Senior Software Engineer with 8+ years of experience building SaaS platforms, AI-powered applications, internal tools, customer-facing products, and startup MVPs.
I've worked as a Founding Engineer, Senior Software Engineer, and Product Engineer across startups and established companies, helping teams take ideas from concept to production. I build MVPs that are production-ready, and ship faster than traditional dev cycles. I help founders and teams go from prototypes to revenue-ready apps in a whim.
I specialize in:
-> Building modern web applications with React, Next.js, TypeScript and Node.js
-> Designing scalable frontend architectures
-> Developing AI-enabled products using OpenAI, Claude and LLM integrations
-> Building startup MVPs quickly without sacrificing quality
-> Integrating APIs, analytics, authentication and payment systems
Recent work includes:
• AI-powered content and productivity tools
• Climate-tech applications serving thousands of users
• SaaS platforms with complex user workflows
• Internal business tools and dashboards
• Customer-facing web applications
If you're looking for an engineer who can contribute beyond implementation and help shape product decisions, architecture, and user experience, I'd be happy to discuss your project.
