Role Summary: We’re looking for an application developer who thrives at the intersection of software engineering and client delivery. You’ll design, build, and deploy production-grade applications—often integrating AI or data-driven components—and work closely with enterprise clients on-site (~50% travel). You’ll collaborate with our AI and data science teams to bring robust, user-ready systems to life.

Requirements: 1. 4–7 years of experience in full-stack or application development. 2. Strong proficiency in Python, JavaScript/TypeScript, and modern frameworks (e.g., React, FastAPI, Node.js, or Flask). 3. Experience deploying to cloud environments (AWS, GCP, or Azure). 4. Ability to translate business requirements into maintainable, scalable code. 5. Excellent client-facing communication and collaboration skills. 6. Willingness to travel up to 50% for on-site work with U.S. clients.

Ideal Profile: A hands-on builder with a consulting mindset—comfortable both coding independently and representing the team in client environments. Prior experience in AI product development, data-intensive systems, or enterprise integrations is a plus.

Requirements: 1. 1–3 years experience in machine learning, Python, and data pipelines. 2. Exposure to cloud environments (AWS, GCP, or Azure). 3. Comfortable working independently and asynchronously with remote teams. 4. Good communication skills and disciplined execution. 5. Bachelor’s in Computer Science, Data Science, or related field.

Ideal Profile: Early-career data scientist or ML engineer with a startup or research background; eager to learn, ship fast, and grow into a lead role.

Requirements: 1. 6–10 years in applied machine learning, data science, or AI product development. 2. Proven experience with enterprise clients or consulting environments. 3. Strong communication and presentation skills. 4. Technical depth in model design, MLOps, and data strategy. 5. Master’s or PhD preferred but not required.

Ideal Profile: Ex-FAANG, Ex-MBB, or similar background; confident, articulate, credible in front of senior stakeholders.

Start by splitting Google into two identical, full-stack companies, each with all the core products. A year later, split them again. Over time, you get 4 or 8 Googles competing across the board.

Employees could be assigned algorithmically to avoid chaos. This feels more like cell division than amputation—preserving the synergies while creating competition.

Position: Swift Developer

You will: 1. Build in Swift. 2. Creating fluid swipe and transition animations. 3. Optimizing data structures to minimize server load times by predictive preloading and caching. 4. Integrate OpenAI APIs into a Swift front-end (I already deployed a prototype that works). 5. Implement fast and reliable peer-to-peer, one-on-one video streaming. 6. Implement Web3 payment integrations on CELO Level 2 blockchain, including Apple Pay token purchasing.

I will: - Pay you $1,000/month while we aren't funded. - Meet w you 30 minutes/day to review, problem solve, and plan your 7-8 hours of work. 4PM Singapore time. - Use V0 by Vercel prototype as design reference.

Attributes: - Work hard.

1. Estimate the hours you think it will take to complete a task.

2. Double it and let the team know you did that.

3. Do the work well including good documentation.

4. Assess your progress when you've spent 50% of the planned hours. If you're not at least halfway done, avoid overworking. Instead, seek help within the team and descope.

5. Utilise any extra time for learning new and useful skills, if you finish ahead of schedule.

When I find myself repeating the same topic, I write it down for future reference.

Writing is enjoyable, with the added anticipation that my children will read it someday (with mild embarrassment).

Let's be clear that for a 5 year old, being able to substitute numbers in (+ 2 3) and seeing the results is displayed on the screen is pretty cool. And for my 3-year-old, just typing his name (after I tell him which keys to press) is magical.

Are you not convinced that Google Search, DDG, Gmail, Facebook, WhatsApp, Snapchat are all "good" products in the eye of many people? As far as I can tell, all of those products are paid for by sponsors.

I may have biased it, but she found the experience more engaging than MIT Scratch (which is also very good).

When kids and newbies engage with a product so easily (think git before github), you suddenly vastly increase the userbase.

I, too, find it easier to apply consequentialism, but bureaucracies work well when they have clear rules.

Thank you, advertisers, for paying for Gmail and all those good products.

Bugzilla -> Redmine -> Jira -> Trello/Asana -> Gitlab -> ...

I'd say things are slowly getting better.
