Software Architecture
I translate business problems into solid architectures: distributed systems, event-driven design, high concurrency, and documented decisions (ADRs).
Hi, I'm

Software Architect · Full-Stack (Node.js · React · Cloud)
I design and build scalable systems end-to-end — I pick the right tool for each problem, not the other way around.

01 — About
Polyglot architect, not a single-stack specialist
I have 6+ years shipping production software across Node.js, Java/Spring, .NET, React/Angular, and agentic AI systems. My value isn't in one technology: it's in translating business problems into solid architecture, without marrying a tool.
Today I design AI agent orchestration platforms covering the full development lifecycle — built on the principle that AI proposes and humans approve. Before that, I built Java microservices for nationwide-scale operations and complete full-stack platforms from scratch.

Where I add the most value
Backend & Microservices
APIs and microservices in Node.js, Java/Spring Boot, and .NET — with service discovery, queues, and messaging to scale with isolated failures.
Frontend
Interfaces in React, Next.js, and Angular with high-polish, responsive, accessible UI, wired to real APIs.
Cloud & DevOps
AWS infrastructure (EC2, S3, RDS, Lambda, VPC, IAM), Docker, CI/CD with Jenkins and GitHub Actions, and IaC with Terraform.
Agentic AI
Multi-agent systems in production: LLM orchestration, MCP servers, and agents with human control by design.
Security
Robust authentication and authorization: OAuth 2.0, JWT, RBAC, and careful handling of sensitive data.
03 — Work
Selected work
Current role · NDA
NDAAI Agent Orchestration Platform
AI agent orchestrator covering the full development lifecycle — from client requirement to delivery. A central runtime (supervisor + router) on top of an event bus, with per-agent task queues to isolate failures and parallelize work, and agents organized by domain: intake, build, quality, and deploy/ops.
Key decisions: central router vs. peer-to-peer communication; event bus to decouple stages; human checkpoints defined by permissions — agents propose, humans approve.
Impact ↗Reduced architecture iteration cycles; process adopted organization-wide.

Current role · NDA
NDADevelopment Agent: Feature to Merge Request
An agent that receives a feature request via chat and delivers a review-ready merge request. Includes a scope pre-check with an efficient model, an "interrogation" phase that narrows the requirement before executing, and path safety that prevents operating outside the workspace.
Design principle: "AI implements, but never merges alone" — control through permission architecture, not trust in the model.

Current role · NDA
NDAMCP Connector for SaaS Platform
MCP (Model Context Protocol) server exposing tools from a messaging/collaboration platform (mail, docs, sheets, tasks) so an LLM can invoke them safely, with auth, token, and rate-limit handling.
Lesson learned: a good MCP is 80% tool interface design and error handling.
