We specialize in projects where multiple technologies must work together seamlessly — software with hardware, cloud with automation, and logic with real-world operational constraints. Our work is driven by solid architecture, clean implementation, and solutions designed for long-term use, stability, and growth. 🔧 Core Capabilities Systems & Full-Stack Development End-to-end design and development of web platforms, backend services, APIs, dashboards, and mobile applications, built for scalability, security, and maintainability. Cloud, DevOps & Infrastructure Architecture and operations across AWS, Azure, and Google Cloud, including CI/CD pipelines, deployments, monitoring, performance optimization, and production hardening. Automation & Integrations Custom automation, workflow optimization, system integrations, bots, and backend processes to reduce manual work and improve operational reliability. Embedded Systems & Industrial Automation Development and integration of embedded systems, IoT devices, electronics, PCBs, PLCs, SCADA, and hardware–software interfaces for industrial and automation use cases. AI & Data-Driven Features Practical AI and machine-learning integrations such as computer vision, OCR, analytics, and intelligent system enhancements — applied where they deliver real, measurable value. Specialized & Custom Solutions Blockchain systems, trading tools, telephony platforms, and other domain-specific solutions when projects require deeper technical customization. 👥 Team & Delivery Model For larger or time-critical projects, I work with a small, trusted technical team, while personally managing and reviewing all work. This ensures clear communication, consistent quality, and a single point of accountability for the client. 🤝 Post-Delivery Support Delivery does not end at handover. We provide clear documentation, support, fixes, and ongoing assistance when required, ensuring systems remain stable, understandable, and easy to maintain over time. Our approach is reflected in consistent positive feedback from previous clients, who value technical ownership, clear communication, and dependable delivery. If you’re looking for a technical partner who thinks long-term and takes responsibility beyond launch, Rashid Tech Solutions is ready to support your project. méně -
