The stack in detail

What we use, and why we use it

Programming Languages

Python
Powers our data analytics, automation scripts, backend services, and AI integration — enabling rapid development with maximum clarity and scalability.
Embedded C
The backbone of our firmware development — allowing precise control over microcontrollers and edge devices with low memory footprint and high real-time performance.
C#
Used in specialized projects for desktop-based control panels and industrial system interfaces, offering rich UI/UX and seamless Windows integration.

Frameworks

Django
Our preferred framework for large-scale, secure, and maintainable web applications — used in enterprise-grade dashboards, asset tracking systems, and user management portals.
Flask
Lightweight and flexible, ideal for building fast microservices, APIs, and internal tools that power modular components of our automation architecture.

Web Technologies

HTML5, CSS3 & JavaScript
We craft intuitive and responsive interfaces using HTML5, CSS3, and modern JavaScript practices, ensuring accessibility, performance, and a smooth user experience across devices.
jQuery
Used in legacy system integrations and rapid prototyping, enabling fast interactions and compatibility with diverse platforms.

Frontend Technologies

Angular
We use Angular for enterprise applications that require structured codebases, form-heavy workflows, and multi-role access management — ideal for admin portals and operational dashboards.
React.js
Perfect for building dynamic, real-time, and highly responsive frontends — powering our IoT control panels, live data visualization, and modular component libraries.

Databases

MySQL
Used in systems that require reliability and structured transactional data, such as user management, inventory, and configuration records.
MongoDB
Our go-to NoSQL database for flexible, high-speed storage of sensor data, logs, and document-based configurations.
PostgreSQL
Employed when advanced queries, GIS support, and relational integrity are required — suitable for critical analytics platforms and data warehouses.

Cloud Infrastructure

Amazon Web Services (AWS)
Our primary cloud environment for deploying enterprise-grade applications and IoT platforms. We leverage services like IoT Core, EC2, Lambda, S3, and RDS to build secure, scalable, and highly available systems — supporting everything from real-time telemetry to cloud-based control panels. AWS also supports our DevOps pipelines, automated deployments, and global application delivery.
Google Cloud Platform (GCP)
Deployed in projects requiring advanced data processing, AI model hosting, and seamless integration with Google’s ecosystem. GCP enables us to run machine learning pipelines, serve web apps, and analyze massive datasets efficiently through BigQuery, Cloud Functions, and App Engine.
Firebase Realtime Database
Ideal for applications that demand instantaneous, bi-directional data syncing, especially mobile and IoT dashboards. Firebase allows us to build real-time user interfaces with secure, low-latency cloud storage and effortless offline capabilities — critical for smart control systems and live monitoring environments.

Communication Protocols

MQTT
Lightweight and ideal for real-time IoT communication with minimal overhead — perfect for remote sensor and device networks.
LoRaWAN
Enables low-power, long-range communication in rural or factory-floor environments — critical for smart energy and logistics solutions.
Wi-Fi, Bluetooth, IR, RF
Provide reliable short- and medium-range communication depending on the device form factor and data throughput requirements.
UART, SPI, I2C
Our firmware leverages these hardware-level protocols for seamless device-to-device communication.
Modbus
Ensures compatibility with industrial PLCs and legacy automation systems — enabling integration with existing SCADA infrastructures.

Web Services & APIs

RESTful APIs
Serve as the foundation for secure and structured communication between devices, mobile apps, and cloud systems.
WebSocket
Power real-time updates and bidirectional communication — used extensively in control panels, alert systems, and live dashboards.
OTA (Over-the-Air) Updates
Our embedded devices are capable of remote firmware upgrades — ensuring devices remain secure, up-to-date, and future-proof without on-site intervention.
