About Me

Most engineering problems are not just about code. They sit somewhere between the system and the people building it. That is where I have spent most of my career.

I am a software architect who works hands-on while leading teams and shaping how organisations build and operate systems.

Over the past 11+ years, I have worked across early-stage startups and large-scale platforms. I focus on taking unclear ideas, turning them into working systems, and making sure teams can actually use and evolve them without friction.

At a HealthTech startup, I joined as one of the early engineers and helped build the platform from scratch. As the company grew to 300+ engineers, I led platform and infrastructure efforts that supported over 800 services. This included CI/CD, internal tooling, cost controls, and reliability practices that made day-to-day development faster and safer.

At HelloFresh, I led the GraphQL initiative from the ground up. That meant learning the space quickly, defining the architecture, aligning with leadership, and driving adoption across teams. In parallel, I worked on  Server-Driven UI, helping product teams ship changes without waiting for app releases. Both initiatives moved from early discussions to production systems used across the organisation.

Earlier at ThoughtWorks, I worked with Ministries of Health in East Africa to roll out clinical systems such as Bahmni and OpenMRS. This involved building local teams, working closely with hospitals, and delivering software in environments where downtime had real-world consequences.

Today, I lead compliance and risk engineering  for a large-scale iGaming platform. The systems I work on serve over 30 million users across multiple markets and handle peak traffic of around 12k requests per second.

I still write code, review designs, and stay close to the systems I build.

Because in the end, architecture is not just about designing systems. It is about making them work in the real world.

My expert
areas

I have extended experience around software development and leadership in both MNC and Start Up. Different organizations teach different skills. Starting from working with Govt. of different continents to promoting agile to a global level. From setting up office of a startup to leading Infrastructure alliance for parent organization and all subsidiaries.

When it is about the product development, it's all about the right technology and teams with providing scalable and sustainable product. Following the analogy, Achieve 80% of work with 20% of effort.

Selected work

Things I've shipped.

A few of the systems, platforms, and products built along the way. The full list has more.

Progresify hero2026
Next.js · Go · PostgreSQL

Progresify

A goal-driven people platform I designed and built solo, connecting OKRs, structured 1:1s, and performance reviews to real engineering output so reviews are grounded in evidence rather than memory.

Prismo hero2025
Next.js · Go · PostgreSQL

Prismo

A freelance management platform built solo: client and project management, time tracking, and invoicing in one system. Built for technical freelancers who spend more time on admin than they should.

Tools
That I Use

In my experience working in MNC and Start Ups, I came across multiple tools, frameworks and languages. All of them helped me someway or other to grow and help the business to scale. I have curated few of them which I use on daily basis.

Please note this is not an exhaustive list. I am always open to learn new things and adapt to new technologies. Also these are not sponsored tools. I have used them and I am happy to recommend them.

Fancy a chat?

There is nothing called a simple / stupid idea.

Fractional engineering leadership, platform work, delivery rescue, or a second pair of eyes on the architecture. Drop me a line if you reckon I can help.
