Hire the Best Visual Basic Programmers
in the United States

AVAILABLE NOW! I have a Finance MBA, Project Management Professional Certification (PMP), and over 15 years of data analysis, data modeling, conversion, and building models, analytics, and dashboards using MS Excel and VBA. I also work with Google Sheets for data analysis and reporting. My focus is on Data Conversions, Dashboards, and Automation. Over 400 clients on Upwork have been happy with my work.

I’m a senior Excel VBA developer with 29 years of corporate-level experience automating spreadsheet processes, enhancing productivity, and modernizing legacy applications. My clients have included MassMutual, The Hartford, Pratt & Whitney, Connecticut Children’s Medical Center, CVS/Health, and more than 85 Upwork clients. For Cornerstone Real Estate Advisers (a MassMutual subsidiary), I developed a suite of proprietary budgeting tools that saved the firm over $1 million in commercial software licensing fees. The suite of asset-type-customized workbooks ran successfully for two decades and was widely preferred to commercial software alternatives across a user base of 100+ property management companies in the U.S. and Canada. Excel VBA is my specialty. I build and code robust automation solutions, eliminate time-consuming manual tasks, and stabilize unstable or error-laden workbooks. I also integrate Excel with Word, Outlook, and other MS Office applications for data-driven document generation and communication workflows. With advanced writing skills and an editor’s keen eye, I deliver top-shelf documentation. I write clean VBA code that is easy to follow, maintain, and troubleshoot, using a style refined over nearly three decades—far more readable, efficient, and maintainable than typical auto-generated macro code. I'm experienced collaborating with professionals in finance, accounting, engineering, and actuarial science—delivering tools that streamline operations, enhance decision-making, and stand the test of time. I favor a structured, incremental development process—guided by clear communication and steady progress toward the right solution. My goal isn’t just to deliver working code—it’s to create lasting value, delivered clearly, with precision and purpose.

My goal is to provide solutions that meet or exceed my clients' expectations. I have a B.S. in Computer Science and a Minor in Mathematics. I have developed applications and scripts using over a dozen programming languages, and specialize in working with data. I am an Excel/Access expert and can automate these applications. I have worked with relational databases, including Microsoft SQL Server (2005, 2008R2, 2014, and 2017). I have reporting and data visualization experience using SSRS, Excel and Tableau. Additionally, I have experience working with APIs, Google Sheets, and App Scripts. I welcome any requests, big or small.

My name is Martin Gruszka, I am an experienced, solution oriented, systems programmer. I code VB, VBA, T-SQL, C#, and ASP Dot Net. I have deep familiarity with Microsoft Access in the Enterprise and Microsoft SharePoint as a Document Management and Automation platform. I design and integrate database systems, deploy data transformation solutions, migrate companies to new platforms, design new processes, project manage vendors and initiatives. I have developed a keen sense and understanding of the underlying Business Practices that these technologies tend to support. Particularly solutions impacting the non-profit world but also membership management, sales, and accounting. Working with me you'll find articulate, highly technical yet business oriented, professional, always seeking a win win, and able to present technical concepts to business audiences and vice versa. Let's connect! I program primarily in - T-SQL - ASP Dot Net - C# - Python - VBA - Visual Basic - JavaScript I have direct experience implementing on top of the following platforms: - MS Access - MS SharePoint - Dynamics CRM, AX, SL - DotNetNuke - MemberTrack - MS SQL Server - SQL Server Integration Services (SSIS) - SQL Server Reporting Services (SSRS) - Azure SQL Server

I build and maintain VB.NET Windows Forms applications with SQL Server and Microsoft Access backends. With 35+ years of experience, I handle the full stack — systems analysis, database design, stored procedures, UI development, and API integrations (Salesforce, Stripe, QuickBooks). I specialize in custom line-of-business applications where off-the-shelf software doesn't fit. Recent projects include a $50M+ factoring management system, a SaaS tax collection platform used by ~100 municipalities, and an emergency response system for FEMA/Travelers Insurance. I am also currently finishing up work on a software application that landscapers and other similar businesses can use to run their businesses. I like to use DevExpress DXperience controls extensively to create beautiful, feature-rich user interfaces and reports. I also migrate legacy Access/VB6 systems to modern .NET platforms. I excel at being able to come up with innovative, efficient, and user-friendly software solutions and at breaking down complex problems into smaller, more easily understood ones. I pride myself in writing well-organized and easily understandable code, emphasizing object-oriented principles, thereby creating code that is much easier to maintain, for myself and others. I am a clear communicator and a thorough analyst. MS Electrical Engineering | BS Industrial Engineering
