Need an experienced Microsoft Access/VBA developer to fix, enhance, automate, modernize, or take over an existing business-critical application? I bring around 15 years of software development, application support, requirements analysis, client handling, and technical leadership experience, with deep hands-on expertise in Microsoft Access, VBA, SQL Server, Salesforce, .NET, and business process automation. My core specialization is Microsoft Access and VBA. I have extensive experience working with complex and long-established database applications, including systems containing large numbers of forms, queries, reports, VBA modules, integrations, and business rules. I am particularly comfortable taking over existing applications — even older systems with limited documentation — understanding how they work, resolving problems, implementing new requirements, and improving them without disrupting existing business processes. MY CORE SERVICES ✅ MICROSOFT ACCESS & VBA • Microsoft Access database/application development • VBA programming and automation • Forms, reports, queries, macros, and modules • Legacy .mdb and .accdb application maintenance • Debugging and troubleshooting existing Access systems • Multi-user database applications • Complex reporting and data processing • Performance optimization • Access front-end with SQL Server back-end • Excel, Outlook, Word, PDF, HTML, and email automation • Import/export automation using Excel, CSV and external data sources ✅ SQL SERVER & DATABASE DEVELOPMENT • Microsoft SQL Server development • Complex SQL queries • Stored procedures and views • Data transformation and reconciliation • Database migration • Access-to-SQL Server integration • Reporting solutions • ETL and data-processing workflows • PostgreSQL and MySQL experience ✅ SALESFORCE I also have substantial Salesforce development, administration, migration, and production-support experience, including: • Apex Classes and Triggers • Batch Apex • SOQL and SOSL • Visualforce • Salesforce Administration • Workflows and automation • Sandbox-to-Production deployments • Data Loader • Salesforce org-to-org migration • Merging Salesforce instances • Salesforce data replication to SQL Server • Unit testing and code coverage • Production support and maintenance ✅ .NET & APPLICATION DEVELOPMENT Additional development experience includes: • VB.NET • ASP.NET • Windows Forms • JavaScript • ADO.NET • Client-server applications WHY CLIENTS HIRE ME My work is not limited to writing code. I work with clients to understand their actual business process, analyze existing systems, identify the root cause of problems, design practical solutions, implement changes carefully, test them, and provide ongoing support. I am a particularly good fit when: • You have an existing Access/VBA application that needs an experienced developer • Your original developer is no longer available • You have a legacy database with little documentation • Access needs to work with SQL Server • Complex VBA or SQL code needs troubleshooting • Manual processes need automation • Reports, PDFs, emails, Excel files, or data exports need to be automated • An existing application needs modernization rather than complete replacement • You need ongoing application maintenance and support • Your project involves Access, SQL Server or Salesforce technologies If you have an existing system that needs development, troubleshooting, modernization, migration, integration, or ongoing support, send me a brief description of the requirement. I can review the problem and recommend a practical approach.
