    Why we can talk business :- - I have worked for about 12 years in VAS companies developing their inhouse SMS & USSD systems. - I have designed, developed and done direct integrations to MNOs (mobile network providers) using SMPP, Parlay X and HTTP. - I have developed complex Bulk SMS portals to manage all aspects of a PRSP including clients management, phonebook(contacts), bulk scheduling MT, receiving messages MO (on demand services), SMS subscriptions (premium services), Delivery Reports configuration and routing, SMS reselling, automated balance topup especially using payment gateways and mobile money. - I have deployed Kannel to manage connectivity to SMSCs and subsequent routing and for smaller applications deploy multithreaded applications (Java) to handle the MT sending. (You can check the demo site at http://188.166.146.151/v3/web/ username:admin password:123456) Am committed to the projects I work on and need to see them through to completion. I understand that solving the user's problem is the end goal. I stay up to date with the latest trends and are excited to learn new languages, tools, and best practices. I thrive in teams and projects that span timezones and cultures. I hold a Bsc in Software engineering having attained a 2-1 thus am very conversant with the best software practices and standards from the complete Software Development Life Cycle to the final hand over to clients. I Have developed both back-end (extensive) and frontend systems using HTML, HTML5, JS, PhP (both procedural and OOP) ,Java and MVC frameworks (Yii, Yii2, CodeIgniter & Laravel) and database like Mysql, Sqlite, MSSQL, Redis running on servers like Apache for over 10 years. Have developed USSD , SMS (I have advanced knowledge in Kannel messaging gateway, SDP) and Payments systems (including but not limited to Paypal, Stripe, mobile money- MPESA, Mobile Money) just to mention a few. Am very conversant with developing APIs for Integrating with 3rd party applications. I have developed RESTFUL APIS using both JAVA and PhP. I have also developed/consumed protocols like XML-RPC, SOAP, HTTP and ISO. I have handled complex integrations with systems like T24 (banking) and ClearVision (shares trading). I embrace code versioning and collaboration tools and thus I have advanced experience in subversion (SVN) and GIT. In most of my projects, I use AGILE methodology where I engage my clients after every major module, walk with clients through the module, make the necessary adjustments then proceed to the next. I deploy monitoring systems once I develop a solution. To do this, I have prowess in Nagios monitoring system which I can easily configure to send SMS or Email notifications to alert configured users. I develop solutions that are secure by default. 2-Factor Authentication comes as a standard in all web based solutions. Client can either decide to use SMS, email or Authenticator apps (eg Google Authenticator) to receive auth tokens. I also make sure the system has descriptive audit trail to enable the system owner keep track of what is happening behind the scenes. I have developed systems both Windows and Linux platforms for several years and thus can administrate any system in those platforms. I develop solutions that have a futuristic approach with an aim in incorporating elements of Artificial Intelligence, Machine Learning and Data Analytic. When am not programming, I usually take out my violin and start making some music covers of popular songs though I have been a beginner for a while now. I also like jogging especially in the mornings and I have been beating my record (by a few seconds though) every new run. Am a fun person and usually excited from learning new technology every day.

    Several companies have trusted me to help them automate their data processing workflow, replacing outdated spreadsheet systems and building RESTful APIs. Hi, I'm Paul, a software engineer. When we are working together, we both want the same thing: fixing your code-related problems. Need a backend to handle the services you offer to your clients? I will code one for you with Django! Have a backend, but you are missing the frontend? I will build it for you using ReactJS and Material-UI! Already have your site developed but need to host it on a server? I will deploy it on a cloud-based provider like Google Cloud Platform (GCP) with Docker and Kubernetes! Struggling to make your project work? I will review it to make sure that you are using the right tool for the right task and get you up and running! WARNING!: If you are looking for someone that does cheap, run-of-the-mill work, I can't help you. I work with the kind of people who care about quality, since you know that getting a job well done will help YOU take more money home. If that sounds right up your alley, then I'm the one you are looking for. Here's what to do next: Send me a message telling me about your business and your project. If it seems like a good fit, I'll write you back and we'll take it from there.

In October of 2020, I founded Ari Integration. The company is rapidly becoming a premier Microsoft partner in the Southeast. I’ve never faced an IT challenge that I couldn’t overcome.
