Claude + Obsidian Terminal Connection
Riaz did a great job setting up Claude to connect with Obsidian and run through the terminal on a Windows machine, configuring the environment, connecting the correct vault, testing terminal commands, and verifying that Claude could create and modify notes inside Obsidian.
He handled the full setup remotely, communicated clearly, and confirmed everything was working before finishing. My cousin’s laptop had some TeamViewer issues at first, but Riaz stayed patient and found a workaround. Once connected, he completed the job quickly and professionally.

Workflow automation for scored survey with n8n, api, pdf generation and upsale
Great job, but a bit pricey. Helped get the project off the ground!

Video Automated Workflow Optimization
Riaz was a pleasure to work with on a complex n8n automation project. He took on an end-to-end YouTube Shorts pipeline (Google Drive, Whisper, ffmpeg, OpenAI, Sheets, YouTube upload) and brought real experience with large n8n systems, LLM JSON flows, and video processing. He was patient and professional through the remote-access setup and a few unavoidable hiccups, and he stuck with the project until it was in a good state. When the contract hit a budget snag, he handled it with integrity and kept working without running up the meter. Would recommend for n8n, automation, and video pipeline work.

Job Success
Gilgit, Pakistan - 10:36 am local time
My core work includes n8n workflows, GoHighLevel CRM automation, AI calling agents with Twilio and OpenAI, API integrations, webhooks, Google Sheets automation, and Python-based workflow logic. I also support reporting, dashboards, and data workflows when automation and analytics need to work together.
Clients hire me to build or fix workflows, connect tools, route leads correctly, automate follow-ups, organize data, and make day-to-day operations easier to run. My focus is production-ready implementation: clean logic, stable execution, error handling, testing, documentation, and handoff-friendly systems.
If you need an automation expert who can build, fix, and simplify workflows across multiple tools, I can help.
