Aysun I.

I help founders and small teams build, fix, and improve production web apps, SaaS dashboards, APIs, and AI automation workflows. I’m a Senior Full-Stack Developer with 8+ years of experience across React, Next.js, TypeScript, Node.js, PostgreSQL, MySQL, TypeORM, Prisma, Supabase, REST APIs, PHP/CodeIgniter, and AI/API integrations. I’m usually most useful when a product is already real — users depend on it, the codebase has history, bugs are blocking progress, workflows are messy, and the team needs someone who can understand the system and ship carefully without breaking existing users. Here’s what I can help with: 1. Full-Stack Web Apps * React, Next.js, TypeScript, Node.js * SaaS dashboards, admin panels, portals, booking/contact flows * Clean UI implementation connected to real backend data 2. Backend, APIs & Databases * REST APIs, webhooks, integrations, auth, roles and permissions * PostgreSQL, MySQL, TypeORM, Prisma, Supabase * Database workflows, migrations, reporting logic, and production bug fixes 3. AI & Automation Workflows * OpenAI / Claude API integrations * AI-assisted business workflows, email automation, AI receptionist-style systems * n8n-style automations, structured outputs, lead/customer communication flows 4. Existing Product Takeover & Debugging * Understanding inherited codebases * Fixing complex business logic * Improving reliability, performance, and maintainability * Clear communication about what is risky, what is broken, and what should be fixed first I have worked on production systems involving registrations, permissions, user/admin workflows, payment-related logic, emails, dashboards, reporting, and business-critical processes. I also have a scientific background in chemistry and computational research, which helps me work well on structured-data products, AI workflows, healthcare/science-related tools, vendor assessment systems, and complex business logic. I’m Turkish, work internationally, and communicate clearly in English and Turkish. I work well with founders and teams who value practical decisions, honest communication, and reliable delivery.
