Led a team of 8 developers in migrating legacy authentication systems to a modern microservices architecture using Go and React. Implemented biometric authentication features supporting facial recognition and fingerprint scanning while ensuring compliance with PDPA regulations. Developed secure APIs enabling seamless integration with over 700 government services and 3,000 private sector applications. Key achievements included reducing authentication time from 45 seconds to under 3 seconds, implementing zero-downtime deployment strategies, and achieving 99.99% uptime for critical government services. Collaborated closely with cybersecurity teams to implement advanced threat detection systems protecting against sophisticated attack vectors. The enhanced platform now processes over 20 million authentication requests daily and has become the cornerstone of Singapore's Smart Nation initiative. Received the Public Service Excellence Award for technical innovation and was invited to present the architecture at STACK Developer Conference 2024. This project required deep expertise in distributed systems, security protocols, and the ability to work within strict government compliance frameworks while delivering citizen-centric solutions at nation-scale.","rating":5,"ranking":16,"position":{"position":"hero","next":null,"name":"Hero","description":"Hero es el máximo nivel de los freelancers de Workana.

Meu objetivo é sempre criar designs que sejam esteticamente agradáveis e funcionem bem tanto no desktop quanto no mobile. Trabalho com uma variedade de tecnologias, incluindo HTML, CSS, Photoshop, Illustrator, core e outros. Tenho muito orgulho do meu trabalho e gosto de me manter atualizado com as últimas tendências. Espero ter a oportunidade de trabalhar com você em seu próximo projeto.","logos":{"normal":{"url":"https://workana.s3.amazonaws.com/logos/02e25863533f2094980264841e760ce8/hy/WhatsAppImage20231221at214758_160_160.jpeg","width":160,"height":160},"thumb":{"url":"https://workana.s3.amazonaws.com/logos/02e25863533f2094980264841e760ce8/yq/WhatsAppImage20231221at214758_30_30.jpeg","width":30,"height":30},"profile":{"url":"https://workana.s3.amazonaws.com/logos/02e25863533f2094980264841e760ce8/ii/WhatsAppImage20231221at214758_192_192.jpeg","width":192,"height":192},"large":{"url":"https://workana.s3.amazonaws.com/logos/02e25863533f2094980264841e760ce8/sw/WhatsAppImage20231221at214758_300_300.jpeg","width":300,"height":300},":original":{"url":"https://workana.s3.amazonaws.com/logos/55277f41a550db8a3848550985b4809c/bb/WhatsAppImage20231221at214758.jpeg","width":1440,"height":2560}},"country":"BR","lastActive":"2025-12-21 11:11:54","created":"2021-07-26 08:33:19","open":4,"active":0,"completed":"7","rating":"5.00","paid":7,"verifiedPaymentMethod":true,"worker":{"id":3855513,"slug":"matheus-kempes","canInvite":false,"skills":{"467":{"id":467},"469":{"id":469},"485":{"id":485},"452":{"id":452},"379":{"id":379},"509":{"id":509},"954":{"id":954},"894":{"id":894},"905":{"id":905},"362":{"id":362},"67":{"id":67},"437":{"id":437},"499":{"id":499},"525":{"id":525}},"history":"Comecei a trabalhar como freelancer com 19 anos, e desde então desenvolvi um grande portfólio de trabalhos para diversos clientes.
