I’m a Senior Software Engineer and Technical Lead with 16+ years of hands-on experience building, modernizing, integrating and supporting business-critical web applications. My strongest experience is in complex enterprise systems where software is closely connected to real business processes — including e-commerce, order management, warehouse management, inventory, purchasing, POS, CRM and multichannel sales. I work across both Microsoft .NET and PHP ecosystems and can take a project from understanding the existing system and business requirements through architecture, development, integration, performance optimization, modernization and deployment. My core experience includes: • ASP.NET, ASP.NET MVC, ASP.NET Core, .NET Framework, WebForms and Web API • PHP, Laravel and modern web development • JavaScript, jQuery, React, Vue.js, HTML/CSS and AJAX • SQL Server, T-SQL, MySQL, database design, stored procedures, indexing and query optimization • REST, SOAP, GraphQL, webhooks and third-party API integrations • Event-driven and asynchronous processing • Legacy application modernization and incremental migration • Software architecture, system design and technical decision-making • Code reviews, technical specifications and development-team guidance • Performance analysis and optimization at application and database level I have extensive experience integrating enterprise systems with platforms such as Shopify, Magento, WooCommerce, Fortnox, Visma, Business Central, Ongoing Warehouse, Jira, Tempo, Upsales, Microsoft 365 and Google Cloud/BigQuery. A significant part of my work has involved modernizing large existing systems without disrupting day-to-day business operations. For example, I designed and implemented a hybrid migration approach for a major ASP.NET WebForms system, allowing existing WebForms functionality to remain operational while functionality was gradually moved toward ASP.NET MVC. I also work hands-on when a problem is difficult. When a performance, architecture, database or integration problem requires deeper investigation, I prefer to understand and solve the underlying problem rather than simply work around the symptoms. I can work as a senior individual contributor, technical lead, or as the technical lead for a development team when a project requires broader ownership. If you have an existing application that needs modernization, a complex integration that needs to work reliably, a performance problem that has been difficult to solve, or a new business system that needs experienced technical direction, I can help assess the situation and determine the most practical way forward.

I help businesses get their operations out of people's heads and into systems that actually work — through SOPs, process maps, and workflow documentation that stick. My background includes pharmacy benefits analytics at Xevant and enterprise healthcare data work at Change Healthcare — which means I understand operations at a level most freelancers don’t. I’m also currently engaged as a Business Analyst on a large-scale enterprise consulting project (details under NDA), leading discovery, risk and bottleneck analysis, process improvement, and user story development — so this isn’t just past experience, it’s live, current work. I help businesses fix both sides of the problem: building clean data systems and the process documentation to make them actually stick. What I help with: — SOPs and workflow documentation — Process mapping and bottleneck analysis (Lucidchart) — Workflow audits with prioritized recommendations — Excel & Access dashboards, trackers, and databases — Cross-functional coordination and operational reporting I offer fixed-price catalog projects for SOPs, workflow audits, and operations starter packs — so you know exactly what you're getting before we start. I work fast, communicate clearly, and deliver things that get used. Based in Maine, available across US time zones. If that's what you need — let's talk.

What does a Stored Procedure Development specialist do?

A stored procedure development specialist writes and maintains server-side code that runs directly inside a database management system. This role moves data-processing logic from application servers into the database layer to reduce network traffic and enforce consistent business rules at the source. The specialist authors procedural SQL scripts that accept parameters, execute complex queries, and return structured results or status codes to calling applications. They manage the full lifecycle of these database objects from initial design through debugging and final deployment to production environments.

  • The specialist authors stored procedure definitions using Data Definition Language statements such as CREATE PROCEDURE or ALTER PROCEDURE in the target SQL dialect. They define input and output parameters to control how data enters and leaves the routine while implementing conditional logic loops and error handling within the procedure body. This work requires precise syntax knowledge for specific platforms like Transact-SQL for Microsoft SQL Server or PL/SQL for Oracle databases to ensure the code compiles and executes without errors.
  • They debug procedural code by running test executions against sample datasets within integrated development environments like SQL Server Management Studio or Oracle SQL Developer. The specialist inspects variable states traces execution paths and validates that output parameters match expected values under various conditions. This process identifies logical flaws performance bottlenecks or unintended side effects before the code reaches live users who depend on accurate data retrieval and modification.
  • The specialist packages verified procedure definitions into deployment-ready SQL scripts that database administrators can run safely in staging and production environments. They coordinate with team members to manage schema permissions and roles required for creating or altering these objects without disrupting existing application connections. This step includes documenting changes to procedure signatures and behavior so other developers understand how to call the updated routines correctly in their application code.

How to hire a Stored Procedure Development specialist on Upwork

Step 1: Post a job

Define your database environment and logic requirements clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your needs in a few sentences, and Uma constructs a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing post.

  • Specify the target SQL dialect, such as Transact-SQL for SQL Server or PL/SQL for Oracle, so freelancers know which syntax to apply.
  • List required database objects, including specific stored procedures, functions, or triggers that need creation or modification.
  • Detail performance expectations, such as query execution time limits or concurrency handling needs for high-traffic applications.

Step 2: Evaluate candidates

Look for proof of complex server-side logic implementation in past projects. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review process.

  • Review DDL scripts in their portfolio to verify clean parameter definitions and proper error handling within procedure bodies.
  • Check for experience with specific IDEs like SQL Server Management Studio or Oracle SQL Developer to ensure workflow compatibility.
  • Confirm they document procedure dependencies and permissions, which indicates a mature approach to database security and maintenance.

Step 3: Interview your top choices

Discuss technical approaches to data integrity and deployment safety. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session.

  • Ask how they debug complex procedural logic and validate output parameters against expected results during development.
  • Request examples of how they manage schema changes and coordinate deployments across staging and production environments.
  • Explore their method for optimizing slow-running queries inside stored procedures without breaking existing application calls.

Step 4: Agree on scope and begin work

Set clear milestones for script delivery and testing validation. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Define deliverables as version-controlled SQL scripts that include both CREATE and ALTER statements for easy updates.
  • Require test execution artifacts that demonstrate correct behavior with sample data inputs before final acceptance.
  • Establish a review process for code quality, focusing on readability, commenting, and adherence to your database naming conventions.

Frequently asked questions

Is hiring a Stored Procedure Development specialist worth it?

For most businesses, yes: hiring a Stored Procedure Development specialist is worthwhile. These experts move complex data logic from application code into the database layer, which reduces network traffic and centralizes business rules. They write optimized SQL that executes faster than client-side processing for large datasets.

How do I evaluate Stored Procedure Development specialist candidates?

Review their approach to error handling and parameter validation within procedure bodies. A strong candidate writes code that checks input types before execution and uses try-catch blocks to log specific failure reasons rather than letting the database return generic errors.

What tools do Stored Procedure Development specialists use?

Specialists use database-specific integrated development environments like SQL Server Management Studio or Oracle SQL Developer to write and debug code. They also rely on command-line interfaces to execute DDL statements such as CREATE PROCEDURE directly against test databases.

Do Stored Procedure Development specialists handle database deployment?

Yes, they package procedure definitions into version-controlled SQL scripts for safe promotion across environments. This workflow ensures that changes to procedure logic apply consistently from development servers to production systems without manual editing.
