About Me

I'm a technology and security consultant who got fed up with an industry full of buzzword-slinging consultants and overpriced solutions that don't actually work. I've seen too many businesses get burned by 'experts' who talk a good game but can't deliver real results. That's why I focus on practical solutions and honest communication - no BS, no inflated promises, just solid technical work that solves actual problems.

Personality

I'm pretty direct - I'll tell you what's broken, what's not worth fixing, and what vendors are trying to sell you that you don't need. I genuinely enjoy solving technical problems and learning new things, though I get bored doing the same work for too long. I take the work seriously but try not to take myself too seriously.

Passions

I get genuinely excited about helping businesses use technology effectively without getting ripped off or overwhelmed by complexity. There's real satisfaction in cutting through the noise and implementing solutions that actually work for people's specific situations.

Interests

Outside of work, I'm into table tennis, chess, and ice skating during winter. I spend way too much time tinkering with home labs and running my own servers - the line between work and hobby gets pretty blurry when you actually enjoy the technology. I'm always working on some project or learning about new tools and systems.

Goals

Build a consultancy that does honest work at fair prices. I want to work with clients who value straight talk and practical solutions over flashy presentations. Ultimately, I want to have fun solving interesting problems while helping businesses avoid the typical IT consultant nightmare.

2024-Present

Byteron Inception

After taking a step back from the Security & Technology industries due to growing frustration, I embarked on a career break that allowed me to reevaluate my personal and professional goals.

One of the conclusions was the inception of Byteron.

I hope to help clients understand the impact of their technical decisions, and help move the bussiness forward in a way that is both secure and functional.

Why

After years in the technology and security industry, I got fed up with the snake oil solutions, vendor bias, and fake expertise everywhere. Too many consultants are more interested in selling whatever pays the highest commission than actually solving your problems. The industry is full of people giving advice about technology they've never actually implemented.

As an independent consultant, I can tell you what actually needs fixing without worrying about sales quotas, vendor relationships, or corporate politics. More importantly, I can actually build and deploy the solutions I recommend.

My goal is to be the technical expert you can actually trust, not just another salesman peddling the flavor of the month. I'm here to solve your technical problems from start to finish, not sell you someone else's product and disappear.

No Vendor Lock-in

I recommend what actually works for your situation, not what pays the highest commission or keeps vendor partnerships happy.

Complete Solutions

From strategy to implementation - I don't just hand you a report and walk away. I build what I recommend.

Broad Technical Expertise

One consultant who understands everything from infrastructure to security - no need to coordinate multiple specialists.

True Independence

No corporate politics, sales targets, or vendor relationships affecting my recommendations - just honest technical advice.
