Cloud
My work has steadily specialised in web platforms on Microsoft Azure: scalable applications on App Service, serverless compute with Azure Functions, identity, security and DevOps around them. The certifications below map that ground.

About
Hello world! I'm Charalambos, a software developer with a heart for gaming. Every project is a chance to experiment, sharpen my skills and try what's new.
Games
In 2017 I co-founded Evistoria Games. Our first title, You Shall Not Break!, shipped on Steam in 2018, built in Unreal Engine 4. I also publish plugins for Unreal Engine and Unity so other developers ship faster.
Products
I build my own: , a SaaS engine and community platform for bowling, and , effortless photo sharing for events.
Writing
At thecodewrapper.com I write practical guides and tutorials drawn from real problems I've solved, also on Medium and dev.to.
BowlingOps is the engine. CyBowling is the experience.
The problem
Being part of the bowling community, I saw how much of the sport still ran on spreadsheets, manual scorekeeping and fragmented communication. I started building tools for single problems: leagues, tournaments, players, teams, rankings, results. They turned out to be pieces of the same system.
BowlingOps, the engine
A SaaS platform providing the operational infrastructure behind a bowling organisation: tournament management, league scheduling, players and teams, rankings, statistics, administration, communications and live scoring. It is built to be reused by clubs, associations and centres, with organisations, workspaces, permissions, reusable competition engines, automated workflows and a data model designed around the sport.
CyBowling, the experience
The public community platform built entirely on BowlingOps. Players discover tournaments, follow live standings, see their history, manage teams and build a public profile; organisations run competitions and keep members connected.
Why
To apply what I do professionally (cloud architecture, SaaS design, automation, APIs, real-time systems) to a sport I care about. A league shouldn't need a spreadsheet to know its standings. Every tournament still exposes a new edge case, so the platform keeps growing from real use: not just software for bowling, but infrastructure for a bowling community.
Built in Cyprus, for the people who keep the sport moving.
Sharing event photos should be effortless, for everyone.
Collecting photos from guests usually means messy group chats, endless email threads and lost moments. What began as notebook sketches became a platform powered by Azure, Blazor and modern web technologies. Picfony now runs events of every size, from intimate weddings to busy community gatherings, giving hosts every memory and guests an easy way to contribute.
