Product Engineer specializing in TypeScript, GraphQL, and growth-driven SaaS scaling.
RomaniaWhat I'm looking for
I am a Product Engineer with 7+ years building and scaling SaaS platforms, combining strong technical execution with product intuition to deliver measurable outcomes. I thrive in remote, asynchronous teams and prioritize clear communication and ownership.
I've led product and engineering at fast-scaling startups and contributed to global enterprise systems, delivering results such as 10x user growth, 1.5M+ profile AI pipelines, and 30%+ reductions in repetitive work through automation.
My day-to-day work centers on TypeScript, React, GraphQL, NextJS, NestJS, NodeJS, PostgreSQL and AWS; I design APIs, growth funnels, and data pipelines while owning analytics and A/B testing to improve activation and retention.
I seek roles where I can lead product-focused engineering work, drive measurable growth, and implement scalable systems that reduce manual work and accelerate business impact.
