I am a Structural Engineer with 10 years of experience in Designing and Drawings of steel, wood/timber and concrete buildings. I worked on projects of civil, industrial and commercial buildings and structures. For example Commercial: shops, stairs, facade cladding; Industrial: equipment frames, conveyor galleries, industrial ventilation system; Civil: cottages, roofs, stairs for private houses. I also developed standard solutions for warehouses, based on light gauge steel frames and created standard tables for purlin systems based on Z sections.
