Kuldeep S.
AI Integration Expert | Full-Stack, Web & Mobile Developer | QA | 14+y
Overview: Your AI feature might be losing you clients right now. Bolted-on, context-blind, prompt-broken — most "AI integrations" fail quietly. I fix that. Then I build everything around it. I'm Kay. Top Rated. 14+ years in software delivery. Founder of a senior dev team that backs every project I take on. You get agency depth. You get one point of contact. No handoffs. No confusion. Where I deliver: 🔹 AI & Automation — LLM integration (OpenAI, Claude, Gemini). Prompt engineering. AI chatbots and agents. Context-flow fixes. Workflow automation (n8n, Make, Zapier). 🔹 Full-Stack Development — React, Next.js, Node.js, PHP/Laravel. REST APIs. Headless CMS. Shopify (custom Liquid). WordPress/WooCommerce. 🔹 Mobile Development — Flutter. React Native. Push notifications. Real-time dashboards. API integrations. 🔹 QA & Testing — Manual and automated QA. Cross-browser. Mobile QA (iOS/Android). Performance testing. Bug tracking. Most developers pick one lane. I built a team to cover all four. That means you're not managing four freelancers and hoping they talk to each other. Recent work: LinkLaunch.ai (US) — AI-powered career coaching platform. Dashboard redesign, ongoing technical delivery. CHBO (US) — Web testing & platform enhancements. Fairies AI / Altera (US) — QA for AI digital-human platform. CredibleMind (US) — QA, automation, content verification. PACT Studio (Canada) — Shopify & e-commerce QA. M2 Medical Spa (US) — Website, SEO, social media. Deluxe Holiday Homes (US & UAE) — Manual QA. Summit Medical Consultants (US) — Website & SEO. GenioFinder (US) — Website & SEO. Why clients stay: Most of mine stick around 6–24+ months. Not lock-in. Just don't need to explain the codebase twice. I catch what breaks before your users do. I build so the next feature doesn't need a rewrite. Broken AI feature? Full build needed? Tired of chasing QA separately from dev? Message me. I'll review your project for free. No pressure, no fluff. 🔥 What I Do 🔹 Full-Stack Web Development * React / Next.js / Node.js * PHP / Laravel / CodeIgniter * Shopify (Custom Themes + Liquid) * WordPress (Custom Themes, Plugins, WooCommerce) * REST APIs, Integrations, Headless CMS 🔹 Mobile App Development * Flutter hybrid apps * React Native apps * API integrations, push notifications, dashboards, real-time features 🔹 AI & Automation * AI chatbots * AI agents * Automation workflows (Make, Zapier) * AI API integrations (OpenAI, Gemini, Claude) 🔹 Manual & Automated QA * Functional, UI/UX, regression, cross-browser testing * Mobile app QA (Android, iOS) * Performance testing * Test cases, bug reporting, usability improvements ⭐ Why Clients Hire Me * Strong analytical + engineering mindset * Clean, scalable, maintainable code * Pixel-perfect UI implementation * Deep QA expertise (rare advantage for developers) * Clear communication & consistent availability * Long-term relationships (many clients work 6–24+ months with me) Full stack development, AI, Ai Developer, AI Integration, SaaS development, SaaS Developer, SaaS, Laravel, PHP, MySQL, PostgreSQL, Node.js, Express.js, React.js, Angular, Vue.js, JavaScript, TypeScript, HTML5, CSS3, SCSS, Bootstrap, Tailwind, REST API development, JSON, Axios, Git, GitHub, Bitbucket, CI/CD, AWS, Firebase, Google Cloud, Docker, Nginx, Apache, Shopify Liquid, WordPress, WooCommerce, Flutter, React Native mobile development, Android, iOS, Redux, Zustand, Next.js, API integration, performance optimization, website speed optimization, SEO friendly development, automation testing, manual QA testing, Jira, ClickUp, Trello, Postman, Stripe, PayPal, OAuth, JWT, microservices, SaaS development, CRM development.
