WHAT I BUILD FOR CLIENTS → Custom AI Software & Apps Full-stack AI applications built from scratch — frontend (Next.js / React), backend (FastAPI / Python), AI logic (OpenAI, Claude, RAG with pgvector or Pinecone), production deployment (GCP / AWS, Docker, CI/CD, Sentry). Recent build: a bilingual Arabic/English legal management platform with a RAG document drafter and WhatsApp client bot — drafting time cut from hours to minutes. → AI Integration Into Existing Software Connecting AI to the tools your business already runs on — CRMs, databases, internal apps, customer-facing platforms. Recent build: an AI underwriting engine for a real estate lender that replaced manual document review across the entire loan lifecycle. → n8n Workflow Automations Self-running pipelines that connect your CRM, email, WhatsApp, databases, and AI models into one system. Recent build: a multi-agent content pipeline that turns a single Telegram command into a published SEO article in 3–4 minutes — replacing ~15 hrs/week of manual work. → RAG-Powered Chatbots & AI Assistants Custom chatbots with real document grounding, conversation memory, and human handoff. Web, WhatsApp, Slack — wherever your customers are. WHY CLIENTS HIRE ME OVER THE NEXT FREELANCER ✓ Top Rated, 100% Job Success, 1,300+ hours on Upwork in this exact lane ✓ Production deployments — not prototypes.

I help startups and growing businesses build AI-powered products, workflow automation systems, and scalable SaaS platforms. Over the last 7+ years, I've designed, built, and deployed production systems ranging from AI agents and Voice AI applications to RAG platforms, business automation tools, and enterprise SaaS products. My experience spans AI architecture, backend engineering, cloud infrastructure, and full-stack development, allowing me to take products from concept to production without relying on multiple specialists. My focus goes beyond integrating AI into applications. I build the APIs, workflows, infrastructure, data pipelines, dashboards, and user experiences required to turn AI capabilities into reliable business products.

🌟🌟🌟🌟🌟 “Hasan didn’t just build a voice bot for us, he actually took time to understand our call flow and customers. The final system sounded natural, handled real conversations well, and reduced our team’s workload significantly.” Hey, I’m Hasan. I help businesses use Voice AI and call automation to handle calls, qualify leads, and book appointments automatically. I specialize in building natural-sounding voice bots and AI call agents that can talk to customers, ask the right questions, route calls, and trigger actions in your systems. Whether it’s inbound calls, outbound follow-ups, or missed call handling, I design voice workflows that work like a reliable virtual team member. Why people work with me: I’ve built and deployed production-ready voice AI agents for sales, support, and appointment booking I’ve worked with businesses in real estate, healthcare, recruitment, SaaS, and service-based industries I’ve helped teams reduce missed calls and manual call handling, saving hours of staff time every week I’ve implemented voice AI systems that increased lead capture and appointment rates How I work: First, I understand your current call flow, scripts, and where calls are being dropped or wasted. Then I build a working voice bot quickly so you can hear real conversations and give feedback. After that, I focus on reliability, call handling edge cases, logging, and easy maintenance. As your call volume grows, I keep optimizing the voice AI to improve accuracy and conversion. If your team is overwhelmed with calls or losing leads after hours, we should talk. Let’s start with a free strategy call. I’ll map out one voice AI automation that can realistically pay for itself within the next 30 days.

I help businesses automate lead generation, customer communication, and operations using AI voice agents, chatbots, CRM automation, and intelligent workflows. Over the last 5+ years, I’ve designed and deployed automation systems that connect AI, marketing funnels, CRM pipelines, and multi channel communication into one unified system. My work focuses on building scalable automation infrastructures that help companies respond to leads faster, qualify prospects automatically, and convert more conversations into booked appointments. Most businesses struggle because their CRM, automation tools, and AI integrations are built separately by different specialists. I solve that by designing the entire automation architecture end to end so everything works together seamlessly. If you are focused on growing your business, I can handle the technical system that powers it. 𝐓𝐡𝐞 𝐄𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞 𝐀𝐡𝐞𝐚𝐝 I build complete automation ecosystems that combine AI voice agents, conversational chatbots, CRM workflows, and marketing funnels so businesses can capture, qualify, and convert leads automatically.
