With new experiences comes great responsibility

Hello Everyone,
I am an ordinary person with some highly looked after skills, not boasting about myself. But after coding in this IT industry for almost 5 years for the first time I am thinking:-
Is delivering the code my only responsibility or is there anything else I need to look into as well?

From last few month's I was highly involved in some entirely new domain which is financial, and when you play with the number you need to be highly focused, so unable to update my blog as well.

When I was working on the urgent deadlines and tight estimates and being from a healthy UI background like css3, html5, responsive design, knockout js, less etc. I was put on the SQL server and asp.net with grid views and some freaked out Telerik controls.
I know it's a learning for me and I can see why UX matters to every person in this entire world but not UI and you can write it on stamp paper.

User Experience, with logical and functionally correct code, is the need of the hour today.
All the needed information we can show in some excel but on the web you need a grid with all the functionality including global search and dynamic edit  batch edit.

And then you can have a co-worker who can become ill or who can have some urgent priority work which does not include your project. So it might be possible you are working on two-three projects together and handling everything together including two men's work. You can also have your personal problems as well it can be possible that your father, mother or even your girlfriend or wife may need you for help. Bogged down from everywhere, how will you handle all this with a manager shouting at you in front of 20 people.

So is delivering code is my only responsibility, being a developer what should I look into and how can I fix my overtime to regular office time and maintain my work-life balance.

Should I trust my manager or my company who is outsourcing me to Americans projects and giving me sleepless nights or should I look for better opportunity?

By the end of all the mishaps happened to me, I came to some conclusions as below in which makes me wonder and believe why management matters:

• Deal directly with end users, try to skip your manager, QA or BA
• Give daily or at least weekly updates
• If somebody is not working then tell it in a peaceful way without letting them know you are complaining to your reporting manager
• And one of the most important, do not touch the code without complete requirements and do not give estimates for development only, give estimates for the complete app development with testing in staging and QA environment
• For other colleagues code failure, and you are fixing it let everyone knows
• Be selfish, talk to everyone and keep a healthy rapport, especially with Business users, your managers will not say a word to you if your client is happy
• Divide the tasks initially
• Do testing, properly and ask everyone to do it
• If everyone is senior, do not get into ugly fights make peace and work, if it doesn't work out that way try to find out their mistakes and start assigning them task, try to be a boss
• Leadership quality is highly needed, you might need to control entire team as your team lead can be a jerk as well
• Work for yourself but also do not let deserving one let down

I hope my intentions are clear here.

Thanks
A frustrated developer
