Usama A.

Senior AI SaaS Engineer | Next.js, Supabase, Multi-Tenant Platforms

I build complete AI SaaS products from idea to production. I work end to end across product architecture, frontend, backend, database design, multi-tenancy, authentication, AI integrations, subscriptions, transactional email, deployment, scaling, and ongoing operations. My primary stack includes Next.js, React, TypeScript, Node.js, Supabase, PostgreSQL, Stripe, Resend, Vercel, and VPS infrastructure. For AI functionality, I regularly integrate OpenAI, Claude, and Perplexity APIs. I have 8+ years of experience and have built more than 30 SaaS and web products. Recent platforms I built end to end include: • Affiliate Aura: A multi-tenant platform with business and creator dashboards, Shopify integration, tracked referrals, commission workflows, analytics, and AI script-to-video campaign generation. • Peakfai: An AI SEO automation platform covering keyword research, content generation, WordPress publishing, LinkedIn and X automation, rank tracking, and visibility monitoring across AI search engines. • Arkoro: An AI image and video SaaS for commercial real estate, with virtual staging, image enhancement, furniture removal, bulk processing, cinematic video generation, subscriptions, and credit-based usage. • Vesperly: A security-sensitive digital succession platform featuring zero-knowledge encryption, advisor and client portals, heartbeat monitoring, executor verification, controlled data release, and audit trails. • Carbon Heroes: An AI-powered environmental social-value platform that generates location-specific strategies, performs scientific calculations, aligns results with UK procurement frameworks, and produces reporting-ready bid content. I can help you build: • Multi-tenant SaaS platforms • AI agents and automated workflows • SaaS MVPs from concept to launch • Secure dashboards, admin panels, and customer portals • Subscription and credit-based billing with Stripe • OpenAI, Claude, Perplexity, Shopify, WordPress, and third-party API integrations • AI content, image, and video generation systems • Supabase authentication, PostgreSQL, RLS, storage, Edge Functions, realtime features, and scheduled processes • Vercel deployments and VPS infrastructure for background workers, queues, and scaled workloads • Existing product rebuilds, performance improvements, and production scaling I do not only implement individual screens or isolated features. I take ownership of the complete product, make practical architecture decisions, and stay responsible as it moves from an early idea to a live, scalable platform.
