Tolga is a seasoned developer who built his own game —Remnants of Naezith— in three years. This game works on multiple platforms such as Nintendo Switch, macOS, Windows, Linux, and was published on Steam. This allowed Tolga to master C++ since the project was built without a game engine. His most vital skills currently lay in the C++ area, but he's pretty handy with SQL and Node.js, as well. All in all, Tolga is a code perfectionist who always ensures that he meets project deadlines.

Solo Game Developer

2014 - 2018
Remnants of Naezith
  • Solely developed, managed, and published the Remnants of Naezith game and its related websites. Coded the game with C++ and SFML only; sans a game engine.
  • Self-published the game, which has gained strong and overwhelmingly positive reviews (97%) and pushed to keep the game's quality at its highest without the need of a post-release big bug fix patch.
  • Implemented a level editor that allows players to make their custom levels. Made a custom level section to support levels made by the community with a rating system and leaderboards functionalities.
  • Made a React and Node.js site——that shows players, levels, leaderboards, and world records used and appreciated by the community. Built a Discord bot that syncs in-game ranks as Discord roles and reports world records to chat channels.
  • Coded the game to be cross-platform—supporting Windows, macOS, and Linux—, adding a wide range of controller support on all platforms in a way that all players can compete in the same leaderboards.
  • Optimized the game so that it ran smoothly at the highest graphics on a low-end laptop. Added a speedrun mode that lets players play the whole game without any UI interruption.
  • Developed a replay system that lets players watch the gameplay of all other players (any level) on the leaderboard and implemented highly detailed leaderboards and global rankings where players are constantly competing on.
  • Implemented a replay validator that constantly checks if all the top entries are perfectly recorded without any glitch or cheat. Coded an incredibly strong anti-cheating system that prevents any cheater from entering the leaderboards.
  • Managed a team of freelance artists, musicians, testers, and level designers. Collaborated closely with a ~300 player closed-beta community within a feedback loop of 3.5 years.
  • Maintained the development log and did the marketing of the game on Twitter, Reddit, and TIGSource forums. Presented the game in gaming conventions in Istanbul and Berlin and participated in many interviews.

Remnants of Naezith
Remnants of Naezith is a fast-paced precision platformer oriented around grappling hook mechanics.
Rush through levels and swing around obstacles, improve your skills to climb the leaderboards, or even create your own levels. The fun of swinging with grappling hooks and the amazing feel of acceleration makes a great combination during gameplay.
It was developed with C++ and SFML on the client-side and Express Node.js and MySQL on the server-side.

AtomicDEX Pro Desktop Wallet
AtomicDEX is a secure wallet and non-custodial decentralized exchange rolled into one application. It allows users to store coins and trade peer-to-peer with minimal fees without giving up control over their digital assets.
I made the front-end GUI with Qt/QML while my partner made the back-end API.

Antara Smart Chain Composer

A web application that lets anyone customize and deploy a smart chain in just minutes. Singlehandedly completed the entire web application using React for the front end and many techs, including Antara's, Node.js, MongoDB, and AWS for the back end.

Antara Gaming SDK
A kit which includes everything a game needs.
The main goal was to have a game engine that also had a blockchain database, for example, a leaderboard. I developed it with a partner. We used EnTT, SFML, Box2D, ImGui, Lua, and more. I made a 3D demo with 2D rendering.

Monstrous is a melee-combat-oriented action-adventure game featuring gothic horror characters entangled in fragile alliances and settling rivalries—all set within a free-roaming city amidst the industrial revolution.
The game uses C# and Unity.

An open-source ranking website for the Remnants of Naezith game that allows players to browse other players, world records, global rankings, levels, and leaderboards.
The game uses React and Node.js.
