Senior Frontend Engineer leading scalable React/Next.js architectures for B2B SaaS and analytics platforms.
ZimbabweWhat I'm looking for
I’m a Senior Frontend Engineer / Lead Frontend Developer with 5+ years building complex B2B, B2C, and SaaS products. My focus is frontend architecture, complex business logic, and high-load interfaces using React, Next.js, and TypeScript.
Over my career I’ve helped create and evolve 8+ products—from SaaS platforms and analytics systems to admin panels, media services, educational platforms, visual editors, and CAD-configurators. I’ve designed frontend architectures, UI libraries, design systems, typed API layers, and data strategies, owning the full lifecycle from technical decisions and architecture through releases, scaling, and production support.
I’m especially proud of measurable improvements: caching and performance work that accelerated new module development by 25–75% and reduced integration errors by 25–35%, plus Core Web Vitals improvements (LCP, CLS, INP). I also invest heavily in code quality via code review, mentoring, CI/CD improvements (GitLab), and monitoring production issues with Sentry.
