Redis caching for hot data, BullMQ job queues across 40+ data-collection adapters, PostgreSQL with strategic indexing (license plates, VINs, timestamps) and partitioned historical tables, 2Captcha for anti-bot protection, and WebSocket for live data-processing progress. ## Results - 60M+ vehicle records, <100ms query response times - 40+ concurrent data sources with intelligent throttling - Revenue via paid vehicle-history reports - 99.9% uptime --- # Case Study: Stellar — Real Estate Investor Portal - **Client:** Florida real estate development firm - **Role:** Full-stack solo developer (C5H) - **Duration:** 8 weeks - **Live:** https://status.livestellar.com/ - **Stack:** Next.js 15, React 19, TypeScript, TailwindCSS, SQLite, Knex.js, NextAuth 5, AWS S3, Resend, Framer Motion ## Summary A sophisticated CRM and investor communication platform managing 100+ concurrent real estate development projects with real-time updates, Git-like version control, and granular access management. ## The Challenge A Florida firm struggled to keep 250+ investors informed about 100+ active construction projects using spreadsheets, email threads, and manual photo sharing — causing missed updates, conflicting information, hours of manual onboarding, and no granular permissions or read-tracking. ## The Solution A custom investor portal that works like "GitHub for real estate projects": version history with rollback, staged rollouts, granular role-based permissions (admin/client/viewer), magic-link auth, dual A/B dashboards, per-project theming, and automated email notifications via Resend. Photos and assets on AWS S3. ## Results - 94% investor satisfaction - 15 hours/week of admin time saved - Instant updates vs. previous 24-48 hour delays - 2-minute investor onboarding vs. 45 minutes manual - 500+ tracked project versions, 99.9% uptime --- # Case Study: Proyect.ar — AI Architecture Rendering SaaS - **Client:** Internal SaaS product - **Role:** Full-stack solo developer (C5H) - **Duration:** 3 months - **Live:** https://proyect.ar - **Stack:** Next.js 15, OpenAI API, DALL-E, Gemini, SQLite, NextAuth, MercadoPago, Sharp, TypeScript, TailwindCSS ## Summary AI-powered SaaS generating photorealistic architectural renders from sketches, floor plans, and 3D models. Features credit-based billing, a referral system, 8+ rendering styles, and MercadoPago payments. ## The Challenge Architects, interior designers, and real estate developers needed an affordable, fast way to produce photorealistic renders from rough sketches. Traditional 3D rendering means $500-2000/year software, high-end GPUs, steep learning curves, and hours or days per render. ## The Solution A complete SaaS using OpenAI DALL-E and Google Gemini to generate renders from uploaded images in minutes. Credit-based billing, referral rewards, 8+ architectural styles (modern facades, minimalist interiors, luxury, landscaping), image processing with Sharp, and a smooth upload-to-download flow. ## Results - Active user base generating renders daily - Automated credit system handling payments and usage - Referral system driving organic growth - Landing page converting leads to paid users
