Remote

Lead Software engineer at Hadron team building real time systems in Go and Linux. The product provides real time data to SSP partners meeting low latency and high throughput requirements such as response time <7ms and traffic more than 500K QPS in some data centres.

Edinburgh, Scotland, United Kingdom

Main responsibilities at Audigent are:- building and improving low-latency, high-throughput "real-time data systems" for Supply Side Providers in programmatic advertisement. Audigent's RTD system must respond within 7ms to the client. Busy data centres can reach up to 1.3M requests per second (Go HTTP server optimised for Linux and Ubuntu 22.04).- Designing and maintaining storage systems. Specifically, in-memory store (Go library), distributed key-value store (Redis and KeyDB), and cloud store (DBMS OLAP - ClickHouse) - Designing and maintaining observability and monitoring systems (Vector.dev, Prometheus, Grafana).- Developing and maintaining infrastructure code for the company's resources (using Terraform)- Developing and maintaining deployment scripts (using Ansible).- Leading a small team of 4 developers (fully remote with different timezones).

Falkirk, United Kingdom

Backend software developer, with experience in Go, PostgreSQL, Redis, Dgraph/Badger key value store, Docker, Git, gRPC, End to End tests, Unit tests. What I have accomplished:The past four years at Obashi, as a team have built two versions of the product purely in Go, using PostgresQL as the main database to store our data. The product was built as a RESTful API service using JSON.The authentication system was built internally, using Bearer Token authentication and JWT tokens. We used Docker to ship our product and the Docker Network to deploy the server , the postgres container and the UI container to a local network. Testing was a big factor of the development process, and mainly it was end to end tests with some unit tests for complex functions. Side projects during my time at Obashi was two micro-services using gRPC, one simple Authentication service and a mail service. The mail service was using a key value store of the email events, triggered by user actions, and go routines to send those emails to the user inboxes. For the authentication service we used Redis as a fast key value store for the jwt tokens.The last 6 months, Pavlos was contributing the front end of the product, which was entirely in Javascript and Vue.Js, delivering end to end (full stack) tickets.
