I worked with Sami on the iSurvix SaaS project, and he did an excellent job. His expertise in AI and application development is very impressive. He successfully built a great app for isurvix.com and handled the entire project very professionally.
Sami managed all aspects of the work very well, from development to implementation. His communication was clear, and he made sure everything was delivered properly and on time.
I highly recommend Sami to anyone looking for a skilled AI and SaaS developer. Great experience working with him!

Product Manager
Sami Ullah was a truly dedicated and highly committed team member. He consistently put in his best effort, proactively contributed ideas, and always went the extra mile to ensure tasks were completed to a high standard. His coordination skills and ability to manage his own work independently made collaboration with him very smooth and reliable.
Unfortunately, after an internal restructuring, our schedules no longer aligned, which made it difficult to continue working together.
We sincerely wish Sami all the best for the future. We are confident that with his skills, professionalism, and positive attitude, he will continue to succeed and make a valuable contribution wherever he goes.

Job Success
Lahore, Pakistan - 1:20 am local time
I build AI voice agents, RAG chatbots, and n8n automations that answer calls, qualify leads, and remove manual work — for agencies, clinics, and SaaS teams. Top Rated, 100% Job Success, 26 projects delivered, 400+ hours on Upwork.
Most businesses I work with have the same two problems: leads come in and nobody answers fast enough, and the team is buried in copy-paste work between tools that don't talk to each other. I build the systems that fix both — and I build them so they keep running after I hand them over.
WHAT I BUILD
AI Voice Agents
Inbound and outbound calling agents on Vapi, Retell AI, and ElevenLabs with Twilio numbers. Call answering, lead qualification, appointment booking, and automatic CRM logging. Low-latency, natural conversation, with a clean handoff to a human when the call needs one.
RAG Chatbots & AI Support Agents
Chatbots trained on your own documents, help centre, or product catalogue using the OpenAI and Claude APIs with a vector database. Deployed to your website, WhatsApp, Instagram, or Slack. They answer from your content instead of inventing answers.
n8n & Make . com Workflow Automation
Production workflows connecting your CRM, email, forms, spreadsheets, and payment tools. Error handling, retries, and logging built in — so it doesn't fail silently at 2am and cost you a week of leads.
CRM & Lead Automation
GoHighLevel, HubSpot, and Airtable pipelines: lead capture, routing, scoring, follow-up sequences, and booking automation.
AI Integrations & Custom APIs
Connecting LLMs to internal tools where no off-the-shelf integration exists, using Python and REST APIs.

HOW I WORK
1. A short call to map your current process before I quote. If automation isn't the right answer, I'll tell you.
2. A written scope with a fixed deliverable list, so nothing drifts.
3. Build in staging, then test against your real data before anything goes live.
4. Handover with a Loom walkthrough and written documentation, so your team can run it without me.
5. 14 days of post-launch support included on every build.
WHY CLIENTS COME BACK
100% Job Success Score across 26 contracts and 400+ hours, with a 4.9 average rating. [X] clients have hired me for a second project. I reply to messages within [X] hours and my working day overlaps US mornings and full European hours.
PROBABLY NOT A FIT IF
You need a one-hour Zapier fix under $50, or you'd rather I "just make it work" without access to the accounts involved.
Tell me the process you want automated — or book a 30-minute consultation and I'll map it with you on the call and tell you what it will realistically take.
