.

• Campaign Planner An embedded capability that uses transforms in Napper, front end programming, and acces sto the back end data sources to provide targeted capabilities that enable the marketing team to create sales proposals driven by actual experienced interactions and traffic in the applications. I helped program middleware components within the Napper.

• Indexer A Java 8 lambda-deployed application on amazon. This is a hard problem - cache invalidation specifically. It exists as a direct consequence of a filter-based approach to configuration in which any change to any data structure requires the reconsideration of all applicable filters to determine if there is a change in state. I have extensively analyzed this function, targeted areas for improvement, and created extensive visual documentation.

• VPN maintenance Leveraged my background in networking to support the VPN implementation, and upskill devops and other engineers on the particulars of this networking related configurations for the server and the related routes among the private networks of aws.

• On-Site Work Although the job is almost entirely telecommute, I have welcomed the opportunity to spend various days onsite with both the client and the team to improve communications through side-conversations and fact-to-face interactions that are always a challenge remotely.

• coordinate converter Coordinate converter is a java application that wraps an official C language library that provides the capability of translating between the various grid and coordinate systems the various military systems use, with an audited and proven level of accuracy. I worked with bridging the C application to the Java application.

• pipeline integration Refined, troubleshooted, upgraded, and maintained both concourse and migration to gitlab-ci pipeline configurations

We implemented scaling policies, extensively used cloudformation templates, interfaced with dynamodb and lambdas. We worked extensively with AWS networking within EC2, gateways, routes, security groups, subnets, vpcs and parameter store. We set up our own openvpn server in each stack to allow connection to the vpc by client. The analysis system used EMR clusters that had their own set of challenges. We worked through a thick compliment of IAM roles and policies that control access to everything. Naturally S3 buckets were used extensively, and we handled dead letter queue matters with SNS and SQS. Mainly, Scripting was accomplished in Python and configuration was in cloudformation templates.
