EMPLOYMENT HISTORY
REDLINE COMMUNICATIONS INC., Markham, Ontario 2001 - 2008
Senior Mechanical Design Engineer
➢ AN-50e/AN-30e and T-58: Backhaul broadband systems, consisting of sheet metal chassis’ and a die cast enclosure.
• Led the design from concept to production, including prototyping and testing.
• Completed all designs of wire/cable assemblies and custom antenna mounting brackets. Completed all hardware selection, drawings and all Bill of Materials. Testing consisted of vibration, temperature, shock, drop, environmental (thermal, humidity), salt spray, IP67, wind loading and sun loading. These tests were conducted at Redline and also third party sources.
➢ AN-80i: Backhaul broadband system, consisting of a die cast enclosure.
• Led the design from concept to production, including prototyping and testing.
