Balaji S.
Fintech & AI Systems Engineer, based in Dublin
Dublin, IrelandBalaji is a full-stack engineer and AI systems developer with two years of production experience across fintech, telecoms and AI. He holds an MSc in Computing (AI) from Dublin City University, First Class Honours.
Most recently, as founding engineer at a Dublin fintech trading platform, he built the company's investment platform solo: client portals, a payments microservice handling Bank of Ireland and SEPA Instant integrations, and a PostgreSQL ledger with full regulatory audit trails, all live in production today. Before that, he worked on manufacturing-scale infrastructure supporting a $900 million national telecoms contract, and built internal cloud automation tooling at a global consulting firm.
Sector experience
Fintech and payments, telecoms and manufacturing infrastructure, regulated financial systems with audit-trail requirements.
AI systems work
Builds regularly with LangGraph, MCP tool servers, and RAG pipelines, routing across multiple frontier models with automatic failover. Placed 2nd at the AWS Global AI Hackathon Ireland 2025 and 3rd at HackEurope Dublin, and completed MSc research on deep learning model optimisation, including a custom GPU pipeline that cut inference time by over 75%.
Case studies
Multi-agent orchestration platform (Greenlink)
Built Greenlink, a multi-agent platform using AWS Bedrock for telecom network optimisation, with autonomous decision-making and human-in-the-loop checkpoints. Placed 2nd at the AWS Global AI Hackathon Ireland 2025, judged by senior leaders from Intel and Meta against 45 teams and 377 participants. This shows capability in autonomous multi-agent orchestration with built-in human oversight, applicable to clients automating complex operational decisions where compliance, safety or accountability require a human checkpoint before action is taken.
High-throughput blockchain infrastructure (Solana Agent Kernel)
View SAK →Built the Solana Agent Kernel, a high-performance in-memory execution pipeline in Rust that processes raw bytecode streams against a 2,000-plus policy matrix in under 50ms using concurrent async channels. Built as part of Vouch AI, a decentralised reputation platform that took 3rd place at HackEurope Dublin 2025 against 1,000+ builders across Dublin, Paris and Stockholm. This shows capability in high-throughput, low-latency systems and Web3 infrastructure, applicable to clients exploring blockchain-based verification, smart contracts or decentralised business processes.
AI-powered DeFi lending protocol (VouchAI)
An AI-powered DeFi lending protocol that issues under-collateralised loans and dynamic asset-backed guarantees by turning on-chain history and Web2 developer identity into a quantifiable, MiCA-compliant Trust Score. When a user connects their wallet:
- Identity aggregation: fuses their Web3 financial history with their Web2 proof-of-work and Solana Name Service (.sol) domains.
- AI underwriting: an LLM evaluates this data to clear the wallet for EU MiCA Anti-Money Laundering compliance and generates a definitive Trust Score (300-850).
- Dynamic pricing: the AI instantly generates a personalised Loan-to-Value and risk matrix.
- Programmatic escrow: users pledge collateral into a secure Rust-based protocol vault, instantly triggering an automated loan disbursement.
