Kashif Ahmad

I’m a results-driven Full-Stack Developer with 3+ years of professional experience designing, building, and shipping production-grade web applications and enterprise SaaS platforms serving 1.3M+ users. I’m equally strong across the full stack—frontend architecture with React.js and Next.js 16 (SSR/SSG/ISR), and backend services with Node.js, Express.js, REST and GraphQL APIs, backed by PostgreSQL schema design and query optimization. Across multiple platforms, I’ve owned end-to-end delivery: reusable component libraries, multi-tenant SaaS architecture with fine-grained RBAC, authentication and data security (JWT/OAuth2 with HIPAA/GDPR-aligned practices), real-time systems (WebSockets, BullMQ), and comprehensive testing (Jest, Testing Library, Cypress). I also build AI-powered features using Google Vertex AI (Gemini 2.5 Flash) and OpenAI (GPT-4/Whisper), and I deploy cloud-native releases with Docker and CI/CD on Google Cloud Run and AWS.
