The following developments were implemented for Accruent’s EMS software:Upgrading to the latest version of the .NET Framework.Migrating of calls to new API provider for IoT services.

I implemented bugs fixing and new requirements reported by the QA staff to the requests performed by the client to its e-commerce platforms (real estate and vehicles selling) both marketplace and seller centres. These solutions have integrations to third party platforms such as AWS and Vtex.

I implemented different components in T10 System, and developed Toll Collection Software for Highway Concessions. I optimized the Toll Collection Synchronization Module which allowed information (transactional and managerial) to be uniform in the Three-level Toll Operation (CCO- Operations Control Center, Station and Road). I developed the Unattended Payment Module that issues tickets and confirms payments at the Automated Payment Kiosks.I modified the Benefits Module (concession's toll-booth) that determines if a passing-through vehicle is entitled to discounts. I solved customer's dealings reported by the Technical Support Staff.

AutenTIC is a company that provides Digital Signing Services. I worked on the development of a platform intended to process the Scanner-Captured fingerprints. This platform consists of: Print-Capturing Desktop Component; a Backend Component, whose function is to mediate with the RNEC (Colombian National Registry of Civil Status) services -a government platform that performs the fingerprint matching-, and a front component; a web site that interacts with the previous mentioned components. The project was entirely developed with .NET technologies: WinForms, ASP .NET Core (WebApi, EF Core) and Databases SQLite and Oracle.

Development and testing of different components from a software implemented for an Information System Medical Test intended for drivers and security guards (When I left this project, it was under construction phase). I also participated in a project called Paynet, a solution designed for companies seeking to reduce process complexity and increase payment efficiency/control. Both solutions were implemented through .NET technologies with presentation layers using MPV patterns (with WebForms) and a service layer (using WFC, Entity Framework, Linq, and MSSQL Server), including integration with other third-party services (RUNT - Colombian Single National Transit Registry-, Credit Rating Agencies such as Datacredito, LogTrust)

As a contractor (*Total Time: 40 Months) I provided professional services as Junior (early 2011) and Senior Software Developer for the operation of the SNC-Colombian National Cadastral System-, and related activities like improvements and developments for new functionalities. I developed (with C#, VB.NET and ArcGis Engine) software applications necessary for the geographic module of the SNC. The following artifacts were developed: Desktop Application and Products Server. The desktop application is a component intended to retrieve, create, modify and delete geographic and alphanumeric information related to cities, sectors, terrain, buildings among others. a set of tools designed to make easier the Manage Collective Housing Unit process; an "advanced edition tool-bar", another set of tools intended to draw geographic features in different ways: straight lines, curve segments, points obtained with geometric operations (intersections, unions, projections, among others). The results of this application are delivered via REST webservices allocated and exposed by the SNC. The products server is another component that receives a list of parameters and generates a map with the specifications requested by the user. This is an executable, triggered by a web application which calls upon it.

Implementation and configuration of the Control Version System for the source code of the software in production and development environments using Subversion. The mentioned product manages advertisement in all media. New requirements requested for the clients were implemented according to their needs. A new module for the budgeting process in radio advertising was developed. TThis application was developed as Client-Server; the client side was a Desktop Application written in Java 1.5 and it was integrated with a remote server which was also the database storage.

Consolidation and classification of Geographic Information Databases for differentapplications. For this purpose, we followed the guidelines specified by theOGC OpenGIS Location Services in the document (OpenLS) Core Services(version 1.2). Development application to convert XML to JSON and viceversa. Programming wrapper classes for architecture specification of location-basedservices.
