About Me

My journey into development began as a teenager with a passion for customizing games, which led to managing platforms with 4,000+ concurrent users. This early experience taught me the critical importance of performance, scalability, and user experience.

Today, as Head of IT at a Large Telecommunications Company since 2017, I've built entire call center infrastructures from the ground up. My expertise spans from implementing PBX systems and automatic dialers to creating comprehensive CRMs that handle high concurrent requests and manipulate massive datasets.

I thrive on creating solutions that not only work but work securely and efficiently. Whether it's automating complex business processes, generating dynamic reports, or implementing robust security measures, I'm driven by delivering exceptional user experiences while maintaining the highest security standards.

My approach combines technical expertise with business understanding, having worked across telecommunications, BPO, commercial, and agricultural industries. I believe in building not just applications, but comprehensive solutions that grow with businesses.
