I'm Hassan, a full-stack architect specializing in Next.js and Node.js SaaS systems. I review your current architecture — codebase, database, infra — and hand you the top risks and a prioritized fix list, no pitch.
WHAT I REVIEW
Focused technical reviews for SaaS teams building for their next stage.
Multi-tenant systems, database design, and infrastructure that holds up as you grow. Built and scaled klic.gg, a multi-tenant SaaS platform.
Retrieval-augmented generation, voice agents, and AI-powered workflows. Built Voxility AI, an AI SaaS platform that consolidated 5 separate communication channels into one AI voice/chat agent using RAG and Twilio. Where prompt engineering meets system design — I build the AI pipelines and make sure the infrastructure underneath can handle them.
Platforms that can't go down. Delivered infrastructure for camposviola.ngo, a documentary film and media organization serving 400,000+ users via AWS S3/CloudFront, and CPPA-G, a national government system.
Third-party integrations, payment systems, and webhook pipelines that connect cleanly and fail gracefully. Built Twilio-powered voice/SMS integration into Voxility AI's multi-channel agent.
Schema design, migrations, and performance tuning for PostgreSQL and Supabase. Designed multi-tenant data architecture for klic.gg.
Deployment pipelines and CDN setup built for scale. Delivered AWS EC2, S3, and CloudFront infrastructure for camposviola.ngo, serving 400,000+ users.
PORTFOLIO
Systems designed for scale, reliability, and real-world complexity.
AI Communication Platform
Multi-channel AI SaaS platform with RAG-powered retrieval, voice agents, and Twilio integration, consolidating 5 communication channels (SMS, email, WhatsApp, voice, social) into one AI agent, fully synced with the client's CRM.
CPPA-G | National Electricity System (Govt.)
Built a national government electricity-sector system using Next.js, Node.js, and PostgreSQL. Case study details available on request given the sensitivity of government-system work.

camposviola.ngo
Rebuilt the platform's entire infrastructure for a documentary film and media organization — EC2 production environment with Nginx, PM2, and automated CI/CD via GitHub Actions. Decoupled media delivery with S3 and CloudFront. Built a fully interactive four-language experience (German, English, French, Spanish) with language-aware URL routing, serving 400,000+ users.
"Hassan is far more than a developer — he's a systems architect, a strategic collaborator, and someone who genuinely elevates the quality of the work he touches."
klic.gg
Performance and code-health work on a multiview livestreaming platform for gaming, esports, and live content. Improved both frontend and backend response speed, and refactored existing component and code structure to make the codebase easier to extend and maintain.
