Hakan A.
Last position:
Senior Software Engineer — AI Evaluation & Benchmarks at Diversido
- Provided technical leadership for a 4-engineer team delivering 3 major client platforms in 12 months with microservices architecture and scalability solutions — 100% of scoped majors shipped ahead of schedule vs. planned milestones (baseline: prior releases often slipped 1–2 sprints).
- Ran AI model evaluation and model outputs evaluation on LLM/AI vendor APIs: safety, completeness, instruction adherence, and groundedness review before go-live; cut escaped bad outputs in AI-integrated release checklists from recurring UAT findings to near-zero on final promote.
- Drove API development and performance optimization for payment, exchange, and AI services; fail-closed error handling and payload validation reduced integration rework cycles by ~35% vs. the first AI integration pass.
- Applied software testing, testing frameworks, code quality assurance, and code refactoring with continuous integration gates; first-pass PR acceptance improved across the team and production hotfixes on AI adapters dropped noticeably after review standards landed.
- Owned DevOps practices: Docker, GitHub Actions, Jenkins-compatible pipelines, and version control workflows — cut deployment time ~50% vs. pre-automation baseline and stabilized releases across 3 client environments.
- Implemented verifier/oracle-style pass-fail checks in container sandboxes (Harbor/Terminal-Bench aligned); wrote technical documentation so failures cleared in one review cycle.
- Led cross-functional collaboration with product and client stakeholders; translated AI evaluation scores and risk findings into plain-language briefs for non-technical partners, unblocking go/no-go decisions without extra engineering meetings.
- Used agile methodologies for sprint planning and backlog ownership; mentored engineers so mid-level contributors owned AI adapter modules independently by mid-engagement.

About the technology
Traffic control
Rate limiting controls how many requests a client, user or service can send within a defined period. It protects APIs and backend systems from overload, abusive automation and accidental traffic spikes. Policies can apply by IP address, API key, user identity, route or tenant.
Algorithms
Common approaches include token bucket, leaky bucket, fixed window and sliding window. Each handles bursts, fairness and storage differently. Strong implementations return clear response headers, consistent error messages and a retry path that client applications can follow.
Tools and integration
Rate limiting can run in an API gateway, reverse proxy, service mesh, application layer or edge network. Specialists often work with NGINX, Envoy, Kong, HAProxy, Redis, cloud API gateways and distributed caching. They connect policy decisions with authentication, observability and deployment workflows.
Where it fits
- Public REST and GraphQL APIs
- Partner and multi-tenant platforms
- Login, search and checkout endpoints
- Event-driven services and webhooks
- Edge traffic and bot protection
In Germany, companies across software, manufacturing, financial services and online commerce use these controls to keep shared services stable while preserving access for legitimate clients.
When expertise helps
- Traffic patterns change after a launch or campaign
- A distributed system needs shared limits across regions
- Gateway rules conflict with application behavior
- Customers report unexplained throttling
Freelance expertise is useful when a team must design policies, migrate gateway rules, tune Redis-backed counters or investigate production incidents. Remote collaboration usually works well, while on-site workshops can help with complex platform changes.
Quality signals
Strong professionals understand both protection and user experience. They test burst traffic, clock differences, race conditions, fail-open and fail-closed behavior, and limits across replicas. They also document exceptions, monitor rejected requests and explain how policies affect clients.
Look for experience with distributed systems, HTTP semantics, authentication, caching, dashboards and infrastructure as code. The best specialists can turn business rules into transparent controls without hiding capacity problems behind aggressive throttling.
Frequently asked questions
Questions about Rate Limiting? Start with the answers below.
Rate Limiting controls request volume so an API or service remains available under normal, bursty or abusive traffic. It is used for public APIs, authentication endpoints, partner access, multi-tenant systems, webhooks and expensive operations such as search.
Rate Limiting restricts request frequency over a time window, while quotas cap consumption over a broader period and concurrency limits control work running at the same time. A reliable design may combine all three because they solve different capacity and fairness problems.
A strong Rate Limiting specialist should understand API gateways, reverse proxies, Redis or another shared store, authentication, HTTP response headers and observability. Distributed systems, Kubernetes, infrastructure as code and incident analysis are also valuable when policies span several services.
For a simple gateway rule, focused Rate Limiting experience may be enough. Distributed policies, tenant-specific limits and high-impact production changes require someone who has tested bursts, replication behavior, failure modes and client communication in comparable systems.
Yes. Rate Limiting design, configuration, testing and monitoring can usually be handled remotely through shared repositories, dashboards and controlled environments. On-site sessions may help when access controls, legacy infrastructure or several German teams need coordinated workshops.
Rate Limiting at the gateway gives broad protection before requests reach services, while application-level controls can use business context such as account tier or operation cost. Many systems use both, with clear ownership to prevent conflicting policies and confusing client responses.
A sound Rate Limiting design explains its keys, windows, burst behavior, storage model and failure policy. Test results should cover concurrent requests, distributed instances, clock issues, retries, exemptions and observability, with response headers that help clients adapt.
Before working on Rate Limiting, a specialist needs traffic patterns, service limits, client identities, gateway topology and the consequences of rejecting requests. Access to logs, dashboards and a safe test environment makes it possible to validate policies without disrupting production users.
