Full-Stack & IoT Developer
About
Most products that touch the physical world need firmware, a backend, and an interface. I cover all three, which is why people call.
I'm Moses Rodrigues, a developer in Goa, India. I started on microcontrollers, where you can lose an hour to a loose jumper wire, then grew outward into the web and mobile apps that sit on top of them.
The overlap is what clients pay me for. Plenty of developers can build you a Next.js dashboard. Fewer can also pick the sensor, write the ESP32 firmware feeding it, and answer for a number on screen that looks wrong. You get one person to call instead of two vendors pointing at each other.
I have shipped eleven projects this way: groundwater monitoring for city planners, blood-bank coordination for hospitals, crop disease spotted from a phone camera. Along the way I took five hackathon podium finishes, Smart India Hackathon among them. I'm in my final year of a B.E. in Electronics & Computer Engineering, and take client work alongside it.
I wire up ESP32, ESP8266, and Arduino boards, pull clean sensor data off them, and push it to a cloud database you can query.
I build web and mobile apps with Next.js, React, React Native, Node.js, and Supabase, including auth, dashboards, and payments.
Hackathons taught me to go from empty repo to working demo in 36 hours. On client work that habit turns into weekly builds you can click through.
What I build
Most of my work lands in one of these, often two in the same project. Each one has shipped code behind it, so you can check the claim.
Sensor-to-dashboard systems built end to end: the board, the firmware, the cloud sync, and the screen your team watches it on.
Shipped on Smart Well Management · Smart Waste Management · Smart Fingerprint Attendance
Production web apps with working auth, roles, and data behind them, built for your case rather than dropped onto a template.
Shipped on BloodConnect · WellnessAI · ArchBlizz
LLM and computer-vision features built into your product where they do a job, with cost controls and fallbacks that hold when a model fails.
Shipped on CropGuard · LogExplain · ArchBlizz
One React Native codebase, Android and iOS, talking to the same backend as your web app.

Three I would show a new client first. Each went the whole way, from hardware through backend and interface to deployment, and most have a live demo you can open now.
2025Smart well management with EcoWell AI: real-time monitoring, secure access, and interactive maps for groundwater insights. Built with Next.js and Supabase.
2025A web and mobile app that lets farmers identify crop diseases from a phone camera, then tells them how to treat it in plain, farmer-friendly language.
2024A dual biometric attendance system with hardware integration, a web interface, and automated email reporting, reachable over the local network or a phone.
How I work
Hiring someone in another country comes down to trust. This is how a project runs from the first message to handover.
A 30-minute call or a long email thread, whichever you prefer. I ask what the system has to do, who uses it, and what you already have running.
You get a written breakdown of what I will build, what falls outside the scope, the timeline, and a fixed price or rate. No surprise line items later.
You get something clickable each week and a short note on what changed, so you can steer the build while it still costs nothing to change.
Source code in your repo, deployed and running, with setup docs. I fix bugs free for two weeks after launch.
Recognition
Five podium finishes at national and regional hackathons. Judges scored these builds against other teams, under a deadline, in front of a room.

Timeline
Where I have worked and what I did there: Android systems at The Grit City, web at All Right Systems, plus earlier frontend, QA, and AI roles.
The Grit City · Internship
Building DroidSwarm, a remotely managed Android device cluster with zero-touch provisioning that supports devices back to Android 13, and orchestrating automated test runs across multiple Android versions.
All Right Systems · Full-time
Building a restaurant management platform that turns daily operational data into profitability-focused insights, including AI analytics that benchmark a venue against others in its category.
EPICFORCE.AI · Internship
Built a custom WordPress plugin extending wp-admin with 10+ modules, including Decision Academy, Exercise Library, Reports, Automations, and Integrations, plus user progress tracking, notifications, and journey pages.
BitMento™ · Internship
Tested BitMento's EdTech platform and reported UI/UX issues with detailed reproduction steps, working remotely with the product team to improve usability and feature reliability.
PTWO Technologies · Internship
Developed responsive React interfaces from Figma designs, improving maintainability through reusable, component-based architecture.
BharatCares™ · Internship
Applied machine learning and NLP to text analysis, and built conversational AI flows in Botpress with intent recognition and response handling.
FAQ
These come from clients weighing up whether to hire someone remote. Short answers, no sales language.
Yes. I work remotely with clients in the US, UK, UAE, Singapore, Australia, Canada, and across Europe. I sit in India Standard Time (UTC+5:30), which gives you a morning overlap with Europe and the Gulf, and an evening overlap with US East Coast. For US Pacific clients I take calls early in my morning and keep the rest async.
Goa, India. I work remote, including with teams in Noida. I travel within India for hardware installs and on-site commissioning when a project needs it.
Four kinds: IoT and connected hardware (ESP32, ESP8266, Arduino, sensors, cloud dashboards), full-stack web apps (Next.js, React, TypeScript, Supabase), AI features inside existing products (LLM chat, image classification, OCR), and cross-platform mobile apps in React Native. Projects that mix hardware and software are the ones I most enjoy.
Three ways, depending on how well-defined the work is. A fixed price for a scoped build, a monthly retainer for ongoing work, or an hourly rate for consulting and short fixes. I quote after we scope the work, because a number without a scope is a guess.
A focused web app or dashboard lands in two to five weeks. IoT builds run four to eight weeks, because I have to source the hardware and test it in place. You get a specific timeline in the written scope and see working progress each week.
Yes, and that is the main reason to hire me. On Smart Well Management and Smart Waste Management I picked the sensors, wrote the ESP32 firmware, designed the database, built the Next.js dashboard, and deployed it. You skip the firmware contractor and web agency who blame each other when the numbers look wrong.
You do. Your code sits in your repository from the start, or I transfer it at handover with setup documentation and credentials. You rent no hosting from me.
I'm a Web Developer at All Right Systems, a US company, working remotely, and an AI & Android Systems Engineering Intern at The Grit City, where I'm building DroidSwarm, a remotely managed Android device cluster. I take freelance projects alongside both. Earlier roles: core developer at EPICFORCE.AI, QA tester at BitMento, frontend developer at PTWO Technologies, and AI intern at BharatCares. I'm in my final year of a B.E. in Electronics & Computer Engineering at Agnel Institute of Technology and Design, Goa, graduating in 2027.

A couple of sentences is enough to start. I read each message myself and reply within about a day, including a straight no when the work is a poor fit.
