🚀 I build practical AI automation tools that help businesses follow up with leads, qualify prospects, and hand warm conversations to human teams — using OpenAI, WhatsApp Business API, and clean full-stack web architecture. If you need a simple internal AI lead follow-up system, not an overbuilt CRM or complicated SaaS platform, I can help you design and build a scalable MVP that is easy to manage, easy to expand, and reliable enough for real client use. ✅ What I Can Help You Build I help businesses, agencies, and service providers build AI-powered internal tools such as: * AI lead follow-up systems for WhatsApp, web chat, or CRM pipelines * OpenAI-powered conversation flows that collect contact details and qualify leads * Multi-client admin panels with separate AI settings per client * FAQ, service, pricing, and company knowledge management tools * WhatsApp Business API integrations for automated conversations * Warm lead forwarding workflows to email, CRM, Telegram, Slack, or client inboxes * Simple management interfaces without unnecessary dashboards or bloated features * Scalable MVP foundations that can grow into a larger platform later My focus is not just “adding AI.” I build the full workflow around it: client setup, prompt/config management, conversation logic, data capture, lead qualification, API reliability, and clean handoff to the business owner or sales team. ⚙️ Tech Stack & Expertise Frontend: React, Next.js, TypeScript, Tailwind CSS, responsive admin interfaces Backend: Node.js, Express/NestJS, Python/FastAPI, REST APIs, webhook handling, background jobs AI: OpenAI API, GPT-based assistants, prompt configuration, structured outputs, lead qualification logic, AI guardrails, conversation memory WhatsApp & Messaging: WhatsApp Business API, Meta Cloud API, webhook-based message handling, conversation routing, lead notifications Database: PostgreSQL, Supabase, MySQL, MongoDB, Prisma, structured client configuration models Integrations: CRM APIs, email APIs, Telegram/Slack alerts, Zapier/Make-style automation, custom API workflows Architecture: Multi-client settings, clean database schema, scalable backend services, maintainable code structure, secure API design 🧩 Relevant Project Experience I am strongest in projects where AI needs to work inside a real business process, not just as a basic chatbot demo. Relevant systems I can help build include: * AI lead qualification assistants that ask the right questions, collect contact details, and score leads * WhatsApp-based customer follow-up flows for service businesses and agencies * Internal admin tools where each client has separate company info, FAQs, offers, pricing, and AI behavior * AI support/chat systems connected to custom knowledge bases * Lightweight automation platforms that start as an MVP and can expand later [Add real project proof here: AI chatbot, WhatsApp bot, CRM automation, internal admin tool, or OpenAI integration.] 🔐 Quality, Security & Scalability For this type of system, the most important part is the foundation. I usually structure the MVP around: * A clean client table with isolated configuration per client * Company info, services, pricing, FAQs, and AI behavior stored as editable data * Prompt templates that can be adjusted without changing code * WhatsApp webhook handling for inbound and outbound messages * OpenAI conversation logic with structured lead qualification * Warm lead forwarding when the AI detects buying intent * Admin-only access for managing clients and settings * Clear logging for conversations, errors, and lead handoffs * Modular code so future features can be added without rebuilding everything This keeps the first version simple, but prevents the project from becoming messy when new clients, channels, or automations are added later. 💬 How I Work With Clients I like to keep communication clear and practical. Before development, I define the MVP scope carefully so we do not waste budget on unnecessary CRM-style features. Then I usually break the project into clear phases: 1. Architecture and workflow planning 2. Client/admin setup 3. WhatsApp Business API connection 4. OpenAI conversation and qualification logic 5. Lead forwarding workflow 6. Testing, refinement, and deployment You get regular updates, clear technical explanations, and realistic advice about what should be built now versus what can wait for a later version. 📩 Let’s Talk Invite me to your job or send me a message if you need a developer who can build a simple, scalable AI lead follow-up tool with OpenAI, WhatsApp Business API, and a clean management interface. I’d be happy to review your workflow, suggest the best technical approach, and help turn it into a working MVP.

Throughout my career, I have been acknowledged as a solution-focused professional with the ability to design and develop innovative applications using advanced technologies. In my prior role as Full-stack Developer for LaunchCode, I collaborated closely with the application team to develop and implement 80+ full-stack web applications, ensuring optimal functionality, quality, and reliability.

My career as a web developer started 10+ years ago in which time it has proven that I am even better at coding and slicing. React and Material UI are the areas in which I excel so I became a Front-End developer but I am also familiar with back-end development languages like ExpressJS and PHP(Laravel). Also, I am ready to learn new ones and expand my current knowledge of the fore mentioned as needed to the point where it makes me do my job as a Front-End developer, faster, better and more efficiently. That is the way I dived into web programming in the first place and started to like it through the learning process. Specialties: - Front-End development (React, AngularJS, Vue.js, Material UI, Sass, Styled Component) - Back-End development (Laravel, ExpressJs, MySql, MongoDB), although I'm stronger on the front-end side - Web Standards - Usability & Accessibility
