About Me
Beyond the Code
Online I go by nickouv — I am Nick Kouvalias. Based in Sweden, planning to move back to Greece; eight years shipping telecom, WebRTC, marketplaces, and industrial vision systems.
> Senior full-stack engineer / DevOps with experience from Ericsson (cloud-native telco, Kubernetes, Kafka, security) and Onmo (low-latency WebRTC gaming and playable ads, hybrid AWS + on-prem, CI/CD from scratch).
> Today I freelance and build products: WorkSpo (Laravel + Flutter marketplace), Lifelike Agents (voice automation with LLMs and Twilio), and experiments in applied AI video tooling.
> Earlier I led engineering for Talos Robot Vision (welding seam tracking, C# / .NET, Azure, OpenCV, industrial robot integrations).
> I like small iterations, measurable outcomes, and production habits: observability, incident response, and reviews people can follow later. EU citizen; English and Greek fluent, Swedish comfortable.

Thoughts & Writings
Notes on shipping production systems: WebRTC, hybrid infra, Laravel/Flutter marketplaces, voice on real phone lines, and telco-sized habits that still fit in a small team.
Weekly releases across AWS and the rack
Shipping low-latency products when half the footprint is cloud and half is yours taught me that identical pipelines beat heroic SSH. Notes from Nomad, Terraform, and boring Fridays.
Laravel and Flutter: one product, two codebases
Contracting on a two-sided marketplace meant guarding API contracts, Stripe webhooks, and map UX across a Laravel core and Flutter apps. Practical seams I still reach for.
Voice agents on real phone lines: what breaks first
Twilio, speech-to-text, LLMs, and text-to-streaming audio sound magical in a slide deck. In production the pain is barge-in, latency, and failure speech. Notes from building voice automation.
