About me

I'm Felix, a freelance senior product engineer with 8+ years of experience building web applications and running production systems. I'm looking for remote freelance/B2B contracts, especially SaaS development, greenfield products, and modernization projects where I can own delivery from application code through deployment.

Recent work

- Developed Go-based Kubernetes operators to automate deployment, configuration, and lifecycle management of IAM/PAM components, including Zitadel.

- Migrated a production Magento platform from on-premises hosting to GCP/GKE, including containerization, database replication, observability, and cutover preparation.

- Stabilized enterprise applications on OpenShift, improved CI/CD and GitOps delivery, and integrated Entra ID SSO into TypeScript services.

- Built the ALDI deals frontend from scratch with React, Next.js, and TypeScript, including API integrations and production deployment on Azure Kubernetes.

- Helped customers integrate AI coding tools and development workflows into their repositories.

i let 4 different agents review the same dirty code base (200+ files changed, c++, game engine):

- deepseek v4.1 flash via deepseek API: took 20m to find one p1 issue that was relevant and a p2 issue that was irrelevant

- glm 5.3 flash NVFP4 via TP2 DGX Sparks: took 1h 5m to find a p3 documentation issue

- gpt 5.6 sol: took 5m30s for one p1 and one p2 issue. both relevant

- gpt 6.1 sol: took 4m30s for two p1 and one p2 issue. both relevant.

Worth to mention: none of those findings overlapped.

I let deepseek v4.1 flash and gpt 6.1 sol both plan fixes for the summary of the findings. in this particular scenario: gpt 6.1 sol planned to increase a buffer size from 128 to 256 to fit the 191 elements that blew past a test scenario. it included some headroom. deepseek v4.1 flash on the other hand decided to make it exactly 191 to satisfy the test, for example.

The TPS decode on deepseek is impressive. I never had a second / feeling of being left aone and though "damn this thing is working". Despite all my efforts, it took ~4x longer in a review, found less and planned worse than GPT 6.1 Sol. Wall clock time. I don't have token counts for comparison. If I were to grade those models from 1-10 (10 = top tier GG), I'd give deepseek a solid 6.5 and 6.1 sol a 7.5-8.0 maybe.

Interesting, why is this spam or off topic? This is absolutely an AI topic that needs to be discussed. Not off-topic. Moderation? Hello?

it's 500$ for 25x the plus usage, thats pro (max).

this implies that the old 200$ 20x pro (more) is now more like 10x the usage of plus.

they are slashing our subscriptions in half and make it "but we're more efficient!"
