What I'm looking for

I’m looking to lead teams building cloud-native, AI-driven finance platforms—combining AWS microservices, CI/CD, and GPU-accelerated forecasting. I want responsibility for end-to-end architecture, reliable delivery, and measurable business outcomes.

I’m a Technical Lead & Senior Software Engineer with 10+ years building cloud-native, AI-driven finance and enterprise systems. I’m known for turning complex requirements into scalable roadmaps, end-to-end delivery, and measurable business value.

As Technical Lead at 1TPLUS, I aligned stakeholders and teams to deliver an AI-powered centralized quantitative trading agent. I designed AWS environments for high availability and compliance, built CI/CD using AWS CodePipeline, and implemented Saga-based microservices for transaction consistency and fault tolerance.

I specialize in low-latency, event-driven systems—connecting exchanges and integrating blockchain features via RPC/provider APIs. I also lead product-grade UI delivery with Flutter, crafting user-centric, cross-platform experiences backed by robust microservice architectures and serverless patterns.

Beyond production systems, I work as a Data-driven Quantitative Trading Analyst, training LSTM/GRU models for forecasting with CUDA acceleration and integrating TradingView alert webhooks through a Golang execution engine. My background also includes DevOps and solution architecture across Kubernetes/GitOps, Kafka event streaming, and deep observability with Dynatrace and Kibana, supported by an AWS Certified Developer – Associate certification.
