Muhammad Faheem M.

I'm a Senior Full-Stack Engineer with 8+ years of experience building, scaling, and maintaining production SaaS platforms, AI-powered applications, APIs, cloud systems, and Adobe ColdFusion applications. I work across the full stack, from frontend and backend development to databases, integrations, infrastructure, and production support. My core stack includes Next.js, React, TypeScript, Node.js/NestJS, PostgreSQL, Supabase, AWS, Docker, AI/LLM integrations, Adobe ColdFusion, Lucee, and CFML. 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐮𝐢𝐥𝐝 𝐚𝐧𝐝 𝐬𝐨𝐥𝐯𝐞: ⦿ SaaS platforms and multi-tenant applications ⦿ AI-powered features, LLM integrations, and document processing ⦿ Next.js and React applications ⦿ Node.js, NestJS, REST APIs, and backend systems ⦿ PostgreSQL, Supabase, MongoDB, Redis, and data modeling ⦿ Stripe, banking, CRM, Google Workspace, and third-party API integrations ⦿ Authentication, RBAC, webhooks, background jobs, and complex workflows ⦿ AWS, Docker, CI/CD, Vercel, and production deployments ⦿ Performance optimization, debugging, and modernization of existing systems 𝐑𝐞𝐜𝐞𝐧𝐭 𝐫𝐞𝐬𝐮𝐥𝐭𝐬: ⦿ Reduced API response times by 30% through database redesign, query optimization, indexing, and Redis caching. ⦿ Built a reusable multi-tenant finance platform supporting AI document processing, Open Banking, invoice workflows, transaction reconciliation, and business automation. ⦿ Built and shipped a multi-tenant sports platform with player profiles, video training, progress tracking, dashboards, gamification, real-time match data, and admin workflows. ⦿ Built AI-powered workflows using OpenAI for document processing, structured data extraction, customer summaries, and personalized experiences. 𝐀𝐝𝐨𝐛𝐞 𝐂𝐨𝐥𝐝𝐅𝐮𝐬𝐢𝐨𝐧 / 𝐋𝐮𝐜𝐞𝐞 / 𝐂𝐅𝐌𝐋: I work with Adobe ColdFusion, Lucee, and CFML applications that need maintenance, bug fixes, upgrades, server setup, database work, API integrations, performance improvements, or modernization. I’m comfortable working with existing ColdFusion codebases and legacy systems where changes need to be made carefully without breaking what already works. I take ownership from requirements and architecture through development, deployment, and production support. I’m comfortable joining an existing team, improving an existing codebase, or taking a product from idea to production. If you need a senior engineer who can understand the problem, build the solution, modernize an existing system, and own the outcome, let’s talk.
