Golang Developers in Colombia

I'm an experienced Golang engineer, have built services around message driven architecures with various storage solutions, and also have built security services for end-to-end communication between microservices, along with other technologies (e.g. gRPC, Docker, distroless images, Linux, scripting with bash/Python, Terraform, AWS).

I'm Antonio Donis, a Senior Go Developer and Junior DevOps Engineer with a Systems Engineering degree from Universidad Pontificia Bolivariana. I've developed complex solutions such as the OpenVPN DCO driver interface and facilitated seamless communication through a pure Go API. With proficiency in both English and Spanish, I'm also ranked in the Top 1000 in HackTheBox worldwide, reflecting my strong problem-solving skills. My diverse expertise and competitive spirit continue to drive my impact in the tech industry.

I am a Golang developer with a focus on microservices with technologies such as gRPC, GraphQL, also REST API design, PostgreSQL, MongoDB, etc. I've developed several personal projects with Go, such as an indexer that takes information out of a large database file, processes the information, and sends it to ZincSearch to be indexed, finally to a Vue.js client, the user searches up a term, and the Zincsearch API gives back the fields that contain that term. Also, I have a cloud-native microservices eCommerce web application project, that is composed of 3 services, using gRPC and Protobufs for communication between services. This project is structured using hexagonal architecture, It uses Github actions to automate the creation of protobuf files. Includes observability with the following stack: Jaeger, Prometheus, Fluent Bit, Elasticsearch, Kibana.

I started my journey in the IT field in October 2019. Before that, I had studied the C++ language by myself. My first job at ISPRAS (Institute of System Programming Russian Academy of Science) was as a software engineer. (2 years) In ISPRAS Took part in projects Restoring debug information symbols of release builds using the disassembler and BCC algorithms, JVM optimization with LLVM. (C++, Java bitcode, LLVM, LLVM IR), Source generation for given language using grammar DFM. (Java, antlr4). And within these two years, I created my project Facebook scrapping daemons for statistics (python, neo4j, selenium). In 2021 I joined the new team of IntegralLabs. I am intense in blockchain technology. Now I’m managing a team for creating new-generation blockchain technology (C++, graphene, boost, cryptopp, openssl, fc). I have leadership and mentoring solid skills, also strong research skills. I have taught and onboarded new team members. I have huge experience creating (architecture and development) concurrent network programs like distributed systems. I know cryptographic algorithms and how they work. Now I’m using C++17 language. Frameworks and libs boost, graphene, fc, SSL, and custom-created APIs. After that, I joined the new team of Flow with the IntegralLabs team as Senior Software Engineer in crypto-oriented projects like crypto wallet creation. In spite of having four years of experience, I’ve worked hard on various projects, invested a lot of effort, and gained much more knowledge which let me handle new challenges.
