Overview

We're a healthcare technology company with a live dental practice management platform deployed on AWS. We're looking for an experienced full-stack developer to extend and harden our existing codebase by building several new modules and fixing/refining existing ones. This is a fixed-price engagement for a defined set of deliverables. All work builds on, integrates with, and extends our current platform. New code must be compatible with and deployable within the existing system, and must operate as native components alongside current functionality without disabling anything that already works. For each item below, your obligation is one of: Fix — the feature exists but is defective; identify the root cause and remediate so it works fully as specified. Build — the feature is absent; develop it from scratch and integrate it natively. Scope of Work / Deliverables Website Maintenance — Refine and improve the current marketing site; revise content and design, and add new sections/content as requested. Insurance Eligibility & Claims — Real-time eligibility checks and accurate out-of-pocket cost display driven by Explanation of Benefits (EOB) data, integrated via the Stedi EDI platform. Billing & Invoicing — Update the billing and invoicing interface for a more user-friendly experience, with integrations into the insurance/eligibility module. Dental Records & Treatment Plans — Treatment plan comparison, cost estimates, and digital restorative and periodontal charting with tooth-surface identification.
