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, a deterministic orchestrator for CLI coding agents: reproducible runs, signed audit trail. 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.
