    Bilingual AI Coaching Platform Architecture Review

    • Python 3.12
    • FastAPI
    • LangGraph StateGraph
    • Claude/GPT/Gemini
    • Pinecone
    • PostgreSQL
    • SSE

    A bilingual AI psychological coaching platform needed an independent review of its LangGraph therapy engine before widening pilot access. The main risks were session state integrity, retrieval quality, safety boundaries, and streaming reliability.

    Voice AI Production Architecture Assessment

    • LiveKit Agents
    • Deepgram Nova-3
    • GPT-4o-mini
    • Cartesia Sonic-2
    • Twilio
    • FastAPI

    A restaurant voice ordering platform needed an independent assessment of their production voice AI system; costs were higher than expected and latency was inconsistent.

    Multi-Model AI Investment Council

    • Python
    • Claude Opus
    • GPT-4o
    • Gemini Flash
    • FastAPI
    • Vue 3
    • Docker

    A Dubai-based investment firm needed a structured way to stress-test investment decisions using multiple AI perspectives simultaneously, without relying on a single model's reasoning.

    Qdrant Hybrid Search RAG Pipeline

    • Qdrant
    • BM25
    • RRF fusion
    • cross-encoder reranking
    • FastAPI
    • Python

    Dense-only vector search missed keyword-exact matches; BM25-only search missed semantic intent. Neither was production-ready for a document Q&A use case with both precision and recall requirements.

    Silverlight to WebAssembly Migration

    • Silverlight
    • OpenSilver
    • Blazor WebAssembly
    • ASP.NET Core
    • Entity Framework

    A US parts distribution company had a critical business application built on Silverlight, EOL since 2021, blocked by Chrome and Edge security updates, no longer accessible without plugins.

    Integrating a Third-Party AI Judgment API into a Production Triage Pipeline

    • Python
    • REST API integration
    • regression testing
    • empirical API verification

    A high-volume triage pipeline needed an independent AI "second opinion" layer on top of a rules-based prefilter, but a paid AI judgment API is not plug-and-play: vendor docs can misdescribe a score's real scale, and a client-side safety check can misread the vendor's own billing model and silently drop capacity already paid for.
