[TCPQuest]

About Me

I am a specialist engineer currently working at the largest company in Latin America, with broad experience in complex international projects. i speak Spanish and English, with working knowledge of Portuguese, I thrive in multicultural environments.
 

Expertise

I specialize in Java development, particularly in building and maintaining private game servers for Lineage 2 (L2J) all versios c4, interlude, h5, classic and essence. My deep knowledge includes multithreading, TCP packet manipulation, and runtime modification of Java classes through reflection and reverse engineering.
 

Core Skills

• Debugging and fixing complex issues causing resource leaks (memory, CPU)

• Developing custom systems and AI for game servers

• Direct TCP packet manipulation for efficient network communication

• Reverse engineering and dynamic class modification for rapid adaptations

• Applying design patterns (Command, Strategy, State, Mediator) to create robust architectures

• Integrating with relational databases such as MySQL and MariaDB

• Git version control with GitFlow for organized development

• Profiling using Pyroscope and VisualVM

• Observability with Grafana, Datadog, and other monitoring tools

• Experienced with Linux, iOS, and Windows environments
   

Looking For

Passionate about gaming and development, I am opening opportunities for freelance projects. I offer flexible payment terms for clients with a strong reputation, aiming to build lasting professional relationships.

If you need an experienced engineer capable of solving complex problems efficiently, I’m ready to help your project succeed.

Outside of the game world, I have expertise in AWS services, distributed web systems, GoLang, C++, C, and frameworks like Angular, Vue, and React, but I’m definitely not a designer! xD

If you’re interested, send me a direct message explaining what you need or the problem you’re facing, and I’ll provide you with a quote.

Charging €10 and €20? That’s not freelancing, that’s begging with code.

AI is free to do the work today.

I'm just getting started and don't have a reputation yet. I already have a stable job and earn a good salary as a developer.
 

It may seem like a low price, but I did some market research before setting this rate, and considering I don’t yet have a name in the Lineage2 community, I believe it's a fair starting point.
 

If you think the price is too low, feel free to hire me for your projects — I’d be glad to work with you.

He doesn’t even have a server. He’s just shitposting to farm points, pretending to be smart with his garbage memes. Total clown.

 

Good luck on your new beginning. I hope everything goes smoothly for you.

Anytime, I just appreciate your presentation. On the other hand, I have no respect for people who judge or disrespect others without the slightest clue.
