Siaka Cargos
Founder & Principal Engineer — Full-Stack & Automation Architecture
Engineered an end-to-end system of record to replace fragmented, manual freight logistics processes — a centralized automation layer that ingests raw operational data, eliminates manual cross-checks, and closes the gaps where human auditing fails.
Developed an automated document extraction pipeline that parses unstructured invoice fields, cross-checks the data against a vector-indexed rate index, and flags compliance overcharges automatically — eliminating line-by-line manual review.
Built a deterministic scoring engine that aggregates multi-source data streams — cargo asset values, customs hazmat status, live port congestion metrics — to categorize shipment risk tiers dynamically, ahead of operational bottlenecks.
Orchestrated an asynchronous LLM agent pipeline, Claude wired through n8n, to run carrier lookups, apply contract reconciliation rules, and sync structured execution data straight into the CRM.
Tax Liability Engine
Founder & Principal Engineer — Core Microservices & Pipeline Orchestration
Designed and deployed a self-hosted transactional engine for accounting and CFO firms that need their data to stay inside their own infrastructure — centralizing webhooks from every major payment gateway into a single, idempotent ledger to track state-by-state sales tax nexus automatically.
Normalizes chaotic webhook payloads from Stripe, PayPal, Shopify, and Adyen into one consistent ledger format, with strict duplicate-event protection at the database write path so network retries never double-post a transaction.
A tiered pipeline — fast local cache, then deterministic rules, then a Claude fallback for ambiguous product classifications — with an atomic claiming mechanism that keeps parallel workers from racing on the same event.
Computes a continuous rolling 12-month revenue metric against each state's legal threshold, surfacing an early warning before a nexus is officially crossed rather than a notice after the fact.
Automation & Workflow Systems
Production-grade microservices built to orchestrate data flows and eliminate manual overhead.
AI Inbound Receptionist
Orchestrated an autonomous voice pipeline on Retell AI and Twilio to handle customer intake, process live calendar bookings through n8n, and log post-call telemetry straight to a central CRM.
Multi-Channel Job Matching Bot
Built a cross-platform bot on WhatsApp and Telegram that ingests raw CV files, scores candidates against open roles with pgvector semantic search, and triggers automated M-Pesa payment distributions.
Video Clip Factory
Engineered a headless media pipeline that processes long-form video, uses AI transcription to identify high-impact segments, and programmatically cuts and renders optimized social clips.
Computer Vision Bot
Implemented a real-time object detection service on YOLOv8 and OpenCV to track physical entities across live streams, converting visual frames into structured data for downstream automation.
