Profile

I am an experienced Technical Lead and Technical Architect with a background in building and scaling high-load platforms, designing robust system architectures and leading cross-functional teams through complex projects.

My engineering focus is backend and full-stack development with PHP, Node.js, Go, Python and C#, plus databases, distributed systems, data pipelines and AI-assisted engineering workflows. I have delivered large-scale data migrations, ML-driven content search and recommendation services, AI/automation workflows and frameworks that improve release confidence and system reliability.

Beyond coding, I focus on architecture governance, reliability, compliance and incident management. I define SLO/SLI practices, act as Incident Commander during critical outages, mentor engineers and standardize engineering practices.

Services I can provide

Focused, practical help for teams that need architecture, AI-enabled automation and reliable delivery — from discovery to production rollout.

AI workflow automation

Design and implementation of practical AI-assisted workflows: task routing, context preparation, draft generation, review gates and integration with existing tools.

Agentic development systems

Multi-agent operating models for software teams: source-of-truth knowledge base, runtime handoff, Git-based validation, reproducible commands and safe staging-to-production boundaries.

AI-ready knowledge bases

Structuring documentation, decision logs and project state so AI tools can use reliable context instead of scattered chats and tribal knowledge.

Search and recommendation systems

Backend architecture for content tagging, semantic/image similarity search, OpenSearch relevance evaluation and recommendation workflows.

Architecture audit and technical leadership

Assessment of platform boundaries, reliability risks, data flows, API contracts, release process, observability and team delivery model.

Data pipelines and automation

Production-grade data workflows, Airflow orchestration, migration planning, monitoring, retry policies and operational handover.

Enabled scalable onboarding and isolated deployments.

28B-record data migration

Role: Technical Lead / Data architecture · Context: X-FLOW

BigQueryPostgreSQLPartitioningIndexingApache Airflow
Problem
Move and restructure very large datasets into a scalable query model.
What I built
Built migration and restructuring pipelines with partitioning and indexing, orchestrated via Airflow.
Result
Reliable replication and scalable queries for ~28B records / ~2TB.

Airflow orchestration platform

Role: Technical Lead / Platform engineer · Context: X-FLOW

Apache AirflowDAGsRetry policiesSLAMonitoring
Problem
Standardize and improve reliability of production data workflows.
What I built
Deployed Airflow as a company-wide orchestration tool and built production DAGs.
Result
Cross-system pipelines with retry, SLA and monitoring.

ML-driven content search and recommendations

Role: Technical Lead / Backend + AI systems · Context: X-FLOW

GoPythonOpenSearchAI taggingImage similarity searchAutomated image descriptionsRecommendation systemsSearch relevance evaluation
Problem
Improve content discovery, search relevance and recommendation quality.
What I built
Built a content tagging system, image recommendation/search services and OpenSearch relevance evaluation framework.
Result
Foundation for ML-driven features and significantly better search quality.

OpenAPI CRUD framework

Role: Technical Lead / Developer experience · Context: X-FLOW

JavaScriptSwaggerOpenAPICode generation
Problem
Standardize API design and reduce repetitive implementation work.
What I built
Formalized code style conventions and built automatic CRUD generation around OpenAPI.
Result
More consistent API design and improved developer experience.

Multi-agent architecture for autonomous development

Role: System architect / AI workflow designer · Context: OpenClaw-based agent workflow

AI agentsAgent orchestrationLLM-assisted developmentPrompt/context engineeringObsidian knowledge baseGit-based handoffRuntime eventsHuman-in-the-loop review
Problem
Coordinate autonomous agents so they can work on real projects without losing context, duplicating decisions or bypassing review/deployment boundaries.
What I built
Designed a multi-agent operating model where Obsidian acts as the source of truth, project state is captured in tasks and decision logs, agents can continue runtime events, and code/deployment changes are validated through reproducible commands and Git history.
Result
A repeatable autonomous development workflow with persistent context, clearer handoffs and safer staging-to-production boundaries.

Released Google Play games

Architecture notes

Short, structured notes on how I think about systems, autonomy and engineering delivery.

Architecture as an operating model

Good architecture is not only diagrams. It is a set of boundaries, ownership rules, quality gates and feedback loops that let teams ship changes safely.

AI-assisted delivery

AI agents are most useful when they work inside explicit context: source-of-truth documentation, task states, decision logs, review gates and reproducible commands.

Reliability by design

I prefer systems where observability, SLO/SLI thinking, incident response and postmortems are part of the design rather than emergency additions after launch.
