I am Amrita Chandra Das, Founder and CEO of VideoCutStudio and a Camtasia specialist with 9+ years in professional video editing. I have spent that time turning raw screen recordings and messy source footage into course videos that people can actually learn from.
This blog is about the other half of my work: the AI, automation, and self-hosted infrastructure that sits underneath it.
The day job
My niche is narrow on purpose. eLearning, screencasts, online courses, educational content, and software tutorials. Not weddings, not brand films. The thing I am good at is making technical information easy to follow without overwhelming the person watching it.
I have been freelancing since 2017 and hold Top Rated Plus status on Upwork. The public numbers on my profile:
- 147+ jobs and 3,000+ hours logged
- 5.0 / 5.0 rating with a 100% Job Success Score
- $40,440 on a single long-term video production contract
- $63,000+ across selected featured projects
- Hundreds of eLearning videos delivered for one client alone
The endorsement clients leave most often is “committed to quality”, followed by “collaborative” and “reliable”. That order is roughly how I would rank my own priorities, which is reassuring.
The tools
Camtasia is the core: timeline editing, narration sync, screen recording cleanup, zooms and pans, cursor effects, callouts, captions. Around it sit Premiere Pro, After Effects, Audition, and Photoshop, plus Descript, Audiate, Audacity and iZotope RX for anything audio-heavy.
The skill that actually matters on large projects is not any one tool. It is consistency across a library of hundreds of videos: same structure, same visual language, same audio levels, same naming, lesson forty looking like lesson one.
Why a technology blog
Because the video work kept pulling me into the technology underneath it. Editing software tutorials means understanding the software. Delivering hundreds of videos means automating the parts that repeat. Wanting my own tools rather than another subscription means running my own servers.
So I ended up with a homelab. Docker containers on a VPS and on hardware at home, Home Assistant running the house, Cloudflare Tunnels providing access without opening a single port, local LLMs through Ollama, n8n stitching things together, and solar and battery monitoring feeding data into all of it.
None of that was a career plan. It was a series of specific problems, solved one at a time. This blog is where I write down what worked.
What I write about
- AI — generative AI, local LLMs and Ollama, prompt engineering, AI agents, and API integrations. Building workflows, not just using chatbots.
- Automation — n8n, APIs, and removing the repetitive parts of creative production.
- Self-Hosting — Linux, Docker, VPS administration, Cloudflare Tunnels, and owning your own infrastructure.
- Smart Home — Home Assistant, Raspberry Pi, IoT, networking, and solar and battery monitoring.
- Video — Camtasia, screencasting, course production, and where AI genuinely helps in an edit.
- Freelancing — finding clients, pricing, and running this as a business from Bangladesh.
The standard
If a post is about code, it contains code you can run. If it is about a setup, it is a setup I actually run. Where something has a limitation or a failure mode, the post says so, because a tutorial that only describes the happy path is how people end up with an exposed smart home.
Some posts are in English and some in Bengali. Freelancing advice in particular lands better in Bengali, because the people it is written for are here.
