Senior full-stack developer building scalable SaaS and cross-platform apps with React, NestJS, and AI-augmented engineering.
What I'm looking for
I’m a Senior Full Stack Developer with 7+ years building SaaS products, web platforms, mobile applications, and backend systems. I specialize in React, React Native, Angular, TypeScript, NestJS, PHP, and Laravel—translating complex requirements into production-ready solutions from concept to deployment.
In my current role (Home Power), I led the evolution of a solar-industry commission management ecosystem spanning web, mobile, backend, CRM, and ERP integrations. I architected and built a React-based SaaS platform for commission management (payouts, chargebacks, invoicing, audit workflows, and financial reporting) and implemented a NestJS backend with 13+ domain modules backed by PostgreSQL.
I build high-performance frontend experiences with TypeScript and modern state/query patterns, and I develop mobile capabilities in React Native, including native integrations in Swift and Kotlin plus GPS-based functionality. I also created custom Odoo modules and operational tools to support business workflows and company-level customization.
I’m passionate about AI-Augmented Engineering, applying multi-agent development workflows, Spec-Driven Development, and AI-assisted practices to improve software quality, accelerate delivery, and raise engineering productivity. I’ve also delivered full lifecycles across logistics, e-commerce, and business-management platforms, including real-time tracking and payment integrations, and strengthened reliability through monitoring and modernization initiatives.
