I'm planning and developing iOS and macOS apps with Objective-C and Swift (VIPER, MVVM, Cocoa, Cocoa Touch, Core Data - of course, performance optimizations, low-level debugging).House Rules:* If I can't make it by a deadline, I tell you in advance, no exceptions(Even if my pet hamster got sick, etc.) (Though I've never missed a deadline in my professional life.)* I used to work with small and medium-sized teams, motivate, and educate people on a team if needed* You can expect honesty, punctuality, and fair play from me, but I require that, too(i.e., don't be a jerk, and I'm completely attentive and loyal to you and your project)* You're getting a bonus marketing analysis of your product, business, or idea. But only if you want to make more money and want to listen. It's up to you. With my 20+ years of direct marketing experience, I MUST assess your unique situation. It's in my DNA, so to speak.I have other skills that may be useful to you, but, frankly, I'm not that great in some of the following (but good enough and can learn fast):* Data Science and ML (NumPy, Pandas, SQL, Tensorflow and Keras, and obviously Python). I have a basic utilitarian understanding (i.e., I can wrangle data with Pandas, visualize it with Matplotlib and/or with Seaborn, get the data ready to train a NN, train it, see which algorithms are better for this particular task, and so on, and so forth. But I can't invent a new algorithm. I'm not a math-head.)* FreeBSD installation, tuning, and administration (I know how to get a system up and running, with all security in place, ready to accept requests)* Web programmings skills: Javascript / ECMAScript (Vanilla and React JSX), PHP (proper OOP or unmaintainable spaghetti if you insist), and basic Golang (small useful APIs and so on). And yes, I know how TCP/IP works, what OSI and TCP/IP network models are, and how they differ.* Speaking of PHP, I can fix any problem with Wordpress, Magento, Drupal, Joomla, and basically any similar products (The last 20 years or so, I was fixing various PHP projects from time to time. Sometimes it was my own urgent need. Sometimes my friends/colleagues were desperate, and I was saving their day.)
