Highcharts development and integration in WordPres
Amazing work ethic and deliverables. I can highly recommend and will definitely use again on future projects.
The project was complex and included data integration with HighCharts and DataTables. Sometimes you don't know what you don't know ahead of time and he always was willing to provide the best solutions without compromise.
Communication was outstanding! His prior experience and knowledge of the subject was obvious and this goes a long way when you're unsure about hiring the right person for the project.
Above and beyond is what he provided and I couldn't be happier with the result!

Whether you're validating a new idea, launching an AI-powered SaaS MVP, integrating third-party APIs, or building a scalable React/Next.js + Supabase/Firebase platform, I can take your product from concept to production with clean architecture, rapid execution, and a focus on future scalability. I specialize in integrating modern AI capabilities using OpenAI and Claude APIs to build intelligent workflows, conversational assistants, content generation systems, and automation-driven products.
🚀 Full Stack Development
- Frontend: Next.js 14+ (App Router), React/Vite, Tailwind CSS, DaisyUI
- Backend: Node.js, Python (FastAPI, Django), PHP (Laravel, WordPress), Strapi
- Databases: Firebase, Supabase, PostgreSQL, MySQL, MongoDB
- Responsive, high-performance, SEO-friendly web applications
- Real-time features using WebSockets, Supabase, or Firebase
- Work with Firestore, Cloud Functions, Cloud Run, Cloud Tasks, Storage, Security rules, Hosting, and Secret Manager.
⚡ AI Prototype to Production (From idea to demo. From demo to scalable product.)
- Rapid AI-powered MVP builds using OpenAI, Claude, and open-source LLMs
- Chat interfaces, AI assistants, summarization tools, and automation workflows
- RAG pipelines for intelligent document and data processing
- Clean architecture from day one so your MVP scales without a full rewrite
- AI feature integration into existing SaaS platforms and web apps
- Validate ideas fast without sacrificing code quality or future scalability
🧱 SaaS and Product Development
- Taking rough prototypes, Figma files, or half-built products to a production-ready state
- Translating designs and specs into clean, maintainable, scalable codebases
- Refactoring MVP-stage code into solid production architecture
- Multi-tenant platforms, dashboards, admin systems, and role-based access
