Work journal.
Daily log of what I built, broke, and learned, generated from commits, agent pair-programming sessions, and field notes.
━ June 2026
WiredTiger in containers and controllership discovery
A day of turning an incident into technical content, publishing the previous daily entry, and deepening product discovery around margin and automation.
iTOP serverless architecture, a Postgres migration plan, and a post about RPC
An architecture day: a crashing VPS led to comparing Vercel, Neon and AWS, planning the iTOP migration to Postgres with tRPC, plus SEO/GEO on content and a post on RPC, REST and GraphQL.
Public pages, pricing calculator, and an interactive help center
A heavy day on the event platform: legal pages, a pricing calculator, a help center, a blog, and AWS architecture notes.
Portfolio audit, CV repositioning, blog date hygiene, and a working daily cron
Audited my GitHub repos for the portfolio, repositioned the CV as an agentic engineer, date-prefixed every blog post, and finally got the daily journal cron to fire at 23:00.
Portfolio docs for a SaaS, learning Rust through ai-memory, and bilingual posts
Wrote full English docs for the 3D print SaaS, dug into why ai-memory uses Rust, drafted architecture diagrams for itop, and shipped a batch of bilingual blog posts.
Building a 3D print shop SaaS across 20 parallel agent workspaces
A heavy day driving one SaaS to a working v1 through many parallel agent workspaces: inventory, orders, queue, dashboard, plus animated docs and an AWS migration study.
Shaping a 3D-print shop product and building a job-application pipeline
Turned a simple stock-control idea into a full product for a 3D modeling and printing shop, and built an end-to-end pipeline to draft and submit job applications.
A full day on job-search infra: ATS playbook, STAR writing, and interview prep
Built an ATS-friendly resume playbook, a STAR writing guide anchored to past experience, screened several roles for fit, and prepped study material for an upcoming interview.
Job applications at scale, a new AI repo, and an AI Engineer roadmap
A busy day spread across many parallel workspaces: a batch of job applications, bootstrapping an AI knowledge repo, an AI Engineer roadmap, two blog posts, and a Pi agent toolkit.
A heavy parallel day: career engine, blog drafts, and an architecture study
Ran dozens of parallel workspaces. Built a job-search skill, sketched a networking skill, studied durable execution, and queued several bilingual blog drafts with covers.
━ May 2026
Polishing application English and lining up portfolio proof-of-work
A short, focused day on the career repo: tightening the English in job-application answers and picking the portfolio links that best prove hands-on experience.
A day on career prep materials and tightening the blog CSS
Built reusable interview and pitch materials across several parallel workspaces, then cleaned up how the blog post styles are scoped so deleting a post no longer leaves orphan CSS.
A day on MCP: learning the concept, then turning it into a blog post
Studied what MCP is and where it fits versus a plain CLI, then drafted a bilingual post explaining the MCP client-to-server flow with diagrams. Plus interview prep.
itop data modeling review, a hotfix write-up, and some theory reading
Reviewed a staging-to-main PR on itop, dug into MongoDB best practices versus Postgres for the project, documented a hotfix, and read up on Paxos and ACID.
Parallel career-repo workspaces and sketching an AI-first company
Ran several career-repo workspaces in parallel to prep PRs and resolve merge conflicts, then started sketching how an AI-first team could run a real product end to end.
Trying interactive blog posts: MDX components and React inside the feed
Spent the day pushing one RAG post from plain markdown toward an interactive, animated layout, fighting performance issues with tabs and animations inside the post body.
Polishing the Markdown lingua-franca post: backing claims with papers and a new cover
Spent the day across several workspaces refining one bilingual post on why Markdown is the lingua franca for LLMs, grounding it in papers, softening the tone, and shipping a new cover.
Fixing the projects page locale bug and career branch upkeep
Tracked down a projects page that ignored the selected language and opened a PR, then did branch hygiene on the career repo with a main merge and conflict resolution.
Mapping how an agentic company runs, plus AI ideas for the event platform
Studied how a learning agent infra can serve a whole company, explored AI to improve the event-registration product, and dug into self-hosted deployment trade-offs.
Career workspace cleanup, staging sync, and removing a stray agent install
A lighter day across several workspaces: tidied two career branches with PRs and a conflict merge, synced a staging environment with main, and cleaned an unused agent off the machine.
Smooth scroll with Lenis, a post about it, and standardizing on Bun
Added the Lenis library for smooth scrolling, wrote a build-in-public post about the before and after, and moved another workspace from npm to Bun.
Cover art for the AI Engineering drafts, plus toolchain and study-repo cleanup
Generated agentic-futurism covers for the AI Engineering posts, reviewed the bilingual journal pair, cleaned up the local Bun/Pi setup, and organized a private study repo.
Daily journal now reads Pi and Codex sessions, plus AI Engineering drafts
Expanded the daily journal to capture sessions across coding agents and drafted seven bilingual posts on the AI Engineering stack for staggered release.
iTop electronic term, daily journal secrets policy, and new AI roles
The iTop e-signature feature took shape, the daily journal privacy policy got stronger, and I mapped out the new AI roles in the market.
Permissions matrix, AI code review, and a daily journal pipeline
Tightened role-based permissions, wired an automated PR review workflow, and shipped a bilingual daily journal with a /daily route.
Bilingual foundation, SEO bundle, and a public demo tour
Shipped full PT-BR/EN i18n on the blog, a major SEO + performance bundle, and a public interactive demo for an older project.
