What I'm looking for

I’m looking to build product-minded, user-focused software at scale—where I can push performance, ship with strong CI/CD, and deliver reliable AI integrations (RAG/agents) with great observability, safety, and cost control.

I’m a full-stack software engineer with 10+ years of experience building scalable web and AI-powered platforms across MarTech SaaS, freelance marketplaces, and esports & gaming. I focus on performance optimization, CI/CD automation, and delivering user-focused software at scale—while staying product-minded and comfortable with “0 to 1” work.

At Contra, I architected a MCP-powered Co-Agent, expanding AI-assisted coverage across core freelance workflows and improving multi-step task completion with agentic workflows (OpenAI, Claude, LangGraph, and context engineering patterns). I also built memory/retrieval architecture with four memory layers (Pinecone, Qdrant, pgvector, Mem0) and strengthened safety, observability, and tool connectivity using MCP-compatible automation and AI infrastructure. Earlier, I engineered a real-time esports tournament platform, improving performance by 25% with Redis caching, async queues, and connection pooling, and delivered React + TypeScript analytics with D3.js.
