EXPERIENCE

Tech Lead & System Architect — Collective Forecast
Feb 2025 – Present · AI-driven market analytics platform (CoFo AI)
Led architecture and delivery of a high-load financial analytics ecosystem, managing a cross-functional team of 10+

inception to production launch
– Engineered a real-time ingestion layer (WebSockets, Redis) processing exchange data streams with sub-second
latency under sustained load
– Built a production LLM pipeline: Chain-of-Thought reasoning with dual-stage fact-checking and retrieval over a vector
database (Qdrant) for verifiable AI-generated insights
– Supervised an ML team delivering Scout 2.0, a proprietary model for trend-strength and market-phase classification
– Implemented infrastructure as code: Kubernetes on AWS + Alibaba Cloud, Terraform, CI/CD — reducing release cycles
from days to minutes
– Ran hiring and technical interviews; established code-review standards and mentored engineers across the stack
AI City Guide (second product delivered within the company)
– Agent-based conversational assistant for travelers — place discovery, route optimization, personalized day plans (React
