Everything we offer — from full product engineering to the individual building blocks: boards, firmware, applications, websites and advice. Seven practice areas, one team, one engineering discipline.
The stack · hardware to cloud
No handoffs, no “that’s the firmware guy’s problem.” The engineers who route the Gerbers write the RTOS tasks, define the protocol frames, and ship the app that renders them.
Schematics, PCB Gerbers, and bench bring-up with the scope attached — we verify the silicon before trusting the label.
Bit-banged drivers and peripheral bring-up verified against the datasheet, not the vendor example.
FreeRTOS task budgets, ISR discipline, and queues that don't drop frames under load.
Deterministic comms on dirty wires, with defined failure states.
Operator consoles, executive dashboards, websites and Flutter apps carried all the way to the Play Store.
Brokers, backends, hosting and fleet dashboards — Firebase where it fits, self-hosted where it doesn't.
01 · Automation & Monitoring
We instrument real operations — production lines, warehouses, growing systems — with sensors, controllers and dashboards. The result is live visibility, alerting and the efficiency metrics that drive decisions.
Sensor networks and dashboards that track utilisation, throughput and environmental conditions across industrial floors.
Closed-loop control of nutrient dosing, pH and circulation, paired with a monitoring app for growers.
Monitoring for factories and manufacturing plants — machine and process parameters captured live, with alerting and automatic report generation.
Tailored greenhouse automation that monitors and controls climate and growing parameters for protected cultivation.
TDR-sensor-based soil monitoring capturing NPK, soil temperature and humidity, paired with a companion mobile application.
Premises monitoring covering staff attendance, entry/exit movement and guest visit logging.
02 · Product Development
Bring us a product idea and we carry it through requirements, electronics design, firmware, prototyping and pilot production. These are some of the products we have engineered.
A traffic junction controller that adapts signal phases to live traffic density instead of fixed timers.
Touch-free dispensing product developed from sensor selection through firmware and production-ready electronics.
A grower-focused automation product handling dosing, circulation and environment control for soilless farming.
Single-phase and three-phase battery regeneration and discharge equipment with on-machine LCD interfaces.
03 · Consultation
Not every engagement starts with a build. We advise teams on new product development, component selection, architecture, certification-aware design and manufacturing readiness — and we review existing designs that need a second pair of eyes.
Feasibility studies, architecture definition, BOM and cost guidance, and development roadmaps for new electronic products.
Design reviews, debugging support, firmware architecture and platform selection for in-flight embedded projects.
04 · Embedded Mobile Apps
Hardware is only half the product. We build the companion mobile applications that configure, monitor and report on embedded systems — designed together with the firmware, so the whole product works as one.
Live gas-level monitoring app paired with wireless sensor hardware and a data-logging web API.
Operator app for hydrogen-based engine decarbonisation machines — session control, status and service records.
Battery test, regeneration tracking and health reporting companion to the regeneration machines.
Attendance with entry/exit tracking and guest visit management for offices and facilities.
Factory and manufacturing plant monitoring with configurable alerts and automatic report generation.
Companion app for the TDR-based soil monitoring system — live NPK, soil temperature and humidity readings in the field.
Grower dashboard for hydroponic systems — live readings, dosing history and yield records.
Agriculture product suite built for Rekhan Agro — field monitoring and farm record applications.
05 · Mobile & Desktop Software
Beyond device companions, we build full mobile and desktop applications: membership and booking platforms, manufacturing utilities and tools that provision and maintain fleets of microcontrollers in the field.
A membership platform for an exclusive personal-training studio: a member app for sessions, body-composition tracking and subscriptions, with a coach and ops console behind it.
Desktop and cloud tooling to flash, configure and update microcontrollers over the air at fleet scale.
06 · Websites & Web Apps
Most small-business websites go stale because every change costs money. We build them the other way round: the site is fast and static where it matters, its content lives in Firestore, and the owner gets a branded Android app to change products, photographs, PDFs and copy whenever they like. sairatna.in runs exactly this way.
Multi-page responsive sites on Firebase Hosting — custom domain, automatic SSL, per-route SEO metadata, sitemap and analytics.
Your content in Firestore and a companion Android app to edit it. Add a product, swap a photo, rewrite the homepage headline — the live site picks it up on the next load.
Quote forms that record every enquiry in Firestore and hand the customer straight to WhatsApp, pre-filled — so nothing is lost between the website and the conversation.
Browser dashboards over live plant data — OEE, downtime, utilities and one-click PDF reporting, as built for the Plastech command center.
Firebase Hosting, DNS and SSL setup, cache headers, security rules and the ongoing care that keeps a site healthy after launch.
Every site we build ships with a branded admin app for your phone. Prices, photos, opening hours, the headline on your home page — you change them yourself, in seconds, and the site updates for every visitor. No support ticket, no hourly rate, no waiting on us. The screens below are real: a headline being retyped on a phone, landing on this very site.
Most agencies bill for every text tweak. Yours are free because you make them — the dashboard is part of the build, not a subscription.
Your edit reaches visitors immediately. Nothing is rebuilt or redeployed, and nothing waits in a queue behind someone else's job.
Your Google account, your Firebase project, your domain. If you ever stop working with us, the site and the dashboard keep running.
07 · PCB Development
We design boards that ship: multilayer controllers, low-power wireless sensor nodes and connectivity boards, taken through schematic capture, layout, prototype bring-up and fabrication handoff. A selection of boards we have designed:
Main controller board for the DeCarb engine cleaning platform — power control, sensing and HMI interfaces.
Compact sensing board feeding live process data back to the DeCarb motherboard.
General-purpose IoT controller combining ESP32 Wi-Fi/BLE with cellular GSM fallback for remote sites.
Dosing and environment control board for hydroponic automation systems.
Control electronics for an electronic mosquito trap product.
Electronics developed for PMPML transit applications.
Family of low-power sensor node designs for industrial and agricultural monitoring networks.
Describe the product — we’ll map the path from silicon to cloud.
