Franklin García Marín

Building and shipping Flutter + Firebase apps solo, developed spec-first and executed through self-designed agentic workflows, with release automation treated as part of the product rather than an afterthought.

• Kleio: a Flutter + Firebase app currently in open testing on Google Play, built, signed and uploaded by a fully automated GitHub Actions pipeline.
• Adepha (in progress): a food intake tracking app with a companion admin web app that lets nutritionists link to their patients' information and follow their progress.
• Both apps developed using Spec Driven Development and agentic workflows designed in-house: the spec is the contract the agent implements against and the artifact under review, not the generated diff.
• Authored reusable skills carrying repo conventions, delegated scoped work to subagents, and built the surrounding harness — tooling reach, guardrails and review gates — so anything irreversible stays in front of a human.
• Defined the Flutter + Firebase deployment pipeline as an executable spec — guarded deploy scripts, per-environment Firebase projects and CI-injected configuration — then reused it across projects.
• Automated deployment of this site to shared hosting via GitHub Actions, so publishing is a single merge to main.
• Owning every layer end to end — architecture, implementation, release engineering and store management.

Senior Android engineer and tech lead across client engagements, most recently adopting an AI-first, prompt-driven development workflow.

• Zocdoc: early member of a newly formed retention-focused team, consuming GraphQL endpoints as the platform migrated off a monolithic backend.
• Engaged as staff augmentation at Zocdoc but drew on lead experience to improve the process — identifying that the team lacked coordination with QA, and advocating for a dedicated QA member to define test coverage for the work being shipped.
• Adopted an AI-first, prompt-driven Android workflow at Zocdoc — shifting from hand-written code to LLM prompting, then to authoring reusable skills and coordinating subagents.
• Tech Lead for Finish Line's in-store Android suite: coordinated with the Product Owner, design team and stakeholders to shape features, turn them into tasks and implement them, then mentored developers as the team grew.
• Architected and led a full Kotlin-first migration and adoption of Jetpack Compose across Finish Line's modular codebase.
• Built native Android apps for in-store price updates, integrating Bluetooth printing via ZPL so associates could print updated shelf labels.
• Owned Finish Line's build and release pipeline end to end: configured Jenkins, then led the move to Bitrise. The suite never shipped to Play — it went to a corporate Mobile Security System governing every in-store device, so builds landed in a shared drop location and the MSS distributed them to the fleet.
• Merged two standalone apps into a unified application, partnering with UX/UI designers on consistent, responsive interfaces.
• Tech Lead on the DaVita Patient Engagement platform across Android, iOS and Web: defined and scoped tasks, raised flags and risks early, and coordinated the web, QA, iOS and Android teams alongside the Product Owner — including quarterly scaled planning through scrum-of-scrums — while staying hands-on through development, code review and shipping.
• Built privacy-focused messaging features for Wappo on Firebase and QuickBlox, with gesture-based content obfuscation.
• Gorilla Labs R&D: an NFC proof of concept for Android and iOS, and a native Android app streaming live video to AWS Rekognition and Kinesis for real-time facial recognition.
