Freelance — booked through Fiverr
Hire me
I take on a small number of freelance projects alongside my automation work. Each service below is booked through Fiverr, where the scope, current price and delivery time are kept up to date — and where the work is covered by their protections rather than a handshake.
If your project doesn't fit any of these, email me at me@ohidur.com and describe it. I usually reply within a day.
Services
Most requested
MCP server development
A Model Context Protocol server that lets Claude Code, Cursor and other AI agents read from and act on your own systems — your API, your database, your files — instead of guessing.
What you get
- Tools and resources designed around your actual workflows
- Authentication and scoping so an agent only reaches what it should
- Works with Claude Code, Claude Desktop, Cursor and any MCP client
- Runs where you want it: local stdio, or hosted over HTTP
- Setup docs your team can follow without me
RAG chatbot on your own documents
A retrieval-augmented chatbot that answers from your documentation, policies or product data, with citations back to the source. Self-hosted where you need the documents to stay on your own infrastructure.
- Ingestion for PDFs, Office documents, Markdown and web pages
- Vector search tuned on your content, not a generic default
- Answers cite the source document so staff can verify them
- Self-hosted or cloud, whichever your data policy requires
- An embeddable widget, or an API your own frontend calls
ESP32 & PLC monitoring dashboards
Live monitoring for machines that are already on your floor. Firmware on the ESP32, a link to your PLC over Modbus, CAN or RS-485, and a dashboard that shows the line as it runs.
- ESP32 / ESP8266 firmware, written for continuous duty
- Modbus RTU and TCP, CAN and RS-485 integration
- Live dashboard with history, thresholds and alerts
- MQTT or HTTP telemetry into a database you control
- Wiring notes and a commissioning checklist
VPS deployment with Docker
Your application running on your own server, containerised, behind HTTPS, with a deploy you can run again next month without remembering anything.
- Dockerfile and Compose setup for your stack
- Nginx or Caddy reverse proxy with automatic TLS renewal
- Server hardening: firewall, SSH keys, unattended upgrades
- Backups and a restore you have actually tested
- CI that redeploys on push, plus a runbook for the rest
Live 1-on-1 Claude training
A live session on your own work, not a recorded course. We take the tasks that eat your week and automate them while you watch, so you can repeat it after I log off.
- Screen-shared session at your pace, recorded for you to keep
- Built around your real tasks and your real files
- Prompting and context habits that survive past the call
- Claude Code, Projects and MCP set up on your machine
- A written summary of what we built and how to extend it
Before you book
Most of what I do is written up in the writing — deployment, Docker, embedded work and the rest.
It is a fair sample of how I approach a problem, and reading a post or two is the cheapest way to decide whether we'd work well together.
