AWS & Serverless
Designing systems on AWS using Lambda, API Gateway, SQS, DynamoDB, S3, and friends. Event-driven architectures that scale to zero when idle and absorb traffic when it counts.

About
A decade of
shipping software.
Ten years of writing software for a living — backends mostly, but with frequent detours into infrastructure, tooling, and the quiet corners where systems fail.
I try to write code that the next person — including future me — can read, reason about, and trust. Clarity over cleverness; honest seams over hidden magic.
Outside of product work, I spend time on information security: reading research, tearing apart how things work, and thinking about the threat models that real users actually face.

Stack
Tools I reach for.
- 01
Golang
High-throughput services, API development, and the kind of plumbing that must run quietly for years. Strong typing, simple deployment, honest performance.
- 02
Ruby
Rails apps, internal tools, and quick iterations on product ideas. Expressive code, a mature ecosystem, and a community that takes craft seriously.
- 03
PHP
Modern PHP — Laravel, typed code, decent tooling. Still powers a huge slice of the web, and still a pragmatic choice for many real problems.

Platform
Cloud, media
& intelligence.
Beyond writing code, I work across the platform layer — building on AWS with serverless services, shipping video and audio streaming pipelines, tuning CDNs from the edge to the origin, and integrating AI into products in a way that earns its keep.

Video & Audio Streaming
Building delivery pipelines for live and on-demand media — transcoding, adaptive bitrate (HLS / DASH), packaging, and playback that survives the messy realities of real networks.
04.303 / 04
CDN Integration
Integrating CloudFront and other edge networks — cache strategy, signed URLs, origin shielding, and the small configuration details that quietly decide cost and latency.
04.404 / 04
AI Integration
Bringing LLMs and generative AI into real products — prompt design, tool-using agents, and the practical integration work that turns model APIs into features users can rely on.

Focus
Security isn’t a checklist I bolt on at the end — it’s a way of reading code.
I read up on web application security, supply-chain risks, authentication design, and the steady stream of vulnerabilities that shape how modern software gets attacked.

Web application security & OWASP-style review
- ii.
Authentication & session design
- iii.
Supply-chain & dependency hygiene
