Hello, I'm DAVID AGHAYAN
Senior Software Engineer
10+ years building full-stack, AI-powered systems with PHP/Laravel, Python, Vue.js, and Go. I architect resilient platforms that scale, and I build the tooling that multiplies my team's velocity.
About Me
Full-Stack. Product-Minded. AI-Native. Reliable.
Calm systems, calm teams.
Ten years of owning delivery from raw code to production. I've led performance upgrades, built data pipelines, and replaced manual toil with automation. My definition of reliability: nobody gets paged. I invest in monitoring, tests, and boring, predictable deployments. The best production fire is the one that never starts.
Product-minded & pragmatic.
I ask "why" before I build, so the team doesn't burn weeks on the wrong feature. Years of working directly with enterprise clients means I can sit in a stakeholder meeting and translate effectively in both directions. Pragmatic about scope, strict about the code and architecture that have to last.
AI-native, human-friendly.
I leverage AI agents and custom automation to eliminate toil, allowing engineering teams to ship faster without the burnout. The systems do the heavy lifting; people get the interesting problems.
How I work
- Thorough, constructive code reviews - I leave PRs better than I found them.
- Documentation by default - no bus-factor-of-one systems.
- Active mentorship - my win condition is the whole team leveling up.
- Low drama, high ownership.

Agentic AI & What I'm Building Now
The areas I'm working in and most interested in right now
Agentic AI Systems
Designing autonomous agents that plan, reason, and use tools to get real work done - with orchestration, guardrails, and evals so they're safe in production.
LLM Engineering
Production RAG, fine-tuning, and context/prompt engineering - structured outputs, hallucination controls, and ruthless cost & latency optimization.
Model Context Protocol & Tool-Use
Building MCP servers and agent-ready APIs so models can safely act on real systems - the connective tissue between LLMs and production infrastructure.
AI-Assisted SRE & AIOps
LLM-driven incident response, anomaly detection, and automated remediation - keeping systems at 99.99%+ while shrinking toil and MTTR.
Vector Search & Retrieval
Embeddings, semantic and hybrid search powering grounded AI features - retrieval that actually returns the right context at scale.
Production ML Platforms
Scalable inference, model observability, and reliability engineering for ML systems that stay fast and reliable in production.
