It is your responsibility to sweep your side of it. ★ You’re running a business, and if your mind is in 100 places at once, that’s fine – but if it means you aren’t paying bills on time then I will not chase you. It will just take longer to get your final work product, and you accept that. ★ Clear, direct, constructive feedback is the fastest route to an end result you love. ★ I strive to be kind, courteous and professional. Appropriate manners are required – rudeness is prohibited. ★ Don’t act like an amateur. ★ No lateness to meetings. ★ If you need something done faster, or a change in scope, let me know – before we get started. ★ I commit to honesty & directness. Our job is to improve, and it’s best done with hard truth from a second set of eyes. ★ If I can add value, I will speak up and give advice based on my experience & what I’ve seen that works well. ★ You’re always free to take my advice to heart, or ignore me completely. ★ My rates are neither the cheapest, nor the most expensive - but I ensure that the value my clients receive as a result of working with me, far exceeds what they have paid. ★ One cook in the kitchen please: Your team’s comments must pass through a single point of contact on your side. ★ Perfection takes time. Please be patient. ★ If you don’t love your end result please let me know ASAP. I will deliver one that you do. ★ I am in the business of exceeding your expectations. If I don’t, please call me out on it. ★ The client is always right except when they are wrong. ★ Relationships are important, and family time is sacred. Bear that in mind before sending late-night messages. 5-star developer who values communication. I can help bring your project to life with high-quality code, scalability, and organization.
