Just do what the pros do; button mash.

Learn how to do Instant Running 2 - It's insanely good (mix it up with f,f+3 if they start sidestepping). Also learn his dash cancel (f+3, d/F~U). Use D+2 often. B+1+2 is a lot of positive frames on block and gives a free stomp (D+3+4) on hit. B+3 is a great 14 frame tracking move that wallsplats - it also has huge range, but it's high. D+1 is an underrated move. It's even on block so you can use 1,2,1 NCC bait and it gives free Stomp on hit. 1,2,1 is a fast (10f) Counter Hit Confirmable wallsplat/knockdown qcf+1 is a good long range safe whiff punish. 3,4 gives free stomp on hit. 3,1,2 above a floored opponent will track and interrupt if they try to wake-up kick between the hits.. D/B+3 to Crouch Cancel combo is amazing, but really punishable on block and it's a "seeable" low to any player worth their salt. His punishes are... 10f - 3,1 12f - 4,1 14f - B+3 15f - D/F+2 Dragunov is very, very strong at even an intermediate level.
