Lasha K.

Need a SaaS or AI product that can handle real customers, not just look good in a demo? I help startups build, fix and scale production products, backed by $350K+ earned, 8,000+ hours, a 100% Job Success Score and Top Rated Plus status on Upwork. Most of my work is with React, Next.js, TypeScript, Supabase and PostgreSQL. I’m strongest in frontend and product engineering, but I’m not limited to the UI. I can take ownership of architecture, APIs, data, authentication, performance and deployment. One recent project involved interfaces handling more than 100K real-time rows. I reworked how the UI processed and rendered updates, reducing interaction latency by 40%. On another product, I helped improve the checkout journey and reduced customer drop-off by 35%. I work independently, communicate clearly and speak up when I see a decision that could create problems later. A long-term client described me as “a dream to work with,” which is the kind of working relationship I aim to build. Send me a short description of your product and the main problem you need solved. I’ll suggest a sensible first step.
