# Adam Dziuk > Staff Software Engineer at Uber Location: San Francisco Bay Area, United States Profile: https://flows.cv/adamdziuk I am a pre-med student turned software engineer with a boundless passion for all things technology. Bioinformatics research introduced me to software and I haven't stopped coding since. I'm always looking for a difficult problem to solve and I'm always eager to learn a new technology to add to my toolset. Experienced across the entire software stack with a focus in backend engineering, designing and building scalable, reliable, and resilient system architectures. ## Work Experience ### Staff Software Engineer @ Uber Jan 2022 – Present | San Francisco Bay Area ### Senior Software Engineer @ Uber Jan 2021 – Jan 2022 | San Francisco Bay Area • Senior Backend Engineer on Consumer Experience team (Rider Org) • Our team owns the effort to consolidate all Uber products as a unified SuperApp experience in the Rider App as well as in-app messaging • Inherited the Consumer Messaging product in January 2021. Led efforts to identify performance and reliability issues and coordinate and delegate projects within the team to address what was discovered • H1'21 performance wins resulted in cutting product p99 latency in half by migrating to better suited downstream services and datastores with further improvements currently in-flight • H1'21 reliability wins resulted in a month-over-month reduction of engineering alerts from ~60/month to ~20/month • Led and delivered effort to supplement the existing event-based message campaign model with real-time targeting capabilities • Currently leading a team-wide effort to establish a long-term (18 months+) engineering vision/framework. This will serve as a north star to drive better-informed engineering decisions for all of the team's projects • One of two leads of the Rider Incident Committee. Responsibilities include coordinating and leading reviews of postmortems for all major Rider outages, planning follow-up tasks, and driving initiatives through the committee to improve org-wide reliability • One of the backend specialists for the Rider Org's ERD committee, serving as one of the primary backend reviewers of all proposed Rider projects • Owner of Rider Org Testing OKRs; tasked with defining and monitoring progress of org-wide OKRs (eg. integration testing, unit testing) • Mentor for multiple backend engineers across the org and on the interview team Currently Using: Golang, Java, Kafka, Redis, Cassandra, MySQL, gRPC, and Uber proprietary datastores and technologies ### Senior Software Engineer @ Uber Jan 2020 – Jan 2021 | San Francisco, California, United States • Tech lead of Emobility Core, a team tasked with designing and building the foundational backend architecture for the entire JUMP product • Proposed and led a project for moving vehicle communications from acquired JUMP MQTT stack to Uber's gRPC infrastructure • Lead author of proposal for defining the post-migration architecture. The proposal consisted of iterative milestones for building towards a streamlined architecture that removed code duplication and reconciled service and feature ownership all while delivering new feature asks in the process. Project was approved and resourced, including delivering the first milestone (vehicle communications domain), before JUMP was acquired by Lime • Served as main point of contact for the Lime engineering team for migrating infra & vehicle communications Used: Golang, Java, Uber Cadence, Kafka, Redis, Cassandra, MySQL, gRPC, MQTT, AMQP, RabbitMQ, AWS, and other Uber proprietary datastores and technologies ### Software Engineer II @ Uber Jan 2019 – Jan 2020 | San Francisco Bay Area • One of the lead engineers for architecting and implementing Uber's rewrite of the acquired JUMP backend. Focused on integrations with Uber platform services, vehicle communications, vehicle state & data, and rental flow. • Proposed and led the creation of backend engineering standards for the NeMo Micromobility organization. Established patterns, such as workflow state machines (using Uber Cadence), that were used by multiple teams across the org. • Primary engineer for building out and maintaining the AWS environment that Uber JUMP backend relies on. • Led a project to re-architect how Uber backend processes vehicle communications. Sole author of the proposal and led a small team in its successful implementation and migration. Resulted in higher resilience in preventing message loss, ability to replay any sequence of vehicle messages, automatic ETL of all vehicle communications for data engineering and data science projects, and the ability for any external Uber team or org to consume/process communications in real-time seamlessly. • Promoted after 12 months of joining. ### Senior Software Engineer @ SafeGraph Jan 2017 – Jan 2018 | San Francisco Bay Area • Wrote Spark jobs that process terabytes of data daily. Areas of focus included ingesting and enhancing movement data and building maps using point-of-interest and polygon data. • Architected and built out the majority of the first customer-facing UI, including the front-end in Vue.js and API in Play Framework. • Designed and built an API with Akka for ingesting payloads from mobile SDKs. • Upon joining, refactored Spark jobs out of Databricks notebooks and into git projects for better version control. • Set up CI/CD with Jenkins and Artifactory for automating the build process of our projects. • Created a DC/OS cluster and dockerized our internal applications for easier deployment and infrastructure management. • Introduced Git Flow to the engineering team, established a release process for libraries and services, and focused on improving unit test coverage. • Led (and implemented) a project to improve security across our cloud infrastructure. • Extensive work in AWS with VPCs, EC2, EBS, EFS, Lambdas, API Gateway, and more. ### Senior Software Engineer @ Apteligent Jan 2015 – Jan 2017 | San Francisco Bay Area • Full-stack engineer on the data platform team, working primarily in Java, Scala, and Python (Flask). • Primarily tasked with writing Spark batch & streaming jobs, scheduling jobs in Azkaban, setting up and maintaining Kafka infrastructure, building out data processing pipelines, building out and maintaining our Cassandra cluster, and writing the API to collect and serve our data. • Often tasked to work in other components of our stack, including JavaScript UI frameworks (supporting legacy Backbone.js framework and building new features in our React framework), JavaScript API services (Node.js and Express), and Ruby (Chef configuration management). • Consolidated two separate collection and Kafka storage pipelines into a single pipeline, saving approximately 40% on monthly costs in AWS EC2 and EBS for the two tiers. • Redesigned and implemented Apteligent's integration with Zuora. • Assisted the SDK Agent team with work on Crittercism's iOS and Unity SDKs. • Led the development effort in moving deployment of internal services to Docker. • Managed deployments of services in production and pre-production environments. Responsible for setting up infrastructure in AWS and configuration management in Chef, as well as Consul for service discovery. ### Software Engineer @ Apteligent Jan 2014 – Jan 2015 • Building the front-end customer portal and user interface. • Involved in the design and implementation of features and solutions for the portal, platform APIs, and other systems to support a large scale multi-tenant SaaS application. • Collaborating with product owners to develop both private and public APIs. • Designing and developing front-end architectures and implementing business logic to support critical customer use cases including account management, usage monitoring, and billing. • Participating in agile development process (scrum). • Partnering with platform teams to ensure the maintenance of optimal customer portal and platform API strategies, standards, and best practices. Technologies: • JavaScript (backbone.js/node.js) • HTML + CSS (Less) • Python (Flask) Promoted after 11 months. ## Education ### Bachelor of Science (B.S.) in Biology, Molecular and Cellular University of California, Davis Jan 2009 – Jan 2012 ### Rio Americano High School ## Contact & Social - LinkedIn: https://linkedin.com/in/amdziuk - Website: http://adamdziuk.com/ --- Source: https://flows.cv/adamdziuk JSON Resume: https://flows.cv/adamdziuk/resume.json Last updated: 2026-03-22
