questions people ask before they email. plain answers. if a section says "not the right fit" — believe it.
who is alex
alex chernysh. AI engineer in israel — retrieval, evals, agent infra. open-source side is bernstein, an orchestrator for CLI coding agents. writing lives here.
the bot speaking as "i" is the same person. with citations.
what does alex actually work on
three surfaces. bernstein — open-source, runs on real repos. an AI engineering role with production traffic. forward-deployed consulting for teams whose live system needs cleaner seams.
is alex available for consulting
yes, for the right shape. forward-deployed before full-time. send a paragraph on what you're running to alex@alexchernysh.com — proposed scope comes back the same day.
what's alex's technical background
several years of production systems before AI; the AI work is the last few. each post on the blog grew out of something that broke. publication date ≈ when the fix landed.
how does alex think and work
deterministic where you can, LLM where you must, calibrated everywhere. evals are gold sets, not vibes. a retriever that confidently returns wrong context is worse than one that says "i don't have this".
patterns where others see noise. the ordered systems are mine; the world stays its own chaos.
what's the writing on alexchernysh.com about
retrieval grounding, eval discipline, agent infrastructure, safety that isn't theatre. failure-mode-driven. the kind of thing i wish someone had handed me before i ran into it.
how to reach alex
email — alex@alexchernysh.com. a paragraph on what you're running and where it hurts.
what alex does outside the work
sound production, mostly. instrumentals, beats, jazz/blues sketches — chernysch on soundcloud. no marketing, no claim to seriousness. → soundcloud.com/chernysch
past life: music editor at FM stations (broad audience) and programming director at a TV channel (a notably narrower one). the contrast taught pacing.
what is alex NOT
shapes where the answer is "not the right person":
- delegating evals away. evals are the job.
- full-time or unusual offers — email alex@alexchernysh.com. the bot's diplomacy budget is small.
- marketing or fundraising. honest-engineer voice; growth-marketing would be the wrong author.
- prompt workshops, fine-tuning gigs, RAG-as-a-service. real disciplines; mine is the production-systems-around-them layer.
