Nicolas I.

Senior Developer

A developer, with extensive system administration and leadership experience, I build, analyse, and improve systems and have managed several diverse teams. I am able to work efficiently within teams, or as a team leader. Most of my experience has been on leading teams in smaller enterprises with high pressure on reducing operational costs. I have a keen spirit, am curious and have a massive thirst for knowledge. I am active in many aspects of my employer’s business, and not afraid to make constructive suggestions. I am able to learn and adapt to new technologies quickly. I love problem solving, and am able to invent, select and implement the best solutions, within the necessary criteria. Every decision I make has the business’ and customer’s needs in mind. I lead from the front, but support from the rear. Security and cost are ever present requirements in the systems I build and design. Career highlights: * Lead a project to reduce new customer onboarding cost by a third.. * Designed and built a scalable, highly available microservices-based backend. * Assembled a team of world-class engineers, developers and researchers. * Implemented software development methodologies and development best practices many times. * Created an environment of productivity and efficiency to migrate from a cowboy culture. * Built tools for and imparted knowledge to Operations to allow them to discover and resolve issues themselves. Built tools for non-technical administration. * Launched products to industry, involving customers in all aspects of the development process. * Built a CI/CD pipeline for mobile and backend development, to alleviate load and some responsibility on developers, and improve their productivity. * Built an API and associated web-based console for self-service usage.
