You have a good build and I would say 10kdps is not too bad. I would advise doing a thorough search online and a good starting point is the DPS Leauge.
First thing I would do is perhaps get the correct duty officers - you need two/three that reduce cooldown time when using emergency power to weapons. If this is your main character and you really want to get the best DPS then poleron is not the best weapon of choice (neither are beams). Best DPS combos are with Cannons and Disruptors/AP/Phasers and for Romulans Plasma. Saying that I really prefer beam boats but I would consider better weapon type.
First thing that really will help unless you are going for a science build/attack you can get rid of exotic particles enhancements they really only boost science attacks (i think - I know its to do with science so I stay clear from it) I would also drop the improvements to projectiles as you currently do not have any slotted (that might change if you change weapon type - disruptors have some excellent torps)
Try to get more readiness on science and eng and really try and get Warp Core Potential. Improved Warp Core Potential. Warp Core Efficiency as they will help DPS. Also, I would drop the drain abilities as you BOffs are not using it and again it's a sci ability so you do not really need it.
I would look at Captain lvl Engineering traits particularly Auxiliary Subsystem Performance (if your aux runs low - more of an aux to bat problem) and Offensive Subsystem Tuning Weapon Subsystem Performance.
The weapons I can not advise in regards to Poleron - I usually go for disruptors.
I would advise reviewing your other ship gear for Elite Fleet Channeling Space Shields, Elite Fleet Protomatter Deflector Arrays, and then a rep Impulse Engine and warp core I advise Competitive Wargames rep - prevailing is very good.
There are a large number of consoles for DPS or even improved survivability that I suggest you do a thorough web search on or ask in-game channel that will help for science eng slots. Your tac slots are perfect
Then there are keybinds, correct star traits (best ones comes from some expensive ships), special duty officers, advanced flying and some ships all help your DPS.
I hope you find this useful and I know there is a lot here to look at and I am not saying your build is bad but if you want to get your DPS up then there is a lot of work to make that happen it will not happen overnight. start off with the easy less expensive stuff. Duty officers, traits then work on colony shields/deflector and rep warp/engine. Leave the weapons for now but it is something to consider along with consoles.
All the best
