Upswell runs on live Git telemetry, ranked peer attestations, and a double-blind trust layer you control. Built for the working engineer, not the platforms farming them.
AI hiring tools scrape the same public data and repackage the keywords as a fit. Volume went up. Signal didn't. Upswell runs on live Git telemetry and peer attestations behind a double-blind trust layer: signal AI can't fabricate, and you never have to prove.
You're not drowning in candidates. You're drowning in candidates AI qualified for you.
It scored the words. You still have to find out if the engineer behind them can ship.
Your public work is training data for tools you never opted into.
Scraped, ranked on stars and followers, and repackaged into a “profile” that isn't yours. Nothing about you exists on Upswell until you put it there.
Control your technical passport.
No form-filling, keyword optimization, or ghosting. Your Build Pass verifies your real-world technical signature straight from your Git log while keeping your identity fully private.

Infra and AI heavy, light on frontend. Product sense is the gap, this role wants more of it than I have.
Fine-tuning pipeline for a 7B-parameter LLM, shipped to production in six weeks, solo.
4 attestationsEnd-to-end model stack (training, eval, serving) owned solo across two teams.
3 attestationsCut p99 inference latency from 800ms to 90ms via batching and kernel fusion.
3 attestationsllm-eval-harness, 800+ GitHub stars, still the internal source of truth.
2 attestationsRebuilt the training data pipeline to cut a 14-hour job down to 40 minutes.
2 attestationsRan the GPU cost review that took monthly spend from $48k to $19k.
Seven years, two AI startups, both pre-Series A. I owned ML infra at both: data pipelines, training, eval, and serving. No separate platform team, so I built and ran all of it. Cut inference latency 9x on a team of three. Wrote the eval harness both companies still use to gate model releases. Before that, three years on a platform team doing on-call for other people's services.
Looking for a small team where I can take on the full path from experiment to production. Most of the hard work happens after training: serving, evals, cost, and keeping it up, and that's the part I'm good at. Happy to be the person who handles it so the rest of the team can stay on the model. Staff level, remote, seed or Series A.

Has shipped production ML training pipelines end to end, not just notebooks.
HARD GATEHas operated low-latency model serving under real production load.
HARD GATEHas built and owned an LLM evaluation harness other engineers rely on.
HARD GATEHas debugged distributed training and GPU performance issues in production.
HARD GATEHas owned infrastructure cost and capacity decisions, not just consumed them.
preferredHas worked without a platform team to hand the tedious parts to.
preferredWe build the model training infra layer for next-gen ML pipelines, from data ingestion through low-latency serving. You'd own training infra, eval harnesses, and the serving pipeline from experiment to production. Third ML infra hire, reporting to the CTO. Scope is wide and a fair amount of the tooling is still half-built.
Own the eval harness end to end. Ship the first fine-tuned model to production. Define the serving SLA with the CTO, and help hire the next two infra engineers.
Series A raised 8 months ago. Platform team scaling from 2 to 6 as usage climbs past capacity planning every quarter.
Infra and AI weighted, frontend out of scope. Needs some product judgment, you pick what gets built.
