Description

Do you need to develop an application, create a web platform, or improve an existing digital product?

I am a Mobile and Full Stack Developer, specializing in converting ideas and business needs into functional, intuitive, and easy-to-maintain solutions. I can help you with developing a project from scratch, adding new features, resolving bugs, and supporting existing applications.

I primarily work with Kotlin for native Android application development, with ReactNative and Flutter for hybrid solutions, and with React, TypeScript, and Node.js for web solutions. I also have experience developing projects with Laravel, PHP, MySQL, and WordPress.

I have participated in projects for the health, education, marketing, e-commerce, and financial services sectors, developing solutions such as:

• Native Android applications

• Web platforms and systems

• Front-End dashboards and functionalities

• APIs and Back-End logic

• Medical consultation systems

• Quiz mobile applications

• Online stores and virtual catalogs

• Corporate websites

• Email templates for digital marketing

• Application maintenance, support, and improvement

I differentiate myself by my ability to work in mobile, Front-End, and Back-End environments, adapt to the needs of each project, and quickly learn new tools. I maintain clear communication during development and strive to deliver stable, organized solutions aligned with the client's objectives.

Tell me what you need to develop or improve, and we will review the best way to turn it into a digital solution.

Implementation of complete microservices architecture in AWS.
I implemented the complete architecture based on microservices deployed in AWS Lambda, orchestrated by API Gateway with a centralized authorizer for access control.
Additionally, I designed and integrated a queue service for asynchronous processing of system messages, documents, and files, optimizing the overall platform performance.
Each repository was configured with its own CI/CD pipeline in GitHub Actions, enabling continuous automatic deployment to AWS Lambda and real-time notifications to the team via Telegram.

• Implementation of the Complete Digital Signing and Blockchain Registration Flow.
Functional Experience:
I led the technical and cloud implementation of the complete digital document signing flow, managed through microservices covering the entire process: authentication, document creation, signature reception, status updates, and version control.
As part of the system's technological evolution, I directed the design and integration of document and signature registration using blockchain technology, ensuring the traceability, immutability, and legal backing of each operation. This change was executed under my technical and strategic leadership, in collaboration with a blockchain expert, ensuring a secure, auditable, and scalable cloud implementation.
Furthermore, I designed and integrated a secure service for external signers without an account on the platform, accessible via an authorized and validated link, complying with internal regulations and digital security policies, leading technical decisions, code reviews, and architecture definition to ensure system quality, continuity, and reliability.
