You will get Pro AI phone agent to screen leads, route lines, and schedule
Project details
Get a 24/7 AI phone receptionist that answers, qualifies, routes, and books appointments across Google/Outlook calendars with real‑time call flows. Built with Conversational AI, ASR/TTS, and LLM tool‑calling, the agent screens leads, handles FAQs, and transfers to humans when needed for zero‑friction scheduling. Tech stack options include Retell/Vapi + Twilio with CRM integrations for HubSpot, Pipedrive, or GoHighLevel, optimized for low latency and clear handoffs. Ideal for clinics, home services, real estate, and SaaS demos where speed‑to‑lead and show‑up rates matter most. Deliverables include call script design, booking workflows, voicemail‑to‑text, analytics, and QA so every caller reaches the right person or an instant booking link. Keywords: AI voice agent, AI phone receptionist, call routing, appointment scheduling, calendar booking, Twilio, Retell AI, CRM integration, multilingual support, lead qualification, IVR.

About Sahil
AI + Full Stack Developer | Web, Mobile, CMS, DevOps
Ambala, India - 10:35 am local time
If you’re reading this, you’re probably not after another “developer.”
You’re after someone who can take your tech chaos and turn it into something that runs clean, fast, and smart — without you having to babysit it.
That’s what I do.
I design and build systems — not just pages, dashboards, or apps.
Systems that connect, communicate, and scale quietly in the background while you focus on the work that actually matters.
⚙️ What that means in practice
I work across the entire stack — front, back, AI, automation, mobile, web, cloud — everything in between.
Here’s what that looks like in real projects:
➥ Web apps that are smooth, scalable, and built on React, Next.js, Node, Express, or Laravel.
➥ Mobile apps in Flutter, Android, iOS, and PWA that feel native and sync perfectly with your backend.
➥ AI systems that do more than talk — OpenAI, LangChain, Gemini, custom fine-tuning, embeddings, vector search, and smart retrieval flows.
➥ Automations and workflows using Make, n8n, Zapier, or custom scripts — connecting CRMs, databases, APIs, and user events into one ecosystem.
➥ CMS/LMS setups that don’t collapse when traffic spikes — WordPress, Kajabi, Webflow, or custom headless builds.
➥ DevOps and Cloud architecture that keeps everything stable — Docker, CI/CD, AWS, Azure, GCP.
➥ Integrations and SDKs for custom logic, third-party APIs, and internal tools that need to work together seamlessly.
I build things that make other tools jealous.
🧠 The Stack I Know Cold
If it lives on the web, I’ve probably built with it.
➥ Frontend: React, Vue, Next.js, Tailwind, TypeScript, Redux.
➥ Backend: Node.js, Express, Laravel, PHP, MongoDB, PostgreSQL, MySQL.
➥ AI/ML: OpenAI API, Gemini, RAG pipelines, embeddings, fine-tuning, LangChain, Llama, HuggingFace.
➥ Automations: n8n, Make (Integromat), Zapier, custom Python workflows, CRON-based logic.
➥ Mobile: Flutter, Kotlin, Swift, React Native, PWAs, custom SDK integrations.
➥ DevOps: Docker, CI/CD, Nginx, GitHub Actions, Cloudflare, load balancing, server optimization.
➥ Platforms: WordPress, Webflow, Kajabi, Shopify, Framer, custom CMS/LMS builds.
➥ Integrations: Stripe, Firebase, Supabase, Airtable, Notion, Slack, HubSpot, Calendly, ConvertKit, Typeform, and dozens of APIs that don’t play nice out of the box — until I step in.
🔍 My Approach (how it actually feels to work with me)
➥ You won’t get buzzwords and vague promises — you’ll get clear logic and real communication.
➥ I’ll ask questions that make you rethink what you really need before I write a single line of code.
➥ Once we start, I map everything — from how data flows to how automation triggers.
➥ Then I build, test, and optimize like the system’s mine.
If it’s not fast, scalable, and beautifully predictable, it doesn’t leave my desk.
I’m the kind of dev who fixes your tech debt before it becomes a problem.
I document, automate, and make sure the next thing you build doesn’t break what we just built.
⚡ Why clients stick
Because I don’t just deliver features — I deliver clarity.
You’ll know what’s happening, what’s next, and how it impacts your system long-term.
There’s no “vanishing dev” drama. No “it works on my machine” nonsense.
✅ 11+ years in software & system architecture
✅ 20+ full-scale builds — AI products, automation pipelines, mobile & web apps
✅ 90%+ Upwork success rate and $100K+ earned
✅ Known for clean communication, fast iteration, and scalable delivery
I’ve worked with creators, SaaS founders, agencies, and enterprise teams — and the pattern is always the same:
They come in with a mess.
They leave with a system.
🧩 What I love building
→ Full-stack AI products — with chat, context, and custom logic
→ Workflow automation that replaces 3 employees worth of manual effort
→ Smart web dashboards that make data feel alive
→ Mobile apps that feel native and sync perfectly
→ CMS/LMS platforms that grow with your users
→ API-driven SaaS tools that just work
→ Custom DevOps setups that deploy themselves when you blink
🚀 Bottom line
I’m not here to overcomplicate your stack.
I’m here to build things that make sense, automate what’s repeatable, and help your business scale without duct tape.
If your tech stack feels cluttered, your workflows feel too manual, or your systems don’t talk — I can fix that.
If you’re ready to connect everything — frontend, backend, AI, mobile, automation, and analytics — I can build that.
You focus on the brand.
I’ll handle the logic, the load, and the long game.
Let’s make your tech work smarter.
Not harder.
Not later.
Now.
