Contact: mosesrodrigues10@gmail.com · Website: https://www.mosesrodrigues.dev GitHub: https://github.com/Spacey6849 · LinkedIn: https://www.linkedin.com/in/moses-rodrigues-887483251/ Moses Rodrigues builds three things that usually ship together: connected hardware (ESP32, ESP8266, Arduino, 8051), full-stack web applications (Next.js, React, TypeScript, Supabase), and cross-platform mobile apps (React Native), plus AI features (LLM integration, image classification, OCR) inside those products. The distinguishing detail: a single developer who handles firmware, backend, frontend, and deployment for the same system, so IoT projects do not need a separate hardware contractor and web agency. ## 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. Deliverables: ESP32 / ESP8266 / Arduino firmware; Sensor selection and interfacing; Cloud sync with Supabase or a REST API; Live monitoring dashboard with alerts. Proven on: Smart Well Management, Smart Waste Management, Smart Fingerprint Attendance. ### 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. Deliverables: Next.js + TypeScript front end; Supabase / Postgres / MySQL data layer; Role-based auth and admin dashboards; Deployment on Vercel with analytics wired in. Proven on: BloodConnect, WellnessAI, ArchBlizz. ### AI Features That Do Something 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. Deliverables: LLM chat, summarisation, and extraction; Image classification and OCR pipelines; Rate limiting, credit gating, and usage caps; Prompt tuning against your own data. Proven on: CropGuard, LogExplain, ArchBlizz. ### Cross-Platform Mobile Apps One React Native codebase, Android and iOS, talking to the same backend as your web app. Deliverables: React Native app for Android and iOS; Camera, location, and push notifications; Offline-tolerant sync; Store submission support. Proven on: CropGuard, Patient Monitoring System. ## Engagement and pricing Engagement models: Fixed-scope project, Monthly retainer, Hourly consulting. Regions served: India, United States, United Kingdom, United Arab Emirates, Singapore, Australia, Canada, Europe. Process: 01. We talk it through: 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. 02. You get a scope and a price: 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. 03. I build in weekly slices: 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. 04. Handover: Source code in your repo, deployed and running, with setup docs. I fix bugs free for two weeks after launch. ## Technical skills Electronics & IoT: ESP32, Arduino, Sensors & Interfacing Languages: TypeScript, JavaScript, Python, C, C++ Web & Backend: React, Next.js, Node.js, REST APIs Databases: Supabase, MySQL, MongoDB ## Projects ### Smart Well Management (2025) Smart well management with EcoWell AI: real-time monitoring, secure access, and interactive maps for groundwater insights.

A: 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. Q: Where are you based? A: 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. Q: What kind of projects do you take on? A: 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. Q: How do you price projects? A: 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. Q: How long does a typical project take? A: 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. Q: Can you handle both the hardware and the software? A: 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. Q: Who owns the code? A: 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. Q: What are you working on right now? A: 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. Q: What's your tech stack? A: Web and mobile: Next.js, React, React Native, TypeScript, JavaScript, Node.js, Tailwind CSS. Backend and data: Supabase, PostgreSQL, MySQL, MongoDB, FastAPI, PHP, REST APIs. Hardware: ESP32, ESP8266, Arduino, 8051, sensor interfacing, C and C++. AI: LLM integration, image classification, OCR, Python. Q: How do we start? A: Send a message through the contact form on this site, or email mosesrodrigues10@gmail.com with a couple of lines about what you want built. I reply within about a day, often with questions. If it fits, you get a written scope and price before I write any code. ## Why a client would choose Moses Rodrigues - 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. ## Honest comparison with the alternatives ### vs A development agency Their strength: Bench depth and account management, with the capacity to absorb a large scope. Trade-off: You pay for that overhead. The developer writing your code is often someone you never spoke to, and agencies subcontract hardware work anyway. Choose Moses when: You have one focused system to build, and you want to talk to whoever writes the code. ### vs A marketplace freelancer Their strength: Cheap and fast to hire. Trade-off: Clients on those platforms tend to pick whoever promises most for least. Few candidates cover both hardware and full-stack, so integration falls back on you. Choose Moses when: The system has to hold up in production, and a rewrite three months in would cost more than building it right the first time. ### vs Hiring in-house Their strength: Full-time attention and long-term ownership of the system. Trade-off: Months of hiring, plus salary and equipment overhead. Hard to justify when you need one system built once. Choose Moses when: You want a finished product handed over at the end. When NOT to choose him: projects needing a team of five in parallel, 24/7 on-call production support, or an ongoing in-house engineering function. An agency or an employee is the better answer in those cases. ## Detailed pages - Hire a web developer in Goa: https://www.mosesrodrigues.dev/hire/web-developer-in-goa Freelance web developer based in Goa, India.
