1.Nb5 immediately suggests itself- it is a double threat of Na7# and Nxd4:
1. Nb5! Bb5
There are no good moves, and no way to save the black queen without allowing mate. Probably best is to take the bishop at f4 with the queen, but that gives up massive material and still loses. Taking the knight is still going to be mate:
2. Bb7! Kb7 (Kd7 3.Qb5#) 3. Qb5 with 4.Qc6# unstoppable.
The position is ready for a direct attack on the black king: 1. Nb5! Bxb5 Of course not 1. ... Qxc4 2.Na7#. Other black first moves lose the queen, e.g. 1. ... Bc6 2.Nxd4 +- 2. Bxb7+! Kxb7 2. ... Kd7 3.Qxb5# 3. Qxb5+ Ka8/c8 4. Qc6#
I feel that black is in trouble after: 1. Nb5! Bxb5 (Qxc4? Nxa7#, else Nxd4, so taking on b5 could not be avoided) 2. Qxb5 Rd7 (Qxf4? Qxb7#, Qb4? Bxb7#, b6? Qa6#, Bc6? Bxc6 bxc6 Qb8#, rook move could not be avoided)
Those two dull looking moves seem enforced, and now it feels about time to speed up things here, finding a beautiful finish!
I try: 3. Bxb7 Kd8 (Rxb7 Qc6+ Kd8 Rd1 looked worse) 4. Qa5+ Ke8 5. Bc6 is at least well up with material. I'm not sure, may be here is something faster?

Nb5 having mate threat.
The white bishops are doing too well.
White can start with a queen sacrifice, which is actually a prelude to a neat sacrificial finish.
1. Nb5! Bxb5
2. Bxb7+! Kxb7
(2..... Kd7 3. Qxb5# )
3. Qxb5+ K--
4. Qc6#
1. Nb5! (threatening Nxa7# and NxQ) Bxb5 2. Bxb7+! KxB (only move) 3. QxB+ followed by 4. Qc6#
1. Nb5! (threatening Nxa7# and NxQ) Bxb5 2. Bxb7+! KxB (only move) 3. QxB+ followed by 4. Qc6#

1. Nb5! Bxb5 Of course not
1. ... Qxc4 2.Na7#.
Other black first moves lose the queen, e.g. 1. ... Bc6 2.Nxd4 +-
2. Bxb7+! Kxb7
2. ... Kd7 3.Qxb5#
3. Qxb5+ Ka8/c8
4. Qc6#
1. Nb5 threatening the queen.
If black takes the queen
1... Qc4, 2. Na7 is mate
if black takes the Knight then is mate with
1... Bb5, 2. Bb7 Kb7, 3. Qb5 Kc8, 4. Qc6 mate.
