Alberto – JavaScript, React, Typescript

Industrial and power plant application

Led the frontend development of a mission-critical Image Analytics platform's web application, serving 10,000+ power plant personnel across Mexico and Germany facilities. Implemented responsive and intuitive user interfaces that streamlined visual data processing workflows.

Engineered high-performance React components and state management solutions handling 100,000+ daily image analyses, ensuring smooth rendering and optimal user experience even with large datasets.

Spearheaded the development and deployment of major frontend features through an agile methodology, including real-time image processing previews, advanced filtering systems, and interactive dashboards. Consistently delivered ahead of schedule while maintaining zero critical bugs in production.

Architected robust frontend integration solutions to connect with core backend services and multiple Siemens Energy third-party platforms through RESTful APIs. Implemented comprehensive error handling, loading states, and data caching strategies. Successfully collaborated with 3 international teams to ensure seamless user experience during system integration.

Application for tenants and application for real-estate purchases

Led the end-to-end development of two applications while mentoring a team of 5 junior developers, fostering their growth in React, Node.js, and cloud technologies.

Architected and deployed a comprehensive Tenant Issue Management System handling 1,000+ monthly maintenance requests across multiple properties. Implemented real- time status tracking, automated notification system, and a mobile-responsive interface, reducing response time to tenant issues by a large margin and improving customer satisfaction.

Designed and launched an internal Enterprise Resource Management solution streamlining procurement processes for 100+ employees. The system centralized purchasing data, automated approval workflows, and generated real-time financial reports, reducing processing time and cost savings through better spend visibility.

House configuration application

Built a complete application that allowed our users to configure the structure of their houses. Leveraged strong communication skills to facilitate cross-team collaboration, resulting in on-time project delivery. The CEO told me at the end of the contract that the presentation to stakeholders was a success and everyone was super happy with the application.

Chat application

Led the development of a sophisticated customer support chat application that streamlined communication between users and support agents for enterprise-level products. Implemented real-time messaging capabilities and intuitive user interfaces that significantly improved the support experience. The solution was successfully deployed for Telekom, a major telecommunications provider, demonstrating its scalability and reliability at enterprise scale. Key achievements:

• Architected and built a responsive single-page application using React and TypeScript, ensuring type safety and code maintainability
• Implemented efficient data fetching and state management using React Query, optimizing application performance and reducing server load
• Designed reusable component libraries that accelerated development cycles and maintained consistent UI/UX across the platform
• Integrated real-time messaging features while ensuring optimal performance and reliability for high-volume customer interactions
• Later, once the team and product requirements grew, I was tasked to transition the app to a micro-frontends architecture.

Power Plant software

As the Founding Engineer, led the technical vision and architecture of an early-stage startup project, demonstrating both leadership and hands-on development expertise.

• Architected and implemented a scalable front-end infrastructure using React and TypeScript, establishing crucial foundations including state management patterns, component library architecture, and build optimization strategies
• Designed a comprehensive design system and component library that accelerated development velocity and ensured consistent user experience across the platform
• Engineered an extensible API architecture using Node.js, implementing RESTful endpoints with future scalability in mind while following industry best practices for security and performance
• Established development workflows and technical standards, including code review processes, testing protocols, and documentation requirements
• Created CI/CD pipelines to automate deployment processes and ensure code quality through automated testing
• Mentored and onboarded new team members while maintaining technical documentation to facilitate knowledge sharing
• Made key technical decisions regarding stack selection, third-party integrations, and infrastructure planning to support future growth

Financial advisor software

Worked on a fintech application for the number 1 financial advisor in Germany named DVAG. I owned the development of multiple heavily used micro-frontends and high traffic TypeScript microservices. I participated in multiple infrastructure changes:

• Removed GraphQL server and replaced it with REST
• Transitioned all our React codebase from JavaScript to TypeScript
• Decoupled the monolith frontend into micro-frontends
• Replaced our Kotlin(Spring Boot) backend to TypeScript, Node, and Express. And moved to a microservices architecture.
• Increased application performance by 30% by optimizing React components All these changes improved the speed of development greatly because the entire codebase was in Typescript, and it was easier for the company to hire TypeScript developers to work on both client and server. The onboarding was improved also.

Web application for Romanian farmers.

Collaborated within a cross-functional team to develop an agricultural monitoring platform serving Romanian farmers, enabling data-driven decision-making for crop management. *Implemented responsive React components for real-time visualization of sensor data, utilizing TypeScript for improved code reliability and maintainability *Architected efficient GraphQL queries and mutations to handle complex data relationships between soil metrics, weather conditions, and crop health indicators *Worked alongside backend developers to design and integrate RESTful APIs using .NET Core, ensuring seamless communication between IoT sensors and the web application *Participated in implementing automated testing strategies, achieving 85% code coverage for critical monitoring features *Contributed to the development of an offline-first architecture, allowing farmers to access vital crop data even in areas with limited connectivity *Optimized application performance through code splitting and optimistic updates, reducing initial load time by 40%

Software integration with Coca-Cola fridges with products recognition and classification

Developed software applications for local companies during college utilizing JavaScript, jQuery, Node, and React. Implemented innovative solutions to meet clients' specific needs and requirements. Collaborated with team members to ensure successful completion of projects on time and within budget. Demonstrated strong problem-solving skills and attention to detail in coding and debugging processes.
