Challenge

Connect user goals and progress information to useful model-backed fitness workflows without treating free-form generation as validated application state.

Approach

Build a bounded integration between product inputs, model-backed services and application responses. Confirm any personalization or outcome claims against owner-provided evidence.

Architecture

Product goals and history to AI integration service to Validated application response, simplified regimenai architecture
Simplified implementation boundaries. Rendered from the Mermaid source included with this case study.

Key features

Concept illustration for RegimenAI — AI Health Platform

Technical concept illustration. The case study below describes the project implementation.

Generic fitness plans ignore the fact that user progress isn't linear. RegimenAI is an AI-powered fitness platform generating personalized workout and nutrition plans based on a user's goals, history, and progress, built around a feedback loop rather than a one-time generation step — plans adapt based on what a user actually completes and reports back, moving beyond static, one-size-fits-all templates.

What I Built

  • Personalization engine generating recommendations from goals, history, and constraints
  • Progress tracking that logs activity and adapts plans over time
  • LLM-assisted plan generation for both workouts and meal plans
  • Feedback loop where plans adjust based on completion rates and explicit user feedback

Tech Stack

  • Backend: Python, FastAPI
  • AI: LLM-based plan generation
  • Database: PostgreSQL
  • Frontend: React

Key Decisions

  • Built a feedback loop where plans adapt based on completion rates and explicit user input, rather than a one-time generation step, since static plans ignore the reality that user progress isn't linear
  • Used FastAPI for the backend to keep the personalization and plan-generation endpoints fast and typed, appropriate for a service making frequent small requests as users log progress

Outcome / Impact

Delivered a platform that produces genuinely personalized fitness plans that evolve with the user, rather than static templates handed out once and forgotten.
