That is not actually a beam. Same as you would for a perpendicular joint. No brackets, just toe-nail it. The span is not nearly wide enough to worry about a bracket. One other thing. I cannot really tell, but I don't see concrete piers. Those stupid cap blocks will be moving vertically. They should never be used for footings. They make a decent boat anchor I have read. Maybe invest in a roll of string. I see the 2 by on the right hand side not parallel with the double side 2 by. The right angle at the top of the picture is not at 90 degrees according to my software. More of about 92 to 93 degrees.
