A technical studio specializing in custom software development. We work with few clients, on projects where depth matters more than speed.
Aastera Technology provides software development and maintenance services to a small number of selected clients. We do not pursue volume. We pursue depth — in every project, every technical decision, every relationship.
We operate as a small, focused team, with real depth in Laravel and Flutter and the comfort to take on projects in any other platform when it makes sense. We would rather say "no" to the wrong scope than "yes" to anything.
Most of what we deliver is built on Laravel (back-end and APIs) and Flutter (cross-platform mobile). It is where we have the most depth, the most internal libraries, the most scars — and therefore where we deliver faster, with less risk.
When the project calls for it, we also work with Vue, React, Node.js, Python (FastAPI), Kubernetes, server infrastructure, third-party API integration, and distributed architectures. We do not pick stacks by trend. We pick by what is right for the problem.
Platform for detecting and correlating mobile device presence patterns in intelligence and public security contexts. Distributed architecture on Kubernetes, two production clusters in isolated environments, real-time ingestion and analysis of large data volumes, machine learning pipeline. The studio's most technically complex work to date. Client under NDA.
Continuous full-stack development for a credit-market fintech, focused on the consultation, negotiation, and registration of receivables — direct integration with registrars and with CIP (Brazilian interbank clearinghouse). A technical layer that demands strict security and regulatory compliance. Laravel back-end, Vue front-end, Flutter mobile app.
Maintenance, evolution, and migration of an ERP system serving Brazilian retail chains with active production clients. Legacy version (CodeIgniter 3) running in continuous production, alongside development of the new version (Laravel 12 + Vue 3). Includes auxiliary services: multi-session WhatsApp bridge, printing agent, and multi-client iFood proxy.
Custom operational management system for an auto service chain in southern Brazil. Laravel + Vue back-end, Flutter mobile app, integrations with workshop flow, service order control, and AI-assisted diagnostics.
Institutional website and social media integration system for a residential painting company based in Santa Monica, California. Bridge between Pinterest, YouTube, and Substack, automating content publishing and synchronization. Delivered, currently on standby awaiting the next phase.
Middleware and operations panel development for a consultancy specialized in digital marketing. Dedicated server infrastructure, third-party system and e-commerce integration.
Institutional website development for a hotel in a tourist region of southern Brazil. Small in scope, same standard of care in the details.
We start with a conversation to understand the scope, timeline, and technical context. If it makes sense for both sides, we move to a proposal. If it does not — either for the structure of your project or for our capacity at the moment — we say so openly.
Yes. We have delivered projects for clients in other countries, in English. We operate from Brazil, with Brazilian working hours and billing, but communication and documentation can be in English.
Projects with poorly defined scope where the client is unwilling to invest time defining it, projects with tight deadlines that compromise technical quality, and projects where the required technology is outside our real depth — in which case we recommend better partners.
