A lo largo de mi carrera, me he especializado en crear soluciones tecnológicas innovadoras que abordan desafíos complejos, generando valor tangible y optimizando la experiencia del usuario.
Ciencia de Datos
Como científico de datos, he trabajado en la extracción y análisis de grandes volúmenes de datos, aplicando técnicas avanzadas de machine learning y análisis estadístico. Utilizo Python junto con bases de datos como MySQL para desarrollar modelos predictivos y sistemas de recomendación que optimizan procesos y mejoran la toma de decisiones. Mi enfoque está en crear soluciones personalizadas, con modelos diseñados desde cero para garantizar precisión y adaptabilidad.
Desarrollo de Aplicaciones Móviles
En el ámbito del desarrollo de aplicaciones móviles, he trabajado con Flutter y React Native, lo que me ha permitido crear aplicaciones nativas y multiplataforma. Estas aplicaciones no solo ofrecen interfaces intuitivas, sino que también integran inteligencia artificial para ofrecer experiencias personalizadas, como análisis de comportamiento, recomendaciones contextuales y optimización del rendimiento.
Desarrollo de Aplicaciones Web y de Escritorio
En desarrollo web y de escritorio, tengo experiencia en la creación de sistemas de gestión robustos y plataformas interactivas utilizando tecnologías como JavaScript, PHP, [Node.js](http://Node.js) y Electron. He desarrollado soluciones escalables y seguras que garantizan un rendimiento óptimo y una excelente experiencia de usuario. Me enfoco en la arquitectura modular, lo que permite la integración fluida de nuevas funcionalidades y la expansión sin fricciones.
Modelos de Inteligencia Artificial
Mi sólida experiencia en inteligencia artificial incluye el desarrollo de modelos para tareas como procesamiento de lenguaje natural (NLP), análisis de sentimientos, y automatización de procesos. Utilizo frameworks como TensorFlow y Keras para entrenar modelos optimizados que se ajustan a las necesidades específicas del proyecto, garantizando alta eficiencia y precisión. Estos modelos se integran a soluciones reales, optimizando procesos empresariales o mejorando la interacción con usuarios finales.","canInvite":false,"shouldShowHireMeDialog":false,"sameAsLoggedInCompany":false,"position":"iron","hourlyRate":"CO$ 25,000.00","hourlyWorkedProjects":0,"lastActiveLoginRelativeToUser":"December 26, 2024 10:39","lastActiveLoginRelative":"3 hours ago","registeredSinceRelativeToUser":"September 24, 2024 17:25","registeredSinceRelative":"3 months ago","recentBreaches":{"value":0,"label":"0 recent violations"},"workerSkills":[{"anchorText":"Data Engineer (Python) (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/data-engineer-python","isCertified":false,"title":"Data Engineer (Python) - Freelancers"},{"anchorText":"Data Science (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/data-science","isCertified":false,"title":"Data Science - Freelancers"},{"anchorText":"JavaScript (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/javascript","isCertified":false,"title":"JavaScript - Freelancers"},{"anchorText":"Arduino (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/arduino","isCertified":false,"title":"Arduino - Freelancers"},{"anchorText":"PHP (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/php","isCertified":false,"title":"PHP - Freelancers"},{"anchorText":"C# (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/c-1","isCertified":false,"title":"C# - Freelancers"},{"anchorText":"MySQL (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/mysql","isCertified":false,"title":"MySQL - Freelancers"},{"anchorText":"Python (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/python","isCertified":false,"title":"Python - Freelancers"},{"anchorText":"Flutter (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/flutter","isCertified":false,"title":"Flutter - Freelancers"},{"anchorText":"HTML (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/html","isCertified":false,"title":"HTML - Freelancers"},{"anchorText":"WordPress (5 to 10 years)","anchorLink":"https://www.workana.com/en/hire/wordpress","isCertified":false,"title":"WordPress - Freelancers"},{"anchorText":"Docker (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/docker","isCertified":false,"title":"Docker - Freelancers"},{"anchorText":"Android (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/android","isCertified":false,"title":"Android - Freelancers"},{"anchorText":"iOS (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/ios","isCertified":false,"title":"iOS - Freelancers"},{"anchorText":"Artificial intelligence (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/artificial-intelligence","isCertified":false,"title":"Artificial intelligence - Freelancers"},{"anchorText":"Machine Learning (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/machine-learning","isCertified":false,"title":"Machine Learning - Freelancers"},{"anchorText":"Chatbot (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/chatbot","isCertified":false,"title":"Chatbot - Freelancers"},{"anchorText":"React Native (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/react-native","isCertified":false,"title":"React Native - Freelancers"},{"anchorText":"React.js (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/react-js","isCertified":false,"title":"React.js - Freelancers"},{"anchorText":"SQL Server (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/sql-server","isCertified":false,"title":"SQL Server - Freelancers"},{"anchorText":"Firebase (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/firebase","isCertified":false,"title":"Firebase - Freelancers"},{"anchorText":"Internet Security (3 to 5 years)","anchorLink":"https://www.workana.com/en/hire/internet-security","isCertified":false,"title":"Internet Security - Freelancers"}]},{"isHero":false,"profileUrl":"https://www.workana.com/freelancer/4ab7aba6c66daff73b4d9cd108c24321","profileLogoUrl":"https://cf.workana.com/logos/a59ed6451eebe3aaf9c1d0ded41f0212/dk/IMG_3612_160_160.jpeg","profileName":"Johan S.","hash":"4ab7aba6c66daff73b4d9cd108c24321","roleName":"Data Scientist","tagline":null,"isVerifiedAgency":false,"rating":5,"ratingLabel":"5 of 5.00","completedProjects":5,"badges":[{"title":"Explorer Membership","size":"small","position":"","profile":"worker","type":"membership_premium"},{"title":"Completed courses: Expert Freelancer","size":"small","position":"","profile":"worker","type":"course_completed"},{"title":"Freelancer gold","size":"small","position":"gold","profile":"","type":"gold"}],"country":{"name":"Colombia","img":"
