About Mohamed

Senior Fullstack Engineer and AI Consultant, I assist companies, startups, and project owners in designing high-performing, scalable, and useful digital products.

With over 8 years of experience, I am involved from product ideation to deployment: scoping, architecture, UX, development, AI integration, automation, deployment, and optimization.

My expertise:

• Fullstack Web: React, Next.js, TypeScript, Ruby on Rails, Node.js, NestJS, Emberjs
• Mobile: React Native, Expo
• Backend & Data: REST API, PostgreSQL, Prisma, Redis, Supabase
• SaaS: multi-tenant, roles, subscriptions, payments, and dashboards
• Artificial Intelligence: OpenAI, open-source models, RAG, vision, and image generation
• Agentic AI: autonomous agents capable of analyzing, deciding, using tools, and executing business workflows
• Automation: API, n8n, Make, webhooks, CRM, content, and data processing
• Cloud & DevOps: Docker, CI/CD, Vercel, Railway, and AWS/S3

I can help with:

• creating an MVP, a business application, or a complete SaaS;
• taking over and modernizing an existing application;
• integrating AI features into your product;
• developing an AI agent connected to your tools and data;
• automating your repetitive processes and tasks;
• auditing your architecture, performance, or code;
• supporting your team in technical and product decisions.

My approach is pragmatic and results-oriented: understand the real need, choose a suitable architecture, quickly deliver a reliable first version, and then improve the product based on usage.

I work independently or with your product, design, and business teams. My goal: to build a high-performing, maintainable, secure, and profitable solution.
