I am a Microsoft Certified Professional. If you’re not impressed by my certifications, how about Top Rated Plus and 100% Job Success on Upwork? Still feeling picky? I warmly invite you to explore my work history below, where you’ll find feedbacks from my clients and successful real-life projects they’ve commented on directly on the platform. My professional experience with Microsoft Dynamics 365 Business Central and its predecessor, Microsoft Dynamics NAV, covers more than 12 years. I can implement Business Central for your company or take over your half-implemented solution from an unreliable partner. WANT TO GAIN MORE EXPERIENCE WITH BUSINESS CENTRAL, TRAIN YOUR USERS, AND AUTOMATE THEIR DAILY ROUTINES IN THE SYSTEM? I'm ready to consult your team and share my experience in configuring and operating Business Central in the following areas: financial accounting (chart of accounts, account payables and receivables, bank reconciliation, fixed assets, intercompany transactions, financial consolidation), supply chain management (distribution, warehousing, replenishment), manufacturing and retail (LS Central, LS Nav, LS Hospitality, LS Forecourt from LS Retail). LACKING SOME FEATURE IN BUSINESS CENTRAL OR STRAGGLING FROM IRRITATING ERRORS? With my technical background, I can easily troubleshoot errors, customize the standard functionality to your needs or industry-specific requirements, create bespoke features or modules from scratch, and develop new reports and document templates matching your company's corporate style and identity. I am also experienced with and implemented numerous integrations between Business Central and other on-prem systems and online services (Dynamics 365 for Sales, Magento, InforWM, Quantum Qguar, custom web, and mobile apps, etc.). INTERESTED IN BUILDING YOUR COMPANY'S BUSINESS INTELLIGENCE AND ADVANCED REPORTING? I can help you to expose your Business Central's data to Power BI. Together we can design reporting solutions that can answer questions from your specific business domain or niche, which is not possible with off-the-shelf Power BI reports. Moreover, little or none of such reports can effectively mine Business Central's data, as it requires a deep understanding of the internal data model, while also respecting established data consistency rules. Please do not hesitate to contact me to discuss your upcoming implementation project or desired modifications. I will be more than happy to share my experience and knowledge with you! Looking forward to hearing from you!
