Full-Stack & AI-Agent Systems Engineering

Crafting scalable systems with Clean Architecture & AI Integration.

Software Engineer specializing in high-throughput backend architecture, resilient systems, and modern web applications. Bringing engineering discipline and failure-resilient precision from an electrical/electronics background into scalable Golang (Fiber, GORM) systems engineered with Clean Architecture and Modular Monolith principles, paired with type-safe React/TypeScript frontends. Actively developing agentic AI workflows, contextual RAG with vector databases (Qdrant), and LangGraph multi-agent systems built for real-world production.

How I Work

Structured flow from problem framing to production system.

01

Discovery & Success

Goals, technical constraints (scale, latency, budget), and measurable criteria.

02

PRD & System Specs

PRD, SDD, database schema / ERD design, and type-safe API contracts.

03

Build & Verification

Clean architecture, safe concurrent modular code, and automated testing.

04

Handover & Telemetry

Zero-downtime deployment, handover documentation, and log observability.

What I do

Building scalable, secure, and maintainable full-stack systems.
