13+ years of reading, writing and reviewing production code. I modernise ageing products and build AI features that do real work, without stopping delivery for the teams that depend on them.

Legacy platform modernised, no rewrite
Still building
Not writing about software from the sidelines.
I'm still in the work, solving the same problems every product team deals with. That's mostly what I bring into every engagement.
- Architecture that survives the second year.
- Shipping MVPs into production systems.
- AI features that do real work, not demos.
- Leading engineers through messy product decisions.
- Modernising legacy stacks without stopping delivery.
- Making expensive mistakes once, then documenting them.
Currently exploring
- Low level systems programming
- Rust
- Computer vision
- Voice AI
Learning closer to the metal so the next generation of products I build can see, listen and respond in real time.

What I deliver.
Product engineering across web, mobile and AI, from greenfield builds to hardening systems already in production. Engagements shaped around delivery, not billable hours theatre.
Architecture and modernisation
Incremental migrations of ageing products, from AngularJS to modern Angular and from legacy Express and MeteorJS to NestJS and PostgreSQL, without freezing delivery or rewriting from scratch.
ModernisationNestJSMigrations
Product engineering
TypeScript full stack from UI to API. Angular and React frontends, NestJS backends and production deployments that scale with the business.

AI systems & integrations

Ways to work together
Engagements.
Start small with an audit, commit to a fixed scope build, or keep a senior engineer on retainer. Every engagement starts with a free 30 minute call.
Paid audit
Fixed fee · 1 to 2 weeks
A deep review of your codebase, architecture and delivery process. You get a written report and a modernisation roadmap your team can execute, with or without me.
Fixed scope build
Most engagements $15k to $40k
A defined modernisation, AI feature or new product surface, delivered alongside your roadmap rather than instead of it.
Monthly retainer
Ongoing · monthly
Senior engineering and architecture on tap. Reviews, hard problems and hands on delivery for teams that need a principal level engineer without a full time hire.

Feedback from founders, leads, and teammates I've shipped with.
Erin Dunn Halligan
Founder at DesignCandy
“Rohit is great to work with. He is very responsive and very attentive to project detail and requirements. He and his team bring a robust spanse of programming and experience to the table, making app design and development a breeze when it comes to launching a high-quality product. With his help, we were able to produce a top-quality app called, 'Kwell,' now live on the App Store: https://apps.apple.com/us/app/kwell/id6547859478I would recommend him on any project.”

Pradeep Kumar
Tech Lead at Cognizant
“It was great pleasure to work with Rohit during his Cognizant days. I would highly rate him as a developer. He is a go getter and a constant learner. His passion towards technology and the drive to provide results along with his skills as team member would be a great asset to any organization.”
Vignesh Ravi
Team Lead at Pixel Magnus
“I worked with Rohit for around 2 years. Over this time period, we worked on a lot of things from Native app development, Backend development, hybrid applications, and Web development and he was good in all of these. He is a polite, dedicated, strong developer who can tackle any challenge that is thrown at him. If I were to work on something which needs a developer, Rohit would be one of my very few choices”
Zbigniew Nowak
Senior Frontend Engineer at ITSG Global
“I strongly recommend Rohit Kumar S. He is a solid programmer and a good team player.”

Common questions about working together
Open source & shipping
Active contributor.
Consistent commits on GitHub, and a lot more shipping that never shows up in a public chart. Client repos, private systems and production work behind the firewall.
