With 14 years of experience in software engineering, I have honed my expertise in developing robust, scalable applications, initially focusing on Java, and more recently embracing Go as my primary programming language. I also have significant experience with C and NodeJS, allowing me to tackle complex backend challenges with ease. My passion for Go stems from its simplicity, efficiency, and the delightful developer experience it offers. Throughout my career, I have worked with a diverse range of technologies, which has allowed me to adapt to various project requirements seamlessly. I am particularly proficient in using Postgres, but I am also experienced with a wide array of relational and NoSQL databases. I have had the privilege of contributing to both large corporations and innovative startups, where I've often written the very first line of code, transforming visionary ideas into functional software solutions. My extensive background in both structured environments and fast-paced startups equips me to handle projects of any scale with agility and precision. Whether you need a seasoned developer to build from scratch or to enhance existing systems, I am committed to delivering high-quality, efficient solutions that align with your goals. Thank you for considering my profile. I look forward to the opportunity to collaborate and bring your ideas to life.
