# Hannah Spence > Senior Software Engineer Location: Avon Lake, Ohio, United States Profile: https://flows.cv/hannahspence Whether I’m baking bread or building an app, I am always interested in how I can break a problem down into smaller tasks. This motivating force carries over to my natural enthusiasm for getting behind a brand and achieving goals together as a team. My full-stack experience allows me to quickly switch gears from refining UI to the pixel, retro-fitting a new service to legacy code, or building new applications with the latest technologies. As a team member, I seek out opportunities to both discover and assist to ensure clear milestones for success. ## Work Experience ### Senior Software Engineer @ RealWork Jan 2025 – Present | Cleveland, Ohio, United States Focused on building seamless, customer-first product experiences and delivering reliable integrations that connect tools, data, and people. • Led the design and launch of an Onboarding Wizard, transforming the first-time user experience to deliver immediate value and reduce customer support needs — creating a more “magical” start for new customers. • Introduced structured scoping practices to uncover unknowns early, clarify timelines, and improve project predictability across teams. • Drove the Jobber Golden integration, managing historical data imports and review mapping to strengthen platform connectivity and streamline customer workflows. • Led the CompanyCam Golden integration from design through delivery, implementing OAuth, data imports, and review mapping to expand ecosystem integrations and enhance partner data flow. • Owned the social posting enhancement initiative, launching AI-powered description generation and a smarter post-selection algorithm that reduced errors and improved reliability. • Revived Facebook Business posting, re-enabling customers to publish content across a key marketing channel. • Implemented Instagram OAuth and posting, extending the platform’s social media capabilities for multi-channel publishing. • Delivered all major initiatives on schedule, maintaining consistent execution and reliability even in a part-time capacity. ### Software Engineer @ RealWork Jan 2022 – Present • Worked on customer-facing mobile application, prioritizing performance for low connectivity • Enhanced mobile and web application to allow 2000+ businesses to easily categorize their services for sales and customer filtering • Built internal tools with React, TypeScript, Parse, and Back4App tested with Jest and Cypress for customer service representatives to schedule, review, update, or delete client SEO data. • Created a hiring partnership with engineering bootcamps with over 10,000 total graduates, reducing recruiting expenses ### Software Engineering Manager @ RealWork Jan 2023 – Present • Automated smoke tests by migrating E2E testing from paid Cypress suite to open-source Playwright platform to reduce flaky tests with CI on GitHub, saving the company 1000 hours annually in engineer labor • Empowered 2000+ users on web and mobile to easily categorize their services for sales and customer filtering with Parse Platform and Back4App for low-cost data management and React and MUI for UI • Addressed inefficiencies within the QA team with Agile, resulting in a 50% increase in sprint velocity for QA team • Developed a streamlined portal for homeowners using Express.js and styled React components, enabling business reviews on web/mobile devices, integrating with Google and Facebook for over 1,000 businesses • Mentored a junior engineer to support their career growth and advancement, establishing objective measurements and setting weekly SMART goals aligned with their career aspirations, resulting in successful promotion and salary increase ### Software Engineer @ Talroo Jan 2020 – Jan 2022 | Austin, Texas, United States • Secured user data and supported data transparency by ensuring CCPA compliance with Dockerized application and extracting user data across greenfield and legacy code bases for over 30 million users • Leveraged AWS Lambda and S3 to efficiently handle user responses, employing provisioned concurrency to optimize resource allocation and ensure consistent performance during peak loads • Saved Talroo over $100K annually with low-cost SMS job alert service with Bandwidth and AWS CloudWatch analytics • Enabled SEM to target audiences by adding Google Analytics and Google Tag Manager data hooks on popular job search site with 1 billion monthly hits • Centralized documentation for regression tests, common bug fixes, and general code base knowledge ### Associate Software Engineer @ Talroo Jan 2019 – Jan 2020 • Modernized UI of site with 30 million users, increasing revenue 15%, improving user experience based on A/B tests and consistent styling with a Material UI-based component library • Implemented pre-qualification questions increase job applicant quality with Flask and SQLAlchemy for relational data management and SurveyJS for rendering complex forms, increasing customer spending up to 10 times more per user ### Software Engineer @ Self Jan 2018 – Jan 2019 Dex: Full Stack Engineer https://github.com/hratx-blue-ocean/hratx42-Dex • Designed database models and wrote user route handlers as RESTful routes for clear and predictable handling of data.
