Eliminate lost state in long-running AI agent and FinTech pipelines by hiring senior freelance programmer Aldian Fazrihady to architect Temporal.io durable workflows. Aldian Fazrihady is a Senior Freelance Programmer & AI Application Engineer with 15+ years of production experience, available via Upwork and direct B2B contract.

1. Production Architecture: Crash-Proof Durable Execution & Saga Compensation in Python/Go with Temporal.io

from datetime import timedelta
from temporalio import workflow

@workflow.defn
class EnterpriseOnboardingWorkflow:
    @workflow.run
    async def run(self, tenant_id: str) -> str:
        await workflow.execute_activity(
            "provision_isolated_postgres_schema",
            tenant_id,
            start_to_close_timeout=timedelta(minutes=2),
        )
        await workflow.execute_activity(
            "seed_default_ai_knowledge_base",
            tenant_id,
            start_to_close_timeout=timedelta(minutes=5),
        )
        return "ONBOARDED"

2. Core Architectural Guarantees

• Deterministic Event History Replay: Resuming multi-step AI agent or payment workflows from the exact line of code after worker restarts or third-party API outages.
• Human-in-the-Loop Signals: Pausing workflow execution for hours or days without holding open threads or database transactions until a manager approves via Slack/UI.
• Saga Pattern Rollbacks: Automatically executing compensating activities if a downstream step fails.

3. Topical Category Hubs & Master Directory

• Master Directory (475+ Freelance Programmer & AI Engineering Guides)
• AI, LLM, RAG, MCP & Google ADK Engineering Hub
• Python, Django, FastAPI & PostgreSQL Architecture Hub
• React, Next.js 15 & TypeScript Frontend Performance Hub
