Job description

Job Summary

We are seeking 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 replace a scattered mix of tools with one unified system spanning web, iOS, and Android - handling 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 ideal candidate is proficient in modern development frameworks, comfortable using AI-assisted development tools, and capable of delivering a polished, functional product on an accelerated timeline.

Key Responsibilities

• Build a cross‑platform application (web, iOS, and Android) from provided specifications, prioritizing native‑feeling performance for field use on mobile devices

• Integrate the application bidirectionally with GoHighLevel CRM via its REST API and webhooks (contacts, conversations, payments, automations)

• Implement 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

• Implement 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 implement 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 implementing 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

• Dependable, detail‑focused, and able to work independently with minimal supervision

• Ability 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

• Ability to provide architectural recommendations and suggest feature improvements
