Lead development of the Zigma360 software stack (SaaS, Azure cloud, Android, IOS) and contributed to many different areas of the software.Key achievements (in chronological order):● Designed and implemented Backup System (databases and files) for long-term storage with an admin panel.● Lead the design and implementation of bookkeeping subsystems (invoicing, payments, reconciliation, WIP/ inventory accounting).● Implemented Plan Stock Production and Plan Purchase To Stock system which collects and analyses all active sales and production projects and makes proposals for production or purchasing respectively for a specific date so that a manager can plan in advance all processes within the company. The key factor here is speed and accuracy, and to achieve this goal, the declaration of the product in the registry has been reviewed and optimised, which has played a fundamental role in other parts of the Zigma360 product.● Built an infrastructure for direct payment processing (Nets, Telepay, ISO 20022), later enhanced to support Pre-approved payment files (BankId for Payment Initiator identification and ASiC container to package payment files along with approval data) to comply with Anti Money Laundry act §13.● Developed e-invoicing and EDI (electronic data interchange) infrastructure meeting the requirements of the PEPPOL standard.● Designed and implemented Data extraction and recognition of PDF invoice documents to automate process registration of incoming invoices in the system (language-specific rules and template matching).● Designed and developed Document Centre - a centralised place for processing all incoming and outgoing electronic documents (e-invoicing, order, catalogue, payment).● Implemented integration layers with multiple external systems (Visma, Xledger, UniEconomic, SveaFinance, HuldtLillevik, SAF-T)● Exposed the server with RESTful api to communicate with our mobile application, as well as to be open for integration with external parties.

Joined the company at an early stage of development of Zigma360 product (a complex ERP system) and led software engineering efforts in most critical components:● Designed and implemented Multi-Tenant Architecture based on database separation (each client has its own database). It gives freedom to clients to have their own database settings regarding speed and reliability.● Implemented from scratch Email Synchronization Service to send / receive emails.● Designed and implemented Assembly Framework - framework to describe various stages of assembling a product, with ability to customize assemblies with built -in C# scripting. This opens up extensive opportunities for product customization before ordering.● Developed Document Management Framework to manage various documents which handle relationships between processes, inventory, accounting, and other subsystems.● Technologies used: Microsoft Azure cloud platform, .Net Framework 4.0, WCF, Remoting, NHibernate, WinForms GUI, DevExpress components.

● Designed and developed OCR Engine with Machine Learning using LeNet-5 Convolutional Neural Networks, a finite-state transducer (FST), image processing.● Implemented highly robust web service to expose the OCR recognition engine able to cope with high load of client requests.● Gained good understanding of Neural Networks and other AI technologies, raised low-level networking skills.

● Took part in development of a phone- and online-based survey system (ASP.NET, PostgreSQL). The introduction of the system has significantly reduced the company's costs by reducing the use of paper questionnaires and face-to-face interviews.● Implemented various UI tools and data analysis tools for the Analytical Department and Department of Field Research.
