Project Overview
Sādu is an environmental and social governance (ESG) solution designed to help companies of all sizes take their first steps toward sustainability. By connecting individual well-being with global impact, Sādu empowers organizations to turn healthy habits into reforestation and sustainability initiatives.
Sally Engineering was initially contracted to develop the iOS mobile application within three months—a challenge we successfully met. Due to our technical execution and collaborative approach, the partnership quickly expanded to include Android development and additional feature implementations.
Project Details
Sally Engineering served as Sādu’s full-cycle technical partner—covering mobile, backend, cloud, and blockchain development. We helped transform the initial concept into a production-ready ESG platform, continuously evolving the product with new features, integrations, and optimizations across multiple releases.
Our scope included building cross-platform mobile apps, designing backend architecture, integrating wearable tech, and implementing smart contract functionality. We worked closely with the founding team in an agile, collaborative environment to deliver fast and flexibly.
Key technical highlights:
- React Native for cross-platform mobile development (iOS & Android)
- Spring Boot backend architecture
- AWS infrastructure using RDS, S3, and Elastic Beanstalk
- Fitness device integrations for real-time step/activity tracking
- Gamified impact tracking tied to environmental rewards
- ERC-721 smart contract integration for NFT-based recognition


Result Driven
Since its launch in June 2021, the Sādu platform evolved rapidly, with live deployments on both iOS and Android. Users were able to track physical activity and translate it into measurable environmental impact - like planting trees - creating a meaningful link between personal wellness and ESG responsibility.
Sally Engineering became the end-to-end tech partner behind Sādu’s product. We delivered the mobile applications on time and remained actively involved post-launch - building features, maintaining performance, and supporting the product’s growth.
Our team prioritized open communication, transparency, and agility. We worked closely with the Sādu founding team, contributing beyond code - from product strategy to backend architecture - helping shape the platform during its most critical growth phase.
