Bio

Andrii is a senior Salesforce engineer who's been building custom solutions using the Salesforce platform for the last 13 years. This involves coding classes, batches, scheduled classes, email handlers, triggers, Visualforce pages, and adding and customizing standard and custom objects. Andrii mainly works on integration solutions but thinks business needs should be sourced from end users (those who will use a feature or an executive).

Experience

Appuri

A software company with several Salesforce components that are manually created and configured in their client's organizations. I made unmanaged and managed packages that were installed with minimal configurations from the client's side.

Project and Invoice Management

I created a series of Visualforce pages to ease project and invoice setup and management. Initially the process was processed manually by setting up everything manually by a user (like create a bunch of records for each week to bill a customer). Now you can customize it—by settings dates, by the number of invoices for a project, and some other details. It has a manager setup project and invoices, and accountant set billed hours/sums (after this an invoice is sent to an external billing application).

Organization Administration

It has various capabilities for fields modifications, record types, workflow/validation rules, layout changes, installation/removing applications, and adding/modifying/removing users.

JC

I built a series of custom Apex REST API web services to manage data from desktop WPF and mobile iOS applications.

Test Case Manager | C#

https://softina.com

I built a WinForms application to manage test cases. I created the test cases, ran them, and saved the test results. Data was stored in an MS SQL database and shown in a tree view on the application.

FSM

This is a case management system with specific company rules. It has Visualforce pages with minimal JavaScript and CSS. The back-end logic is in the controller/extension, it has PDF generation, and saves as an attachment (implemented via a Visualforce page rendered as a PDF) plus external web services.

OPP

This is an opportunity management system with specific company rules. It has Visualforce pages with minimal JavaScript and CSS, back-end logic in the controller/extension, and external web services. I recently did an organization restructuring. That included modifying fields and their values with new organization structure model, code (including external web services), workflow rules modifications, and documenting all the changes.

Project Tracker | Flex

https://softina.com

I created a project management system that was initially written in PHP. I then added Flex forms to it instead of HTML forms. The challenge was to replicate PHP-generated HTML/CSS/JS with Flex and connect it with the PHP back end.

Ginmon GmbH (via Toptal) | Research

A company decided to use Salesforce for managing communications with customers. I was hired to integrate Salesforce into the company's software for managing communications with customers; an integration was needed with company's software. I tackled this problem by beginning to investigate how an integration could be made between the two systems for the specific Salesforce functionality. I also provided documentation of how to make the needed features work.

IG - Deposit Invoice

I automated deposit invoice generation based on sales orders. I created new Aura dialogs to streamline the user interface, built a Visualforce page to render invoices as PDFs, and added fields to capture extra details. I also set up triggers to recalculate values dynamically using the new fields.
