I am a veteran software architect, enginevolunteerer and game developer who began his career in 1998 with a vast skillset of of technologies across the stack in the spaces of online multiplayer gaming, social networking, video streaming/sharing, peer-to-peer technologies, Developer SDKs, scientific research, artificial intelligence, data mining/analysis and virtual reality systems. Besides engineering, I have experience in project management, internet marketing , software/game design, UI/UX development and graphic design. My strengths include being a quick study, which has provided me a lot of broad knowledge of different technologies over the years, my creativity and passion for invention which has allowed me to find better solutions to given systems and pioneer new software solutions to increase functionality and profitability. I work best in startup environments allowing me to wear many hats and invest myself in the success of the business. I have a business mind and entrepreneurial passion, constantly developing business plans and prototyping new app inventions as well as reading up on new technologies to know as much as I can about my field.
Leveraging in-depth of software and web technologies from legacy to cutting-edge, coupled with expertise in engineering and scaling software stacks for millions of users, I help businesses to develop robust applications for their customers that outshine competition, maximize their profit margin by introducing new technology and inventing software to replace more expensive and less robust legacy systems, while also adding new features and functionality to increase functionality, usability and ultimately users/traffic that will be maintained through consideration of emerging technologies. My expertise extends to also helping clients with marketing solutions to generate sales leads, grow web traffic and mobile app usage.
My services also include helping new ventures get from idea to MVP and onward. My experience can help to develop a tech stack for web and mobile apps that considers technology changes, competition, consumer psychology, cost, scaling and profitability. My talent is to be able to take any idea and make it into a software reality. I have had experience developing solutions to complex business challenges as well as replace current designs with better ones. Finally, I help entrepreneurs to launch successful businesses by inventing and designing original technology that targets untapped niches in the technology market.

“ I had the pleasure of hiring Lehel in 1999 at First Consulting Group. Lehel had a very positive can-do attitude as well as being a very quick learner. Although he was only with us for a little over a year, he became an integral part of the team. ”
“ I have known Lehel for about 5 years now. First as an undergraduate student in my UCLA Psychology course on Learning. Lehel did very well there and approached me after the course was over about working on a modeling project. About 2-3 years ago, I approached Lehel about joining a company I was founding called Pigeon-Systems, Inc. He joined as one of three founders, and is currently CTA of Pigeon Systems, Inc. Lehel has a very strong background in computer science, with particular strengths in machine learning and AI. He is forward thinking and creative, and his completed work has always been of the highest caliber. He works well on his own, but also contributes to group projects. I really value his technical skills, creativity, and open mindedness, as well as his willingness to get his hands dirty in all aspects of our budding startup, not just the technical side. Lehel is not just a technical "yes man" but challenges me and the other founder with critical questions and analysis. This is an asset for sure! ”
“ Lehel is a super expert in software development. His work is highly commendable. ”
“ Besides the above 3 top attributes --- Lehel is personable, does excellent work, produces good value, is punctual and is trustworthy. A good man indeed! ”
“ Lehel and I worked at BH development on an online poker gaming system. The system was relatively complex with lots of traffic in a 24/7/365 type operation. The work environment was very fast-paced with zero room for errors. Lehel learned the system quickly and was productive in no time, contributing to the development of the gaming system and related database work. ”
