I am a Senior Software Engineer and Technical Consultant with 25+ years of hands-on experience delivering enterprise software, database and data-migration solutions, ERP customizations, system integrations, Windows desktop applications, and workflow automation. I help clients solve technically complex problems involving business systems, data, APIs, legacy applications, and production environments. My core areas of specialization are: • Oracle NetSuite Development & Integration SuiteScript 1.0/2.x, RESTlets, Map/Reduce, User Event and Scheduled scripts, SuiteTalk SOAP/REST, SuiteFlow, Saved Searches, CSV imports, third-party integrations, production troubleshooting, and legacy-script migration. • Database Development, SQL & ETL Microsoft SQL Server, PostgreSQL, Oracle, DB2, SQL Anywhere, MySQL, Firebird, SQLite, and 4D. I work with database design, SQL/DDL development, stored procedures, data migration, ETL, data conversion, reporting logic, performance troubleshooting, and production issue resolution. • Delphi / Object Pascal Development RAD Studio, VCL, Windows desktop and client/server applications, Windows Services, database applications, multithreaded systems, legacy-code modernization, debugging, refactoring, and ongoing product maintenance. • AI-Assisted Development & Workflow Automation n8n, API and webhook integrations, scheduled workflows, OCR and AI-assisted data extraction, database-backed automation, automated reporting, email/SMS notifications, Telegram workflows, and AI-assisted modernization of existing software. Selected results from previous projects include: • Authored and reworked more than 70 NetSuite SuiteScript solutions for a large ERP implementation. • Developed REST APIs and data-migration interfaces connecting NetSuite with Salesforce, MuleSoft, payment systems, banking APIs, and third-party logistics services. • Delivered dozens of SQL, DDL, ETL, and PowerShell solutions for healthcare, property-tax, insurance, education, and enterprise data-migration projects. • Migrated business-critical Oracle PL/SQL logic to PostgreSQL for financial commission calculations and daily reporting. • Delivered more than 100 improvements and bug fixes for Delphi-based transportation and healthcare applications. • Improved a C# and SQL Server document-printing solution, reducing recurring printing costs by approximately 20%. I also have deep specialist experience in smart cards, JavaCard/JCOP, GSM SIM/USIM, PC/SC, APDU processing, cryptography, OpenSSL, Microsoft CryptoAPI, digital signatures, and security-oriented software. I can work across the full software-development lifecycle: requirements analysis, architecture and technical design, implementation, database development, integration, testing, deployment, documentation, production support, and root-cause troubleshooting. My approach is structured and practical: I clarify goals, study the existing system, identify risks early, communicate progress clearly, and deliver solutions that are maintainable—not merely quick patches.
