I've placed highly in many worldwide trading competitions in various asset classes, have a decade of experience in Futures & Options, including at a leading OMM firm, top Hedge Fund, and have managed a mid size prop fund for past ~5 years -- I do this because I simply love new challenges, and love building strategies.

That is all that you will receive, from me or any professional. ** I DO NOT work in Tradingview; It is not an automation platform, and live results vary too drastically to be considered a reasonable backtesting / prototyping platform. ** I DO NOT work in MetaTrader 4/5, because there are better frameworks, platforms, and implementations for any given use case. ** I RARELY accept unknown clients, none for small one off tasks. It’s simply not worth it / too unpredictable.

Fintech AI specialist building production RAG, agents, MCP integrations, and ML features for B2B fintech SaaS companies. 100% Job Success Score, $50K+ earned, clients in the US, UK, and EU. I lead BlueSoft, a small senior team focused exclusively on AI engineering for fintech. Most of my work has been in the same domain — retrieval over financial documents, agents that touch ledger and transaction data, ML models for fraud, risk, and underwriting decisions. What I see fintech teams wrestle with most when shipping AI: A RAG system that's fluent on demo questions and starts hallucinating once it hits a real document corpus — clauses with footnotes, amendments overriding earlier sections, tables that lose meaning when chunked the standard way. In a regulated context that's not a UX bug, it's a compliance incident. An agent with broad tool access that's one prompt away from making a write call nobody can audit — and a CTO who has no way to prove the action graph is bounded. An underwriting or fraud model that performs well in evaluation, then drifts quietly in production. The drift surfaces months later, after a quarter of decisions have already gone out the door. These aren't edge cases. They're the default conditions of shipping AI in regulated finance, and they shape every architecture decision I make from day one. What I typically build: - RAG over financial documents — pitch decks, 10-Ks, loan files, compliance archives - Multi-agent systems for finance operations — underwriting orchestration, KYC/AML triage, claims processing - MCP integrations connecting LLMs to ledger, ERP, CRM, and core banking systems - LLM features inside existing fintech products - Machine learning (ML) models for fraud, risk, and underwriting How I work: - Discovery, architecture, and technical reviews run by me directly — I'm an engineer first - Evaluation harnesses (Ragas / DeepEval) wired into CI before any pipeline ships - Observability from day one (LangSmith / Arize Phoenix) — traces and failure-mode dashboards visible to your team Stack: Python, LangGraph, Claude Agent SDK, OpenAI/Anthropic APIs, vector databases (Pinecone, pgvector, Weaviate), Postgres, AWS/GCP. Comfortable plugging into existing stacks rather than imposing new ones. If you're a fintech CTO, VP Engineering, or technical founder weighing an AI build or integration — RAG over your docs, an agent for an ops workflow, an ML model for a credit or fraud decision — let's scope it on a short call — I'll give you a straight read on what it takes.
