I’m a Full-Stack AI Developer who builds AI agents, RAG systems, intelligent chatbots, workflow automations, and SaaS MVPs. My work combines strong backend engineering with practical Generative AI solutions, allowing me to build fast, reliable, and production-ready systems that help businesses automate tasks, improve customer experiences, and scale their operations. 🔹 𝐀𝐈 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 & 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 I design and build advanced AI systems that fit naturally into real business workflows. My work includes creating AI agents capable of multi-step reasoning, structured decision-making, data extraction, tool calling, and memory-based interactions. I develop RAG systems using vector databases like Pinecone, FAISS, Weaviate, and Chroma so chatbots can respond accurately using your documents. I integrate LLMs such as OpenAI, Azure OpenAI, Claude, and open-source models depending on your performance, security, and budget needs. I also build voice AI agents using Deepgram, ElevenLabs, and Vapi, allowing businesses to automate bookings, customer support, and qualification calls. 🔹 𝐂𝐡𝐚𝐭𝐛𝐨𝐭𝐬 & 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 I build intelligent and context-aware chatbots for WhatsApp, SMS, email, and website chat widgets. I’ve developed WhatsApp chatbots for customer support, bookings, onboarding, and automated flows, and I also work with AI agent platforms like Botpress, VAPI, ElevenLabs, and more. My chatbots follow clear logic, handle unclear responses properly, and can seamlessly hand over to a human when needed. With experience across multiple frameworks, I can quickly learn and work with any new platform your project requires. 🔹 𝐅𝐮𝐥𝐥-𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 & 𝐒𝐚𝐚𝐒 𝐌𝐕𝐏𝐬 I build complete SaaS platforms using Python on the backend and React or Next.js on the frontend. This includes multi-tenant architectures, subscription systems, analytics dashboards, role-based access, onboarding flows, and modern UI experiences. My full-stack experience also extends to customizing the Chatwoot open-source customer support system, where I modify both frontend and backend features, integrate AI, enhance workflows, and deploy Chatwoot in production environments for clients. 🔹 𝐖𝐨𝐫𝐤𝐟𝐥𝐨𝐰 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 & 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧 I design systems that automate business operations end-to-end using tools like n8n, Zapier, custom APIs, and event-driven workflows. My automations handle lead qualification, CRM updates, appointment scheduling, ticket routing, document processing, and data validation. I frequently build systems that convert raw documents or forms into structured formats (JSON/SQL/SaaS) using AI and integrate them directly into CRMs like HubSpot, GoHighLevel, Salesforce, and others. 🔹 𝐖𝐞𝐛 𝐒𝐜𝐫𝐚𝐩𝐢𝐧𝐠 & 𝐃𝐚𝐭𝐚 𝐄𝐱𝐭𝐫𝐚𝐜𝐭𝐢𝐨𝐧 I create reliable and scalable scraping pipelines using Python with Playwright, Selenium, BeautifulSoup, and Requests. I extract clean, structured data even from modern dynamic sites and handle proxy rotation, CAPTCHA bypassing, and anti-bot systems. Extracted data is organized into spreadsheets, SQL databases, or delivered through APIs and automated schedules, depending on your needs. 🔹 𝐀𝐏𝐈 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 & 𝐒𝐲𝐬𝐭𝐞𝐦 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧𝐬 My backend work focuses on building secure, scalable API systems using FastAPI, Django REST Framework, and Flask. I develop authentication flows, dashboards, admin panels, payment integrations, microservices, and workflow engines. I work with PostgreSQL, MySQL, MongoDB, and Redis, ensuring clean architecture and strong performance across all parts of the system. ⭐ 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 𝐌𝐞: Clients appreciate my ability to blend strong AI engineering with stable full-stack development. I communicate clearly, deliver consistent progress, and write production-quality code that is scalable and maintainable. I focus on real business outcomes, not experiments, and I provide long-term support, documentation, and clean deployment processes. Whether you need an AI system, automation workflow, scraping pipeline, RAG assistant, or a full SaaS application, I can build it from start to finish.

✅ Top Rated | 1900+ Hours | 100% Job Success I build production grade SaaS platforms, AI systems, realtime applications, high concurrency backend infrastructure, and full stack mobile and web platforms. Most developers today can generate code with AI tools. Very few can architect systems that remain scalable, maintainable, and reliable once real users, payments, concurrency, and operational complexity enter the picture. That’s where I work best. My background is deeply rooted in backend engineering, distributed systems, and full stack architecture. AI has simply become another layer in the systems I design, not a replacement for engineering fundamentals. I work with startups and growing businesses that need more than just MVP development. They need stable foundations that can scale properly over time. I specialize in building: * Multi tenant SaaS platforms * AI orchestration and agentic workflows * Operational AI systems integrated into real business workflows * High concurrency backend infrastructure * Payment and subscription systems * Realtime dashboards and event driven systems * Queue based architectures and worker orchestration * Telephony and communication platforms * Customer engagement and loyalty systems * Workflow automation platforms * RBAC and enterprise permission systems * QR based tracking and attendance systems * API platforms and microservices architecture My AI experience goes beyond simple chatbot integrations and includes: * RAG pipelines and retrieval systems * Agentic workflows and AI orchestration * Tool execution pipelines * AI voice calling systems * Operational AI agents * Document intelligence and OCR pipelines * Permission aware retrieval systems * AI powered workflow automation * AI integrated backend infrastructure My primary stack includes: * Node.js, TypeScript, Python, PHP * React, Next.js, Angular * React Native, Expo, Flutter * FastAPI, Tornado, Django, Flask, Express, NestJS, Laravel, Symfony * PostgreSQL, MySQL, Redis, Supabase, MongoDB, DynamoDB * Docker, Kubernetes, AWS, GCP * OpenAI, Claude, LangChain, pgvector * Websockets, SSE, realtime systems * CI/CD pipelines and cloud native deployments * Large scale data extraction using Selenium, PlayWright, Requests, HTTPx, Requests * AI Chatbots, Slack bot, Telegram bot, Discord bot I regularly work with: * Queue systems and distributed workers * Event driven architectures * Payment infrastructure including Stripe * Backend optimization and scaling * Transactional consistency and idempotency * Observability, monitoring, and debugging * Realtime synchronization systems * Serverless and microservices environments Most of my engineering foundation was built long before the current AI wave, with a strong focus on backend systems, scalability, distributed infrastructure, and software architecture. I care heavily about: * Clean architecture * Performance under load * Execution reliability * Long term maintainability * Scalability and operational stability * Backend observability and debugging * Cost efficient infrastructure design * Transactional integrity and failure handling I don’t just build features. I help architect systems correctly so they survive real growth. If you’re building a serious product and need an engineer who can own complex technical problems independently, I’d be happy to discuss your project.
