C# Programmer for Futures Trading Program automation in Quantower using Quantower Algo
It was great working with Yuriy. His experience programming trading software came through as he completed the projected earlier than I had anticipated and he deeply understood what was meant/required by the requests I made. I thought I was clear/explicit in my instructions, but when I saw his documentation, I was blown away. Not only is Yuriy an excellent programmer, I would bet he is an excellent trader as well - and in my opinion, that is the best combination. Yuriy did some extra things beyond the scope of the project - to help me out or to tighten things up - which I really appreciated. He is my go to person on future trading programs. Highly recommended!

.NET Full Stack Developer Needed for the Tour Management Application
Working with Yuriy from Altura Codeworks was a great experience. He delivered clean, efficient code and integrated seamlessly into our system. Communication was smooth, tasks were completed on time, and the results exceeded expectations. I’d gladly recommend him for any C#, Angular, or backend development work.

Job Success
Sokilnyky, Ukraine - 1:43 am local time
My strongest areas are .NET/C#, ASP.NET Core, Angular, React, TypeScript, SQL databases, API integrations, and AI-assisted workflows. I usually work on systems where correctness, maintainability, and business logic matter: fintech, compliance, CRM/workflow platforms, document-heavy applications, legacy modernization, and internal operational tools.
Recently, my focus has been on AI-enabled SaaS and workflow automation: document ingestion, RAG-style search, structured AI outputs, audit trails, evidence handling, policy/document generation, and integrations with third-party systems. I’m also building AlturaQuantera, an AI/compliance SaaS product, so I understand both the engineering and product side of early-stage SaaS development.
What I can help with:
• Full-stack SaaS development with .NET, Angular, React, TypeScript, PostgreSQL, SQL Server
• Backend architecture, REST APIs, background jobs, integrations, and complex business logic
• AI integrations using OpenAI / LLM APIs, document workflows, RAG, structured outputs, and automation
• Compliance, fintech, CRM, document-processing, and internal workflow systems
• Legacy application modernization, refactoring, performance tuning, and system stabilization
• Database design, reporting, import/export workflows, and integration layers between SaaS tools
• Production readiness: authentication, RBAC, audit logs, logging, testing, deployment, and maintainability
• Multi-tenant SaaS architecture, user roles, permissions, subscription logic, and admin dashboards
• API integrations with third-party platforms, webhooks, payment systems, CRMs, data providers, and automation tools
• Data-heavy applications with complex forms, tables, dashboards, filters, workflows, and reporting
• AI-assisted document search, summarization, classification, extraction, and review workflows
• Clean Architecture, layered architecture, domain modeling, and maintainable service boundaries
I’ve worked on systems ranging from financial platforms and CRM-like internal tools to industrial/network monitoring software and AI-assisted compliance products. I’m comfortable joining existing codebases, understanding messy business logic, and improving systems without unnecessary rewrites.
Typical problems I solve:
• “Our prototype works, but it is not production-ready.”
• “We need a senior engineer to clean up architecture and stabilize delivery.”
• “We need AI features, but not a fragile GPT wrapper.”
• “Our business workflow is trapped in spreadsheets and manual processes.”
• “Our legacy .NET / Angular / SQL system needs modernization.”
• “We need API integrations, data imports, dashboards, permissions, and reliable backend logic.”
• “We have complex documents and need AI-assisted extraction, search, or review.”
• “We need a maintainable SaaS architecture before the product becomes too messy.”
• “We need a technical partner who can think through product logic, not just write code.”
I have experience across backend and frontend development, including ASP.NET Core APIs, Web API, Entity Framework, Dapper, SQL optimization, Angular applications, React dashboards, TypeScript frontends, background workers, file processing, scheduled jobs, authentication, authorization, and deployment workflows.
I also work with AI and automation in a practical way: LLM APIs, OpenAI API, embeddings, pgvector-style search, RAG pipelines, structured JSON outputs, prompt/version management, document workflows, and human-in-the-loop review. I focus on making AI features traceable, testable, and useful for real business users — not just impressive demos.
Additional relevant domains:
Financial dashboards, forex/FX systems, market-data workflows, economic data APIs, reporting dashboards, document intelligence, compliance automation, CRM/workflow platforms, data imports, ETL-style pipelines, scheduled jobs, and AI-generated structured insights.
