Eliminate AI regressions before deployment by hiring senior freelance AI engineer Aldian Fazrihady to build deterministic LLM-as-a-Judge CI/CD evaluation suites. With 15+ years of full-stack software engineering experience, Aldian Fazrihady partners directly with CTOs, VPs of Engineering, and technical founders via Upwork and direct B2B consulting contracts.

1. Production Architecture: Automated LLM-as-a-Judge & Deterministic Regression Testing in GitHub Actions

Hiring a senior freelance programmer requires verifiable production patterns rather than generic boilerplate. Below is a battle-tested implementation pattern used in high-availability systems:

from dataclasses import dataclass
from typing import List

@dataclass
class EvalCase:
    case_id: str
    prompt: str
    expected_facts: List[str]
    forbidden_phrases: List[str]

def score_deterministic_assertions(output_text: str, case: EvalCase) -> float:
    lowered = output_text.lower()
    for phrase in case.forbidden_phrases:
        if phrase.lower() in lowered:
            return 0.0
    matched = sum(1 for fact in case.expected_facts if fact.lower() in lowered)
    return matched / max(1, len(case.expected_facts))

2. Key Engineering Guarantees

• Golden Dataset Benchmarking: Curating 200+ real-world production edge cases with ground-truth facts, tool-call expectations, and latency SLAs.
• CI/CD Pull Request Gating: Failing GitHub Actions builds automatically if faithfulness, factual recall, or JSON schema adherence drops below 98%.
• Cost & Latency Drift Detection: Tracking token usage and time-to-first-token (TTFT) across model upgrades (OpenAI, Claude, Gemini).
