Full Stack Developer for Fitness SaaS Platform

@point2solutions

# Senior Full-Stack Developer | Fitness Coaching SaaS Platform Hi, I read your brief carefully, and what stood out is that you're not looking for a developer to build screens—you're looking for someone to architect an operational system that can scale a proven coaching business from hundreds to thousands of clients. * Use structured coaching templates as the foundation * AI generates personalized sections rather than complete plans * Prompt caching for repetitive scenarios * Route simple tasks to lower-cost models * Use premium models only for complex cases * Log all AI interactions for optimization and auditing Lets connect... Thanks

PHP and Rails listed together usually means the backend language is still open for discussion. Worth pinning before Phase 1 starts, because the AI layer in Phase 2 needs a consistent API surface to build against, and retrofitting auth or data access patterns mid-project costs more than the decision itself. Here's how I'd structure the build: M1: Auth, coach/client data model, multi-tenant foundation, 31,875 INR, 5d. M2: Core SaaS features (workout/nutrition plan builder, scheduling, coach dashboard), 31,875 INR, 5d. M3: Client portal, progress tracking, AI recommendation layer, 31,875 INR, 6d. M4: Subscription/payments, onboarding, testing, production deploy, 31,875 INR, 5d. The multi-tenant schema shapes everything downstream. Coaches with multiple clients, clients potentially across multiple coaches, subscription tiers per coach - that relationship model needs to be locked before feature work starts on top of it. On the AI side: complexity varies a lot depending on whether you're targeting rule-based recommendations, LLM-driven plan generation, or something fine-tuned. Each has a different scope profile for Phase 2, and getting clarity on that before M3 kicks off means no surprises on the estimate. What's your current thinking on the backend stack, and is there existing user data or coach accounts being migrated into the new system?

Hi there, I can configure and brand your Listeo theme perfectly for Robochef24. Mapping your 4 distinct business verticals requires clean taxonomy mapping and smart conditional form logic. 1. Taxonomy & Custom Fields Sales & Rental: Setup subcategories with dedicated fields (Condition/Warranty vs. Rates/Deposit). AMC & Ingredients: Map durations and SLAs alongside packaging/shelf-life attributes. 2. Conditional Form Logic & Filters Dynamic Forms: Vendor submission forms will dynamically show/hide fields depending on the parent category chosen (e.g., hiding SLA fields when a vendor uploads Coffee Beans). Targeted Searching: Global filters (Brand, Location) combined with category-specific sidebars (Rental Period, Package Size). 3. Homepage Layout Build the 4 primary service cards linking directly to their target search pages. Set up the query limits to strictly cap listings at a maximum of 5 products per section. I have extensive experience customizing WordPress directory themes and can execute this setup cleanly. Let's connect on chat to get started! Best regards, Krish

With my 4+ years of experience in full-stack development, I am confident I can successfully contribute to the creation and implementation of your Fitness Coaching SaaS Platform. A notable project that demonstrates my capabilities in subscription-based services with payment integration is our work on www.xyz.com. This project, similarly to yours, demanded a multi-step onboarding process with client questionnaires and tailor-made subscriptions. One strength I possess is a thorough understanding of queue-based workflow systems, essential for the tiered system you require. Additionally, my expertise in using openAI/Claude API for plan generation and check-in response drafting would be significant for your AI integration. A prime example of the scale of projects I've handled is the 10x growth in usage witnessed by another subscription service we built. On availability and professionalism; daily communication through WhatsApp/Slack is second nature to me. Being based in India myself, this synergizes well with your preference while assuring constant contact throughout the development lifecycle. A competitive advantage that distinguishes me as a meticulous developer is my profound adherence to delivering quality work on time as per agreed milestones
