Expert C#/.NET Developer Newly Returned To Upwork. First Hire Discount

United States - Tests: 21 - Portfolio: 8

If you don't have IT or software project experience, please don't contact me (unless you're a trusting adventure-seeker :) Bring Your Own Designer! IT Industry Knowledge Includes: - Best-practice Design & Implementation - B2B & B2C e-commerce - Systems Automation - BPR/Workflows- SaaS/Web 2.0 - Cobranding Vertical Industry Knowledge Includes: - Real Estate, Construction and Manufacturing management systems - Insurance (workflow) - Digital Media (distribution and conversion automation) - Healthcare (data collection & management) Some Background Information: - I have designed, implemented, and administered a wide variety of m$ft infrastructures, operating systems, servers, and applications for over 10 years. - I manage Apache, NFS, Samba, Asterisk, Bind, and other services on Red Hat-esque (CentOS, Fedora) servers. - I have been working with .Net since it was in beta. Before getting into C#, I used VB.Net for several years. - I've been writing enterprise-scale business and data layer code for over 4 years. - I've been managing and programming Microsoft SQL Server since version 6.5 (and am up to date on 200X), and Microsoft Access for many years. - I've worked with MySQL/SQLite and PHP (4+) as a hobbyist for several years. I can perform most any task required to update an existing site, but am probably not suited for a new development project in PHP.- Prior to .Net I programmed in traditional asp using VB Script, COM & DTC. - I manage my own dedicated windows 2k3/8 servers with multiple running applications and servers. - I have experience with a wide variety of third-party components and controls., and can assist in integration, middleware, queuing services, etc. - I'm not a graphic designer, and prefer to leave site layouts and graphics to someone more suited to that type of work. I am ok with creating basic layouts (and working within the popular graphics editing programs), but for a polished look, I'll either work with your designer or contract to another party on your behalf to acheive the look that you're after. Getting What You Pay For: Sure, you can find loads of developers here and on other similar service sites at a fraction of my rates. Why would you pay me? - I will stand behind my work. If you're unhappy, we'll fix it. - I will not charge for time spent figuring out how to solve general technical problems. If I don't already know how to implement a relevant solution, I will spend MY time researching and figuring it out. We're supposed to be professionals, and if we don't understand what the problem is, we shouldn't be charging you. Besides: each time I solve a unique problem, it makes me more effective; for you, me, and my next happy client! NOTE: Most of my work is done for companies' internal intranet, operations and LOB applications. I've added a few items to the portfolio, but please ask me about the other work which I can't showcase. While I'm often bound by NDA/Confidentiality agreements, I can explain more about my background in a general way than is illustrated publicly.

Nebojsha Matic

AWESOME Web project manager and data analyst

Serbia - Tests: 2 - Portfolio: 1

Experienced IT manager (over 6 years on different management positions). Career I'm pursuing would include: - UML methodologies for planning both front-end and back-end development. UML standards in gathering requirements and interviewing the users. (even though recommended for app development makes miracles in web dev as well. Makes your job much coherent and with no additional project changes). - Charting software (gliffy, Enterprise architect, LucidCharts) - Agile methodology (Scrum and Kanban, even made my own adaptations on few of my last jobs. I guess this beats "by the book" approach) - Task management software (JIRA, Basecamp, Asana, Trello....practically I've tested troughly or used most of ones that exist on the market). - I understand version control software (GIT) and DEV-TEST-PRODUCTIVE set up. (I dont do the code and couldn't set stuff up, but I can point developers in right direction) - I have worked on QA of many sites - I have run the daily stand up meetings and tracked lot of projects already, so I'll be able to fulfill all the tasks you had listed with great efficiency and bring value in $$'s to your company. - I have experience with Google Analytics, Crazzy Egg ( heatmapping software), conversion driven design and sales copies (I don't write them, but I'll be able to recognize good content and to give proper suggestions). All this give me the power to manage building of SUCCESSFUL sites and apps. All those allow me to overview the cash flow on projects, manage them with respect to the budget of the project, and work with You closely on general strategies. I've hired a lot of developers,designers, content writers.... via oDesk or other online service. I can handle tasks that require me to learn new things fast and provide solutions. I'm also the one to get help via regular chat and phone support. I've worked for a bit longer then a year as a call center representative. This gives me ability to handle support stuff and get the solutions. For 5-10 smaller projects it would probably take 10-15hours a week of my work to get everything running smoothly. Your support of my suggestions is required. I'm able to edit WP themes and do smaller adjustments myself. (I realized that lot of tasks in WP are faster to solve then to assign to a developer)
