Originally posted 2026-06-24 Tagged: llms Since Opus 4.5 came out last November, my daily driving experience with coding agents feels like it’s stagnated. It’s not that AI has plateaued; it continues to accomplish feats that were not even in my realm of possibilities a year ago: codebases rewrites pinned to extensive unit tests , mathematical theorem proving , security exploit discovery ,…
Originally posted 2026-05-12 Tagged: llms , popular ⭐️ Does it make sense to hire junior engineers in the age of coding agents? Junior engineers are expensive, both in salary and seniors engineers’ time. This cost was partially recouped through code contributions, but today, it’s more effective to directly maximize the output of your senior engineers. The hiring market reflects this trend: senior…
Originally posted 2026-03-23 Tagged: llms , strategy , software engineering , popular ⭐️ Does it ever make sense to rewrite your codebase from scratch? For decades, the answer had been an unambiguous no, ever since Joel Spolsky argued that rewrites were the “single worst strategic mistake that any software company can make” . In the era of coding agents, the cost of writing code has dramatically…
Originally posted 2026-03-06 Tagged: llms This hot take on Moltbook which I started writing a month ago, is pretty lukewarm now - work ramp-up has kept me pretty busy. Nevertheless, I’ve adapted it into a more general commentary on agents, and I think it’s still quite relevant as the world continues to lean into agents. When we call a human agentic , we imply that they are active shapers of their…
Originally posted 2026-01-07 Tagged: personal , llms Reflecting on this past year, I feel grateful and lucky for everything that’s happened to me, both personally and professionally. I’m writing this from a remote town in Switzerland, where I train-hopped my way from Rome over the course of 3 days. My return journey is being pushed indeterminately due to cascading flight cancellations from…
Originally posted 2025-12-23 Tagged: personal About two months ago, I wound down my startup and started a job search. After ~15 companies and ~100 conversations with recruiters and interviewers, I am pretty happy to have found a great team at Jane Street working on agents. I’ll be in the NYC area and quite busy with onboarding/relocation for the first few months of 2026, but please reach out! This…
Originally posted 2025-12-22 Tagged: software engineering , strategy , machine learning , popular ⭐️ In my recent job search for an ML/AI engineering position , I talked to ~15 companies, made it to onsites for ~10 companies and received 7 offers. I did ~70 separate interviews, not counting recruiter/team match calls. My favorite interview by far was the one with Espresso AI’s CTO, where we…
Originally posted 2025-11-03 Tagged: personal , cartesian tutor , strategy 6 months ago, I started building Cartesian Tutor to explore AI tutors as the future of education. It’s been an incredibly rewarding journey and despite the lack of commercial success, I’ve learned a tremendous amount. A++ experience, highly recommended. I’ll be job searching over the next few months. If you are looking for…
Originally posted 2025-10-12 Tagged: llms , software engineering , popular ⭐️ For the last 6 months, I’ve been building an AI-powered tutor for teaching advanced chemistry. The codebase is roughly 98% AI-generated, but 98% is a highly misleading number. Yes, it’s true that if you look at the authorship by lines of code, Claude wrote 98%. But there has been so much human intervention that it would…
Originally posted 2025-09-24 Tagged: cartesian tutor , llms Progress update This week, I worked on building a “Review problem with AI” function that would import any question on my website into an AI for an AI-guided interactive solve experience. I originally thought that this would be just a convenience feature, so that students wouldn’t have to go figure out how to copy-paste the problem (and…
