I developed and implemented custom audio systems for live events and broadcast productions, ensuring clarity, balance, and high-quality sound throughout each project. I worked extensively with professional-grade equipment from brands such as Yamaha, Allen & Heath, Shure, Sennheiser, QSC, Behringer etc. managing mixing consoles, wireless microphone systems, speaker arrays, and signal processors.

I led a team of assistant engineers and technicians, providing training and fostering a collaborative work environment. During pre-production, I participated in planning meetings to assess technical requirements and created detailed schedules for setup and rehearsals.

During live events, I operated audio systems in real time, monitoring levels and making on-the-fly adjustments using platforms like Dante, AVB, and SoundGrid. I quickly diagnosed and resolved technical issues, implementing contingency plans to avoid disruptions.

I collaborated closely with directors, producers, and performers to align audio with the creative vision of each production, ensuring seamless communication and execution. In post-production, I oversaw mixing and mastering using software such as Pro Tools, Logic Pro, and Ableton Live, delivering final audio assets that met industry standards and client expectations.nt fleet.

• Set up, maintained and operated audio recording equipment and performed troubleshooting and audio system breakdown for broadcasts.
• Prepared for recording sessions by selecting and setting up microphones.
• Maintained and repaired sound equipment.
• Customized live sound setups for corporate events, supporting clear communication and presentations.
• Led audio team in fast-paced environments, keeping projects on schedule and under budget.
• Solved complex audio issues during live events, ensuring uninterrupted performances.

I designed and implemented advanced audio systems for live events, corporate productions, and broadcast environments, ensuring exceptional sound clarity, dynamic range, and system reliability. I worked extensively with industry-leading brands, including:

• Mixing Consoles: Yamaha (CL5, QL series), Allen & Heath (SQ, dLive), Behringer (X32), Soundcraft (Vi series), Midas (M32)
• Microphones & Wireless Systems: Shure (SM58, ULX-D, Axient), Sennheiser (EW series, MKH), AKG, Rode, Audio-Technica
• Speakers & Amplification: QSC (K series, CXD), JBL (VRX, EON), L-Acoustics, Electro-Voice, Meyer Sound
• Signal Processing & Routing: Waves SoundGrid, Dante (Audinate), AVB, DBX, BSS, Radial Engineering
• Recording & Editing Software: Pro Tools, Logic Pro, Ableton Live, Cubase, Adobe Audition
• Control & Integration Systems: Crestron, Control4, Extron, Kramer, Blackmagic Design, AJA

I supervised and trained audio teams, coordinated with technical staff and vendors, and ensured all gear was properly maintained and optimized. I participated in pre-production planning, created detailed technical schematics, and led rehearsals to validate system performance.

During live events, I operated FOH and monitor mixes, adjusted EQ and dynamics in real time, and responded swiftly to any technical issues. I collaborated with directors, producers, and performers to align audio with the creative and logistical goals of each production.

In post-production, I handled multitrack mixing, mastering, and delivery of final audio assets, ensuring compliance with broadcast standards and platform-specific requirements.

I installed and configured smart automation systems for residential and industrial environments, specializing in high-fidelity (Hi-Fi) audio distribution and high-definition display integration. My responsibilities included structured cabling, system calibration, and seamless integration of AV components with control platforms (e.g., KNX, Crestron, Control4). I conducted site assessments, interpreted technical schematics, and ensured compliance with safety and performance standards. I also provided client training and post-installation support, optimizing system functionality and user experience.

I produced and edited audiovisual content tailored for social media platforms, including promotional videos, branded storytelling, and short-form visual pieces. I managed the full production cycle—from concept development and scripting to filming, post-production, and final delivery—ensuring alignment with brand identity and audience engagement goals. I operated professional cameras, lighting setups, and audio recording equipment, and used editing software such as Adobe Premiere Pro and After Effects to enhance visual impact. I collaborated closely with marketing teams to optimize content for formats like Instagram Reels, TikTok, YouTube, and Facebook, driving reach and interaction.

During my time working as an audio engineer at Emmplay, I was responsible for recording, editing, mixing, and mastering various music and audiovisual projects. I managed and operated the studio's technical equipment, ensuring each session ran smoothly and efficiently.

I worked directly with artists, producers, and clients, providing both technical and creative solutions to achieve the sound they were aiming for. I also oversaw the workflow in DAWs like Pro Tools and Logic Pro, using a variety of plugins and hardware to deliver professional results.

It was a highly rewarding experience where I not only strengthened my technical skills but also developed my ability to communicate and work effectively under pressure in a collaborative environment
