Hire an IoT developer in India
I build complete IoT systems: the sensor node, the firmware running on it, the cloud backend it reports to, and the dashboard your team watches. One person, one point of contact, no integration gap between vendors.
That last part is the problem I solve. IoT projects fail at the seam: your firmware contractor says the node sends the data, your web agency says nothing arrives, and you arbitrate between them without the background to judge who is right.
Systems I've built end to end
Smart Well Management monitors groundwater levels and quality for city planners, with map-based dashboards and predictive alerts. Smart Waste Management uses 8051 and ESP32 nodes to report bin fill levels to a live map with automated overflow emails. A dual-fingerprint attendance system pairs ESP32 biometric capture with a web dashboard and automated reporting.
For each one I chose the sensors, wrote the firmware, designed the database, built the interface, and deployed it. These run in the field, past the demo stage.
- ESP32, ESP8266, Arduino and 8051 firmware
- Sensor selection, interfacing and calibration
- Sync to Supabase, Postgres or a REST API that survives dropouts
- Live dashboards with maps, history and threshold alerts
- Email and push notification pipelines for critical events
Where IoT projects break
Teams leave connectivity until last, so the system works on a desk and fails in the field. They skip planning for a node that loses power or network for six hours. They let data land with no schema discipline, and six months later nobody can query it. Then someone bolts a dashboard onto a data model they had no hand in designing.
All four are seam problems, which is why I take the whole stack instead of one layer.
Working across India and remotely
I live in Goa and work remote across India and abroad. I prototype hardware here, and travel for deployment and commissioning when a project needs it. For clients outside India, IST overlaps with Europe and the Gulf in my morning, and US Eastern in my evening.
What you get
One person covers firmware, backend, frontend, and deployment
On a connected-hardware project, most clients hire a firmware contractor and a separate web agency, then carry the integration risk themselves. I built Smart Well Management and Smart Waste Management alone: sensor selection, ESP32 firmware, database, dashboard, deployment.
Eleven shipped projects with live demos and public source code
Most portfolios show mockups. Nine of the eleven projects here link to a working deployment, a public GitHub repository, or both.
Five hackathon podium finishes, including Smart India Hackathon
Judges at five events scored these builds against other teams under a deadline. That carries more weight than my own claim about how fast I work.
India-based rates, timezone that overlaps Europe and the Gulf
IST (UTC+5:30) gives you a full morning overlap with Europe and the Middle East, and an evening overlap with US Eastern. You pay Indian rates without routing the work through an intermediary.
You own the code from day one
Your code sits in your repository and deploys to your infrastructure, with setup documentation at handover. You never rent a platform from me.
Relevant services
IoT & Connected Hardware
Sensor-to-dashboard systems built end to end: the board, the firmware, the cloud sync, and the screen your team watches it on.
Full-Stack Web Applications
Production web apps with working auth, roles, and data behind them, built for your case rather than dropped onto a template.
Questions
Can you do both the hardware and the software?
Yes, and it is the specific reason to hire me over two separate vendors. I select sensors, write the ESP32 or Arduino firmware, design the database, build the dashboard, and deploy it. When a number on screen looks wrong, one person answers for it.
How long does an IoT project take?
Four to eight weeks, longer than a pure web project because I have to source the hardware, wire it, and test it in place. You get a specific timeline in the written scope and see working progress each week.
Do I need to buy the hardware myself?
Either way works. I can specify what to buy and you procure it, or I source it and bill it through at cost. Pinning the parts down upfront keeps you from discovering mid-build that a sensor cannot do what the project needs.
Tell me what you're trying to build
A couple of sentences is enough. I read each message myself and reply within about a day, including a straight no when the work is a poor fit.
