John Sessford

I specialize in complex problem solving, support escalations and root-cause analysis, and in leading the technical response when production problems are hardest to resolve.

I have more than twenty years in enterprise software and telecommunications, including twelve at Salesforce, where I progressed from Tier 3 engineer to Senior Success Architect.

Research

Outside work I publish open-source research through Ikailo: Entroptics, signal analysis that reads structure from the data itself, applied to language-model context, model weights, inference, radio and astronomy.

The older repositories below are earlier prototypes, kept as history.

Pinned Loading

  1. Agience/entroptics Agience/entroptics Public

    The universe, in focus. Find the real structure in noisy multichannel data, with no rank to choose and no threshold to tune.

    Python 2

  2. Agience/entroptics-frb Agience/entroptics-frb Public

    Fast radio burst morphology recovered from CHIME/FRB data with an untuned read. Reproduce and verify the results.

    Python

  3. Agience/agience-mantle Agience/agience-mantle Public

    The Agience substrate: one SQLite file and a content-addressed store, opened in-process.

    Python 1

  4. Agience/entroptics-rf Agience/entroptics-rf Public

    A radio physical layer that is detectable as energy, not as a signal: blind acquisition and a keyed waveform on commodity SDRs.

    Python

  5. Agience/entroptics-context Agience/entroptics-context Public

    Language-model context read as the subspace it resolves: how many retrieved items to keep, which one is injected, whether an answer stayed on its sources.

    Python 1

  6. Agience/entroptics-mass-gap Agience/entroptics-mass-gap Public

    The Yang–Mills mass gap as a finite-resolution effect: paper, Lean 4 development and analysis code.

    Lean 2 1
