Custom Systems Architecture for Enterprises in Ankara
When standard CMS templates collapse: high-concurrency B2B platforms, ERP/inventory synchronizations, local-first desktop-web hybrid systems, and enterprise automation engineered directly by the systems architect.
Most 'custom software' offered by traditional agencies is nothing more than bloated CMS installations wrapped in superficial code. As your enterprise scales, these fragile stacks lock up, query latencies spiral out of control, and proprietary dependencies jeopardize data integrity.
I engineer robust, decoupled applications using TypeScript, Astro, Rust, and .NET 8 that reflect your specific business domain. From the local-first POS networking in oaPOS to high-throughput VoIP recording in oa_sip_recorder and WASM audio/video tooling in 10SeC, I bring proven production rigor to your enterprise systems.
The "Custom Software" Mirage: Why Agency Stacks Accumulate Technical Debt
Hidden Plugin Fragility
Marketed as custom-tailored, projects are chained to dozens of unvetted third-party plugins. A single upstream bug can compromise the entire infrastructure.
Hostage Source Code
Agencies frequently obscure repository access and documentation, forcing clients into predatory hourly maintenance retainers for basic modifications.
Rigorous Systems Engineering
As demonstrated across oaPOS, oa_sip_recorder, and 10SeC: pristine Git history, zero plugin bloat, and clean architecture ready for enterprise IT audit.
Agency "Custom Software" vs. True Systems Engineering
| Domain | Agency "Custom Software" | Onur Aksoy Systems Architecture |
|---|---|---|
| Code Ownership & IP Rights | Proprietary agency lock-in or obfuscated files | 100% client-owned independent Git repo & technical specs |
| Database & Concurrency | Overburdened CMS schemas, severe N+1 bottlenecks | Type-safe, normalized schemas (PostgreSQL / SQLite / Edge D1) |
| Hardware & ERP Integration | Fragile REST mocks; systems halt without Internet | Raw LAN sockets, serial ports (RS232/USB), and deterministic sync |
| Cybersecurity & Governance | Unvetted third-party plugin vulnerabilities | Zero-Trust architecture, granular RBAC, and full OWASP Top 10 compliance |
| Maintainability | Strict agency dependence, undocumented spaghetti code | Clean, industry-standard code navigable by any senior engineer |

Frequently Asked Questions & Architectural Answers
What differentiates your systems architecture from typical agency 'custom software'?
Most local web agencies label their work as 'custom software' while merely packaging off-the-shelf WordPress setups or third-party PHP scripts with superficial CSS tweaks. This inflates database overhead and fails under real production concurrency. I build zero-dependency, bespoke software systems from scratch using TypeScript, Astro, Rust, and .NET 8, tailored specifically to your organization's business logic with zero technical debt.
Who owns the source code and intellectual property upon delivery?
Your organization holds 100% ownership of the entire source code repository, relational database schemas, and architectural documentation. There are no proprietary license lock-ins, artificial framework dependencies, or recurring retainers. Any competent senior engineering team can inspect, build, and extend the system independently.
Can your web software bridge into existing desktop software, ERPs, or local-area hardware?
Yes. Leveraging the local-first socket and IPC patterns I engineered for oaPOS and oa_sip_recorder, I build deterministic bridges between modern web interfaces and on-premise infrastructure. This includes offline-first LAN networks, serial port hardware (scales, barcode scanners, printers), and enterprise ERP databases such as SAP, Logo, or Mikro.
How do you incorporate AI workflows and deterministic automations into business logic?
Rather than treating AI as a superficial customer chat widget, I embed multimodal models into operational pipelines—such as automating order classification, parsing technical procurement specifications, forecasting inventory, and preparing multilingual RFQ responses with deterministic safeguards that eliminate hallucination risks.
How do your architectures comply with enterprise IT and cybersecurity audits?
Every system is constructed to satisfy OWASP Top 10 security standards, strict data protection compliance (KVKK/GDPR), and Zero-Trust principles. With static code auditing, strict Content Security Policies (CSP), and role-based access control (RBAC), the architecture passes corporate IT security screenings seamlessly.
