Senior Delphi Developer for Aviation Software

@vishal1145

Your DevExpress grid performance will degrade once you exceed 50K rows without implementing virtual data mode and server-side pagination. This becomes critical in aviation asset tracking where engine lifecycle datasets grow exponentially. Quick questions - are you planning to migrate this VCL codebase to FMX for cross-platform support eventually? And what's your current Azure DevOps pipeline setup for automated Delphi builds? Here is the architectural approach: - DELPHI/DEVEXPRESS: Refactor legacy VCL forms using DevExpress docking and ribbon controls while maintaining backward compatibility with Delphi 10.x/11 codebases. - MS SQL SERVER: Optimize stored procedures and implement FireDAC connection pooling to reduce query latency in high-transaction engine health monitoring scenarios. - AZURE DEVOPS CI/CD: Build automated unit test pipelines targeting 90%+ coverage using DUnit frameworks integrated with your existing SAFe sprint workflow. I've led similar legacy modernization projects for 2 industrial SaaS platforms that scaled from 10K to 200K records without performance degradation. Let's schedule a technical call to review your current VCL architecture before finalizing the migration roadmap.

Hi, this is the sort of legacy codebase I’m comfortable inheriting—understanding what’s already there before “improving” it. I have 5+ years with Delphi/VCL, DevExpress, Object Pascal, FireDAC/ADO and SQL Server, including production debugging, refactoring and performance tuning. I’m also comfortable with Azure DevOps, Git, CI/CD, Scrum/SAFe and automated testing. For a senior embedded role, I’d suggest ₹2,000–₹3,000/hr or ₹2.5–₹3.5L/month for full-time engagement rather than the posted range. I can commit to the long-term contract and overlap with the client team. Happy to provide a Delphi/DevExpress experience breakdown and discuss the existing codebase.

@bojans9

Hello Hope you are doing well "Maintain And Enhance Legacy Delphi Application" - I can support Delphi VCL development, SQL Server optimization, debugging, testing, and Agile delivery. I can handle feature enhancements, production debugging, root-cause analysis, database optimization, code refactoring, and unit testing within established Delphi applications. I will follow Azure DevOps workflows, collaborate with QA and product teams, document changes, and deliver thoroughly tested maintainable improvements. Could you share the current Delphi version and repository structure for an initial technical assessment? Looking forward to working with you.

@Abror86

Hi, Abror here, from Uzbekistan. I'm a full stack developer with 8+ years of experience working with C#, software development, database programming, and Agile workflows. I understand you need hands-on maintenance and enhancement of a mature Delphi/VCL/DevExpress aviation platform, including production debugging, SQL Server work, automated testing, refactoring, and Azure DevOps delivery. The real challenge is working safely inside an established mission-critical codebase while improving it without disrupting existing workflows. The 90%+ test-coverage target also requires careful regression coverage around legacy behavior. I've worked with enterprise application development, databases, debugging, APIs, and structured development workflows where maintaining existing systems is as important as adding functionality. A few questions to better understand the scope: Q1 - Which Delphi 11/VCL modules need immediate attention? This helps assess the legacy codebase and first sprint scope. Q2 - Which DevExpress components are most central to the application? This clarifies the UI maintenance requirements. Q3 - Is 90% test coverage already measured in Azure DevOps? This establishes the current testing baseline. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you.

Maintaining mission-critical engine management software requires deep Delphi/VCL expertise, rigorous regression control, and robust database optimization. I can integrate seamlessly into your SAFe delivery cycles in Azure DevOps to stabilize, modernize, and enhance your aviation platform. My background spans Delphi 10.x through 11+ Alexandria, developing with DevExpress VCL suites (cxGrid, dxRibbon, Docking, printing/reporting), FireDAC/ADO data access, and MS SQL Server query/stored procedure profiling. my approach: I will tackle backlog epics by isolating legacy technical debt, refactoring Object Pascal routines using the Parallel Programming Library where needed, and profiling T-SQL execution plans to eliminate bottlenecks. I will write DUnitX unit tests toward your 90%+ automation target, maintain traceability in Azure DevOps Git pipelines, and deliver clean architectural documentation. 1. Which Delphi compiler version and DevExpress release is the repository currently pinned to? 2. Are database calls routed primarily through FireDAC or legacy ADO connections? I am ready to help drive reliability and clean engineering across your upcoming Planning Intervals.

@mikes126

This is a legacy-production engineering role, not a greenfield Delphi build — the priority should be making safe changes to the existing VCL/DevExpress application while keeping SQL performance, regression risk and test coverage under control. I’d approach the work around the existing codebase first: understand the Delphi/VCL architecture, FireDAC/SQL Server data layer and DevExpress UI structure, then handle enhancements and production issues without unnecessary rewrites. The areas I’d focus on are: Delphi/VCL feature development and debugging DevExpress grids, forms and reporting SQL Server stored procedures, functions and query optimization FireDAC/database connectivity Root-cause analysis for production issues Refactoring where it improves maintainability without destabilizing working modules Unit testing and regression coverage Git/Azure DevOps workflow and Agile sprint delivery Technical notes and test evidence

@TeraByte26

Hi Shruti, I will deliver new feature development, bug fixes, SQL stored procedures, code refactoring, unit tests and documentation for the existing Delphi VCL/DevExpress desktop app, working within Azure DevOps SAFe sprints.

@melopgabriel

Hi, Legacy Delphi VCL systems often accumulate UI workarounds and slow SQL paths that surface as latency and regressions under production load; the immediate risk is regressions when refactoring without sufficient automated coverage and missing root-cause traceability for engine management flows. I focus on eliminating those pain points first. I have 8+ years working in Delphi desktop applications, maintaining VCL codebases and shipping feature and defect fixes in regulated or safety-adjacent domains. I routinely write and optimize MS SQL Server stored procedures, perform root-cause debugging of runtime faults, and lead code reviews that reduce technical debt. I have hands-on experience with Azure DevOps pipelines and Agile/Scrum delivery, and I regularly convert manual test cases into automated unit tests to approach high coverage targets. I will start by running static analysis and coverage profiling, then add targeted unit tests around engine management transaction boundaries while instrumenting SQL queries for execution plans. That single-cycle focus minimizes risk and produces measurable coverage gains quickly. - Do you have an existing test suite and CI pipeline I can inspect? - Which modules (UI, persistence, or business rules) produce the most production incidents today? Best regards, @melopgabriel

@davitt33

Hi, I’m Davit, a senior software developer with strong experience maintaining and modernizing mature enterprise applications. My background includes C#, ASP.NET, SQL Server, React, Java/Spring Boot, REST APIs, Azure, and large production systems where debugging, performance, database optimization, testing, and safe changes are critical. I’ve worked on legacy modernization and enterprise platforms such as Goyzer, where I maintained ASP.NET/C# applications, optimized SQL Server databases and business workflows, and worked on Azure infrastructure. I’ve also worked on Quicklime, a large production platform using Java/Spring Boot, PostgreSQL, React, Kafka, WebSockets, and Kubernetes, including 400+ test classes, integration testing, and production deployments. One important point: my recent profile does not include professional Delphi/DevExpress development, so I don’t want to misrepresent that experience. However, I’m comfortable working in mature codebases, learning existing frameworks quickly, debugging complex production issues, and following established engineering processes. If Delphi experience is absolutely mandatory from day one, I may not be the right fit. If strong legacy-system engineering and the ability to ramp up quickly are acceptable, I’d be happy to discuss the platform and expectations. Looking forward to our conversation! Best regards, Davit

@naeem1114

Bonjour, je vois que le problème est lié à la maintenance et à l'amélioration d'une application Delphi/VCL legacy. Je pense que l'un des défis est de gérer les interactions entre les composants DevExpress et les packages Delphi, et je m'approcherais de cela en utilisant des outils de débogage pour identifier les problèmes de performances. Je vais également utiliser mon expérience avec FireDAC pour optimiser les requêtes SQL Server. Je pense que l'un des pièges courants dans ce type de projet est de négliger l'importance de la refactorisation du code legacy pour améliorer la maintenabilité et les performances, et je suis prêt à commencer immédiatement en utilisant mes compétences en Delphi et en DevExpress pour résoudre les problèmes de production et améliorer l'application.

@eugabrielmaximo

Hello, Your engine management platform needs someone who can work safely inside a mature Delphi/VCL codebase — fixing production issues, improving performance, and adding features without disrupting mission-critical workflows. I understand this is not a greenfield project. The key challenges are maintaining legacy Object Pascal code, working deeply with DevExpress VCL and SQL Server, improving test coverage, and delivering reliably within an Azure DevOps/Agile environment. My approach would be * First understand the existing architecture, dependencies, and highest-risk areas. * Trace production issues to root cause before implementing fixes. * Improve SQL queries/stored procedures and refactor high-impact legacy code incrementally. * Strengthen automated unit coverage around critical business logic while keeping sprint delivery predictable. I can also share my Delphi version history, specific DevExpress components, and relevant modernization/migration examples. If useful, I’d be happy to start with a small codebase assessment or discuss one of your current technical pain points.

@shaynegg

Hi, I like this project because working on a mature Delphi/VCL system requires careful changes without breaking proven production workflows. I’ve worked with Delphi, Object Pascal, VCL, DevExpress, FireDAC and SQL Server on legacy desktop applications, including debugging, refactoring and database optimization. For this platform, I’d first understand the existing architecture and critical workflows, then handle enhancements with unit tests and regression checks. I can also optimize stored procedures and queries, investigate production issues through root-cause analysis, and keep changes traceable through Git/Azure DevOps. I’m comfortable working inside Agile teams with QA and product stakeholders, while documenting design and test evidence. Which Delphi version is the current production codebase using, and which DevExpress modules are most heavily used?
