High-Performance Backend APIs
RESTful and GraphQL APIs in Rust, Node.js or Python; low latency, high concurrency. OpenAPI/Swagger documentation is our standard.
Custom Software Development
Custom Web and Backend Solutions
Enterprise-grade custom web applications, SaaS platforms and high-performance backend APIs that place your digital product on a scalable, secure and sustainable foundation.
At Sora Yazılım, instead of off-the-shelf templates we design custom web applications and backend systems that map one-to-one to your business processes. From SaaS platforms to enterprise admin dashboards, from B2B portals to real-time data APIs, we build end-to-end solutions across a wide spectrum.
We approach every project with an architecture-first mindset: we build the infrastructure to be scalable from day one so that you keep the same performance even when your user base grows tenfold. We apply modern patterns such as microservices architecture, event-driven communication, caching and database sharding as your needs require.
We make sure every line of code we write is secure, tested and observable. Protection against OWASP Top 10 vulnerabilities, JWT/OAuth2-based authorization, GDPR-compliant data management, structured logging and distributed tracing are standard parts of every project we deliver. Working hand in hand with our DevOps and infrastructure management service, we make release processes seamless.
Whether you need an API integration into your existing system, a modernization of a legacy stack, or a SaaS platform built from scratch, our team owns the entire journey — from the discovery call to post-launch support.
Choosing the right technology is a critical decision that drives roughly 40% of a project's long-term success. At Sora Yazılım, Rust (Axum) is our choice for financial systems requiring high concurrency and low latency; Node.js + TypeScript for SaaS products that need fast iteration and a wide ecosystem; Python (FastAPI) for AI-heavy or data-intensive ETL workloads. In every decision we focus on an architecture that won't pile up technical debt five years from now.
Process transparency is the single factor that most distinguishes Sora Yazılım from other agencies for our enterprise clients. We hold a live demo at the end of every two-week sprint and give you real-time visibility into progress through a shared backlog (Linear or Jira). Living technical documentation in Notion, Architectural Decision Records (ADR) and reasoning behind each call are always available to you. Weekly check-ins and a monthly executive report are included for projects without surprises.
Turkey-based team advantage: local time zone, GDPR/KVKK and Turkish Commercial Code expertise, native Turkish/English communication and the option to meet face-to-face when needed. We eliminate the time-zone gaps, cultural disconnects and compliance risks common with offshore agencies — while delivering 40–60% cost advantage versus US/EU rivals with senior-level engineering quality.

Our Approach
We bring your project to life in 5 steps
From the first conversation to post-launch support, we run a transparent, measurable and feedback-friendly process.
- 01
Discovery & Analysis
In a free discovery call we listen to your business goals, existing systems and constraints. The output: a detailed scope document and a proposal.
- 02
Architectural Design
We prepare a technical design document covering the data model, service boundaries, authentication flow and infrastructure options — then validate it with you.
- 03
Sprint-Based Development
We ship features in two-week sprints to a production-like staging environment. Every sprint ends with a demo and feedback loop.
- 04
Testing, QA and Go-Live
We minimize release risk and move to production with automated tests, load tests, security scanning and canary deployments.
- 05
Monitoring and Continuous Improvement
We watch system health with metrics, logs, alerts and monthly performance reports. SLA-based support packages are available.

Frequently Asked Questions
Common questions about custom web and backend development
If you can't find your question below, use the form to send it through and our team will get back to you within 24 hours.
How is this different from a template-based website?
Template solutions offer limited functionality and quickly become insufficient as you grow. The custom software we build is designed to fit your business processes exactly; it scales, integrates with your third-party systems and delivers long-term cost advantages.
Which backend language and framework do you choose?
There isn't a single right answer — we choose based on the project's needs. For systems requiring high concurrency and low latency we lean toward Rust (Axum), for MVPs that need fast iteration Node.js, and for ML- or data-heavy projects Python (FastAPI).
How long does a typical project take?
A focused MVP can go live in 6–8 weeks. For complex SaaS platforms we plan between 3 and 6 months. After the first discovery call we share a concrete scope and timeline proposal.
Can you integrate with our existing software?
Yes. We can connect to your existing ERP, CRM, e-commerce or accounting software via REST/GraphQL APIs, message queues or direct database integration. For migrations from legacy to modern systems we follow a phased modernization strategy.
Do you provide maintenance after go-live?
Yes. We offer monthly SLA-backed support packages: bug fixes, performance improvements, security patches and new feature development. Our DevOps team keeps the infrastructure side under continuous watch.
How is data security ensured?
OWASP Top 10 controls, AES-256 encryption for sensitive data, secret management for environment variables (Vault/Sealed Secrets), penetration testing and GDPR-compliant personal data retention policies are core parts of every project.
Do I retain ownership of the code?
Yes. All source code, documentation and deployment configuration belongs to you. We develop with commit access to your repositories; you can take ownership and hand it to your own team at any time.
How do you coordinate with our existing team?
Daily communication via Slack/Discord/Teams, weekly sprint review/planning, a shared Jira/Linear backlog and living technical documentation in Notion. We adapt to the processes you already have.
Do you run scalability tests?
Yes. Before going live we run load tests with k6 or Gatling, measuring how the system behaves at three times the target traffic. We report and fix bottlenecks upfront.
How is the software cost calculated?
For fixed-scope projects we offer a turnkey proposal; for continuous development we provide a monthly team capacity model. After the first discovery we recommend, free of charge, the model that fits you best.
Do you also manage the hosting side?
Yes. We design, deploy and operate on popular infrastructure such as AWS, Hetzner, DigitalOcean, Cloudflare Workers and self-hosted Coolify. If data residency requires the data to stay in Turkey, we offer local data center options too. Evaluate this together with our DevOps service.
How does your DevSecOps pipeline work?
Every commit passes through automated unit + integration tests, OWASP ZAP security scans, Trivy container image vulnerability checks, SonarQube code quality analysis and a dependency vulnerability check. Canary deployment rolls new features to 5% of users first; if metrics are stable, traffic ramps to 100%.
Can you integrate AI capabilities?
Yes. We integrate OpenAI, Anthropic Claude or self-hosted Llama/Mistral models into your existing backend: RAG (retrieval-augmented generation), agent frameworks and vector databases (Qdrant, Pinecone, pgvector) for building intelligent assistants. See our AI/LLM integration service for a deeper look.
Do you use open source or proprietary stacks?
We are open-source first and favor MIT, Apache 2.0 and BSD-licensed projects. When stickier licenses such as AGPL aren't a fit for a commercial product we run a license-compatibility audit. We transparently report license risks; if commercial choices (Oracle DB, etc.) are required for cost or technical reasons, we advise accordingly.
Can you clean up technical debt in our existing software?
Yes — we run dedicated incremental modernization projects. Phase one is a code quality + security audit (~1 week), followed by a critical-debt prioritization matrix, then parallel refactoring sprints while production keeps running. A typical 5-year-old monolith can be moved to a modular architecture in 3–6 months without downtime.
