I’m Ritesh, a Software engineer currently based in Singapore. I care about systems that are correct by construction and programs that outlast the enthusiasm of the people that wrote them.

This space is a recent effort at maintaining a digital garden. It’s fresh and will be consistently grown.

Current Focus #

I’m looking for the right role — the next problem- / solution-space to direct my attention to for the long-term. Small, strong teams where the business thrives on impactful work put in by passionate people; a deeply technical IC role in a place that cares about the quality of its systems. I’m particularly interested in distributed systems, networks, and the kind of engineering where taste is not a dirty word.

In the meantime, I’ve been finishing the Songs of the OCaml Compiler series — a three-part write-up on building a Paxos consensus simulator in OCaml and what the type system forced me to reconsider — alongside some consulting work Most recently, was working on auditing the architecture of an R&D spin-off in the local robotics industry, giving clarity on how to model their data and control planes better as they scaled their operations as part of a Sino-Singapore effort. If you’re a non-profit that needs guidance or architectural audits, please reach out! I wish to keep this as at least a probono-side commitment alongside my main focus. on Software Architecture and other cultural projects These warrant a blog post of their own \(\ldots\) will put them up soon . This comes after transitioning out of a Technical Founder I co-founded Perkpal, a local marketing-tech startup where we were helping distributor-reliant brands have better visibility into their early adopters and form direct relationships with them via physical/digital perks embedded onto physical spaces or things. It was an extremely eventful experience, where we landed clients from around South-East Asia, many of whom were operating across multiple markets and also interfaced with some enterprise giants. I play an advisory role now since it’s primarily sales-led. role at the end of 2025.

Previous Focus #

  • Late 2025 — March 2026: Software Architecture advisory in robotics, physical AI space – data plane design, control plane architecture with an actor-model, sensor pipelines, digital twins.

  • Q3- 2024 — Late 2025: Technical Co-founder at Perkpal Built the core product 0-to-1: full-stack, infrastructure, integrations. Small team, high ownership. , a marketing-tech platform. Built the product from scratch, felt the sweetness of having positive cash-flow distilled from the typical chaos of a bootstrapped business.

  • May 2024 — June 2024: Walked away from an exciting new job from a NYC based company after a month when it became clear the product direction and engineering culture weren’t aligned with how I work.

  • Jan 2022 — April 2024 : Software engineer at OutPoint (acquired) Marketing attribution tooling for DTC brands. Joined early, contributed to the engineering that carried the company to acquisition. , a marketing attribution company that offerred a Media Mix Modelling product (MLOps platform for media-spend analysis). Explored Toronto, fell in love with the Canadian Rockies too.

  • July 2023: Completed my Bachelor’s Degree – Honours with Distinction. Specialisations in Security and Software Engineering. Also did an exchange at the University of Toronto for 2 semesters while working full-time at OutPoint.

  • ~2019: Wrote my first official hello world when I matriculated into the Computer Science degree programme at National University of Singapore. Did a whole lot of distro-ricing and TOR-rabbit-holing on the side as a freshman until my NAS got hacked That’s why I ended up taking a bunch of interesting Computer Security courses in the later part of my undergrad years. The coolest of them focused on Malware Analysis where we did malware disassembly – kudos to the ingenuity of hackers (regardless of the colour of their hat). and I learned to be better.

I am on Codeberg (recently active) and have some old repos @ Github. Field testing some self-hosted forgejo sessions, will update this eventually. I’m also occasionally active on LinkedIn. My handle, rtshkmr “riteshkumar” without the vowels , seems to be unique enough so it’s usually the handle for most platforms.
