Web and Mobile App Developer

Job Summary: We're eager to welcome a skilled full-stack developer to build a custom practice management application from the ground up for a veterinary services practice. The goal is to swap a scattered mix of tools for one unified system spanning web, iOS, and Android — covering clinical records, scheduling, payments, tasks, and team communication inside a clean, fast user experience. The app must integrate bidirectionally with GoHighLevel (CRM and automation) via its API and connect to several third-party services. The right candidate is proficient in modern development frameworks, comfortable using AI-assisted development tools, and able to deliver a polished, functional product on an accelerated timeline.

Key Responsibilities:

• Build a cross-platform application (web, iOS, and Android) from provided specifications, putting native-feeling performance first for field use on mobile devices
• Integrate the application bidirectionally with GoHighLevel CRM via its REST API and webhooks (contacts, conversations, payments, automations)
• Set up secure user authentication with role-based access control and an audit trail of who edited what and when
• Develop an append-only, compliance-critical logging module with database-level safeguards (e.g., triggers) that prevent edits or deletions
• Build offline data entry that syncs automatically when connectivity returns, alongside real-time multi-user updates
• Wire up third-party integrations including communication/SMS (e.g., Twilio or via the CRM API), scheduling (Google Calendar), payment processing, and partner webhooks/email parsing
• Build both client-facing and internal-use interfaces, including clinical records, intake forms, structured notes, task management, and a unified messaging inbox
• Design and build a configurable pricing calculator with dynamic payment-link generation
• Test, debug, and document the application thoroughly, including setup and maintenance guides
• Collaborate with the business owner to refine features and recommend architectural improvements during development

Mandatory Skills:

• Proven experience in full-stack web and mobile application development, including cross-platform delivery across web, iOS, and Android
• Strong knowledge of API integrations, particularly with CRM and communication platforms
• Proficiency in modern development frameworks and programming languages (e.g., React Native/Expo, Flutter, or equivalent)
• Solid experience with relational database design and management (PostgreSQL / Supabase or similar)
• Experience setting up secure authentication, role-based access, and audit trails
• Strong problem-solving, debugging, and quality assurance skills
• Clear communication skills for collaborating with non-technical stakeholders
• Reliable, detail-oriented, and able to work independently with minimal supervision
• Able to deliver a complete, production-ready product on a tight timeline

Preferred Skills:

• Experience with AI-assisted development tools and workflows
• Familiarity with GoHighLevel's API and integration ecosystem
• Experience with offline-first sync solutions (e.g., PowerSync, WatermelonDB) and real-time data sync
• Knowledge of Twilio for SMS, voice, or messaging features
• Experience building healthcare, veterinary, or practice-management software
• Familiarity with Google Calendar API, payment-processing APIs, and webhook-based integrations
• Experience integrating AI features such as voice/meeting dictation or natural-language data querying
• Able to provide architectural recommendations and suggest feature improvements

Why Join Us: This is a high-impact build where you'll create a purpose-driven application from scratch for a practice focused on compassionate care. You'll have real technical ownership — the freedom to choose your stack, use AI-assisted tools, and shape the architecture around a clear vision. If you love turning a messy set of tools into one elegant product with genuine real-world impact, this is an exciting chance.
