Bio

As a Software Engineer and Developer with over 16 years of experience, I specialize in building SaaS products that help users accomplish their goals more effectively. I have worked extensively with startup teams to build features that directly impact user acquisition and retention, collaborating closely with product managers, designers, and marketing teams to understand user behavior and optimize conversion funnels. My experience spans the full stack with TypeScript/JavaScript, Node.js, Go for backend services, and frontend frameworks like Vue and React, with deployment experience on AWS, GCP and Kubernetes. I have developed a passion for Flutter as a cross-platform development. I think strategically about user journeys and change management, delivering systems that perform well under growth pressure.


Leadership and Achievements

  • User-Focused Product Development: I have built SaaS features that directly improved user experiences, including workflow optimizations that increased task completion rates and onboarding improvements that reduced early user drop-off. 
  • A/B Testing & User Research: I have designed testing frameworks to measure how interface and workflow changes affect user behavior, working with product teams to make data-driven decisions about feature development.
  • Startup Environment Experience: I thrive in fast-paced environments where priorities shift quickly, having worked with small cross-functional teams to ship features rapidly while maintaining quality and user focus.
  • Full-Stack SaaS Development: I have experience building complete user experiences from signup flows to complex application features, using TypeScript/JavaScript, Node.js, and modern frontend frameworks.
  • Performance & Reliability: I consistently deliver systems that perform well under pressure, achieving sub-2 second response times for complex operations while building for scale as user bases grow.
  • Cross-Team Collaboration: I work effectively with product managers, designers, and marketing teams to understand user needs and translate them into technical solutions that drive business outcomes.


Skills

  • Full-Stack Development: I have 16+ years of experience with TypeScript/JavaScript and Node.js, with strong frontend skills in Vue.js and React for building responsive user interfaces.
  • Growth & User Experience: I have experience with A/B testing frameworks, user onboarding optimization, signup flow improvements, and building features that help convert and retain users.
  • SaaS Product Development: I have worked on subscription billing systems, user dashboard interfaces, in-app messaging, and the types of features that help SaaS companies grow their user base.
  • Performance & Architecture: I consistently deliver systems with sub-2 second response times, design for scale as user bases grow, and optimize database queries and API performance.
  • Collaboration & Process: I work well with product managers, designers, and marketing teams, adapting quickly to changing priorities while maintaining code quality and user focus.
  • Technical Foundation: PostgreSQL database design, API architecture, AWS cloud environments, CI/CD pipelines, automated testing, and modern development practices.
