Turn agent runs into OpenTelemetry spans, block prompt injection with information-flow control, and swap model providers behind one Agent API.
Turn Microsoft Agent Framework agent runs into OpenTelemetry spans, block prompt injection with information-flow control, and swap model providers behind one Agent API.
There's a job that most engineers have never heard of and that many would actually enjoy: the sales engineer, or presales engineer — the technical expert who partners with salespeople to win technical deals. It's where deep technical knowledge meets customer-facing work, where you help customers solve real problems with technology rather than writing code all day, and where an engineer who can also communicate becomes genuinely rare and valuable. If you've ever wondered how technical products actually get sold to technical buyers, this role is a big part of the answer.

A working guide to Python's scalar types — arbitrary-precision integers, IEEE-754 floats and the 0.1 + 0.2 trap, when to reach for Decimal and Fraction, the operators that surprise you with negatives, why a boolean is secretly an integer, and how truthiness and None actually work.

How Go's declaration forms, scope rules, and its unusual constant system fit together — including the untyped-constant model that makes numeric literals feel effortless, and the `iota` patterns that turn enums and bit-flags into a few tidy lines.

How a network authorizes on the issuer's behalf when the issuer host is unreachable — and how the books get squared afterward.
How the network authorizes on the issuer's behalf during downtime using stand-in rules and limits, then reconciles advices when the issuer returns.
When software holds the card and clicks "buy," the old questions — was this the cardholder, did they mean to, who pays if not — all get harder to answer.
The new fraud surface: prompt injection turning a shopping agent into an attacker's buyer, hijacked delegated credentials (Visa saw ~450% more dark-web 'AI Agent' chatter in H1 2026), and disputes when an agent acted on…
Model days-past-due transitions, SMA/NPA classification, provisioning triggers, and cure logic as one deterministic engine driven by time and repayment events.
Teaches how to model delinquency as a state machine: days-past-due bucket transitions, SMA/NPA classification rules, provisioning triggers, and cure/roll-forward/roll-back logic driven by repayment events.
How to assemble features from bureau, bank, and alt data, serve a scorecard or model, apply policy cutoffs, and emit adverse-action reason codes with a full audit trail.
Teaches how to build a decisioning engine: feature assembly from bureau/bank/alt data, scorecard vs ML model serving, policy rules and cutoffs, and adverse-action reason-code generation with an audit trail.
How to ingest watchlists, match names across scripts and spellings, and turn a fuzzy score into an auditable clear, alert, or block.
Teaches how to build sanctions/watchlist screening: list ingestion (OFAC/UN/EU), transliteration and fuzzy name matching, scoring thresholds, whitelisting, and rescreening on list deltas to control false positives.
When you want fixed control flow, don't ask the model — wire it yourself.
Sequential, Parallel, and Loop agents compose sub-agents in fixed patterns — deterministic orchestration where you, not the model, decide control flow, with state flowing between steps.
How to snapshot a running workflow at every super-step, then throw the instance away and rebuild a fresh workflow that resumes from a saved checkpoint.
A cyclic guess-the-number workflow snapshots state each super-step, then a brand-new workflow instance is rehydrated from a checkpoint via ResumeStreaming.
Wrapping an agent run with async seams that log, time, guard, and short-circuit — without touching the agent's logic.
Wrapping an Microsoft Agent Framework agent run in Python with async middleware seams — timing, logging, and a guardrail that short-circuits a tool call before it runs.
