I’m a Frontend Developer with 3+ years of experience building scalable SaaS platforms, internal workflow systems, and data-driven user experiences. I focus on turning complex processes into intuitive interfaces—so teams adopt the product quickly and keep using it. At Sistran, I was Sole Frontend Developer for a workflow platform replacing Jira. I drove 100% adoption across 820+ internal users in 17 countries, then enabled rollout to 100+ enterprise clients within 2 months—eliminating ~$3K/license fees per client ($300K+ savings) and contributing to new business revenue. I engineered 380+ configurable workflows with dynamic state management and task tracking, designed role-based systems for 9 user types, and architected a scalable multi-tenant frontend using React so the platform could evolve into a globally adopted SaaS product. Earlier, at Scalabl, I redesigned video playback and progress tracking, increasing course completion rates by 35% across a global platform serving 2,500+ professionals in 50+ countries; today, in active builds, I’m extending marketplace and SaaS experiences with React/TypeScript, Firebase, and Node.js (including AI-driven natural-language analytics and real-time dashboards), always aiming for modular, scalable solutions.
