Introduced dependency injection to allow for better component isolation which facilitated automated testing to improve development lifecycle time and enable continuous CI/CD. Also implemented strong typing (JS -> TS) to improve DX and efficiency. Integrated third-party components for text (transcript) authoring, and built high-quality clientside media recording. Also participated in making product decisions, planning the roadmap, gathering data about customer feedback/requirements, customer support/triage, etc. ### Software Engineer @ Optic Jan 2021 – Jan 2021 Designed and built backend/frontend/data model for the MVP of a new product in the developer- tools/API space. Data model based on DDD/CQRS concepts to enable git-style fork/merge collaboration on API shapes. Implemented in Rust for correctness, performance, and ease of sharing core logic available via WASM to CLI, frontend, backend. ### Co-Founder @ Narwhal Systems Jan 2014 – Jan 2021 | Rochester, New York Area Co-founded field data management company. Collection logic including real-time conditional validation with javascript-based predicates, relational/nested data, and guided collection procedures all contained within a fully customizable mobile app. Data synced to cloud where managers can view realtime data, respond to events, and run reports on data in their domain, as well as allowing data owners to share and collaborate with other stakeholders with confidence that private data stays private. NodeJS microservices written in Typescript, accessed through a unified GraphQL API gateway, all deployed on Kubernetes cluster with full end-to-end GitOps CI/CD pipeline running in Gitlab. Mobile app was written on React Native leveraging core data engine written ontop of RxJS, RxDB, SQLite to handle data integrity, validation, syncing, presentation etc. Web UI is written in functional React using Redux, Material UI. Designed data model iteratvely, going from specific single-use model to generalized model over time, as generalizations became clear. Interacted with customers, elicited requirements, and delivered on time. ### Software Consultant @ Designspring, Inc. Jan 2014 – Jan 2020 Working in collaboration with Designspring Inc. and the music department at McGill University to design and develop a computer controlled analog harpsichord. The computer will record and control the position of the instrument’s keys as they are played. This is useful to study how it is played in different situations, as well as to play back recorded music at higher resolution and accuracy that would be normally possible using a standard MIDI file. - Developing interactive Web UI to control the harpsichord’s state, including starting and stopping playback, record mode, MIDI input mode, etc. - Designing and implementing a state machine and series of states and possible transitions to control the harpsichord’s different modes of operation - Designing and implementing the control systems that run the harpsichord. Including reading from low level inputs, writing to outputs, keeping time in sync, etc. - Reading a subset of the MIDI protocol so the device can act as a simple MIDI instrument ## Education ### Bachelor of Science - BS in Software Engineering Rochester Institute of Technology Jan 2015 – Jan 2020 ### Allendale Columbia School ## Contact & Social - LinkedIn: https://linkedin.com/in/jashearer - GitHub: https://github.com/jshearer --- Source: https://flows.cv/josephs JSON Resume: https://flows.cv/josephs/resume.json Last updated: 2026-03-22
