ID Plans (USA)

Industry

Commercial Real Estate Software

Challenge

The client needed a reliable engineering partner capable of building new applications while maintaining and improving several existing systems. They required a team that could integrate seamlessly with their workflows, ship production-level features, and handle complex front-end and back-end work across multiple technologies.

Built

Two new production applications built end-to-end. Enhancements, maintenance, and refactoring of multiple existing systems. Advanced front-end and back-end features, including interactive UI components, high-performance rendering (HTML5 Canvas), and API integrations. Continuous collaboration with their internal engineering team, including code reviews, architecture improvements, and long-term support.

Tech Stack

React · NestJS · HTML5 Canvas · Ember.js · Node.js · TypeScript · Docker

Results

Development velocity increased thanks to consistent delivery and cross-team collaboration. Legacy projects received stability improvements, refactoring, and long-term maintenance support. New applications were shipped to production on time and integrated smoothly with existing internal systems. The partnership allowed the client's internal team to focus on strategic product decisions while Madow Tech handled critical engineering execution.

"Madow Tech became a trusted extension of our engineering team. They consistently delivered high-quality work across multiple projects and technologies while respecting all security and confidentiality requirements." - Axel, CTO at ID Plans

Feldico (Argentina)

Industry

Agritech / Marketplace Platforms

Challenge

The client needed a unified digital platform capable of organizing the fragmented rural-contractor market in Argentina. They were struggling with informal hiring processes, unreliable communication channels, lack of pricing transparency, and no standardized way to manage contracts, machine data, or logistics.

Built

A full end-to-end platform that includes: Web marketplace for contractors and producers, Contractor listings with machines, activity posts, roadmaps, and availability, Standardized digital contracting workflow, Geospatial search (PostGIS) for matching by region and date, Admin tools, email engine, and automated workflows, SSR frontend for high performance and SEO, Image/file processing pipeline connected to object storage, APIs for future integrations such as telematics, insurance, and fuel partners.

Tech Stack

Ember.js + FastBoot SSR · Node.js (Kurier.js / NestJS migration) · PostgreSQL + PostGIS · Elasticsearch · Docker + Reverse Proxy + Object Storage

Results

The platform significantly reduced manual coordination between producers and contractors thanks to automated matching, roadmaps, and structured listings. Contract management became far more consistent by moving from informal agreements to standardized digital workflows. The client reported strong improvements in user satisfaction because availability, pricing rules, and contract conditions became transparent. Deployment and development cycles became more predictable thanks to Madow Tech's CI/CD setup and containerized infrastructure.

"Madow Tech has been instrumental in turning Feldico from an idea into a scalable platform. Their ability to combine solid engineering with real-world understanding of agriculture allowed us to build a product our users can trust." - Marcelo 'Mars' Mira, Founder & CTO at Feldico
