Available to hire
I am a senior full-stack engineer with over 7 years of experience building high-converting, AI-powered SaaS websites and lead-generation funnels using Next.js and Tailwind CSS. I specialize in fast prototyping, Lighthouse performance tuning targeting a 90+ score, Stripe subscription embedding, and creating lightweight CMS-driven blogs and contact systems.
I have delivered polished MVPs within tight sprint windows, including 2-day rapid sprints, and helped lift demo bookings by 40% through conversion-driven UX and premium brand design using a white/gold/black palette. I bring strong adaptability to fast-paced product sprints and have a deep knowledge base to transform and augment product capabilities.
