The start. Four years of computer science, then the first lines of production code and the discipline of shipping.

Databases, deployments, and learning the hard way what it takes to ship — Java, PHP, C++. The foundation everything else is built on.

Stepped out on my own — taking on projects directly for clients around the world, learning to sell, scope, and ship without a team behind me. The bridge between being an engineer and becoming a founder.

My first software services company. Years of white-label delivery for agencies — web, mobile, custom systems. This is where my delivery instincts were built.

Early experiments in products and e-commerce. Both closed. Both taught me more than the things that worked.

Ran a US booking platform for over five years as VP Engineering — keeping one production system alive and scaling while the business grew.

Urgently brought in during COVID to help disburse aid funds. Worked in person and from home, guiding their team and architecting CAMS — the Central Aid Management System — that got those funds to the people who needed them. And quietly started automating my own business operations — the habit that grew into everything I do today.
A delivery and execution partner for agencies and product teams, working behind the scenes on fixed-scope projects so founders can sell outcomes without delivery chaos. The company I run today.

My own product — a fitness and trainer marketplace. Owning the product end to end, not just delivering for clients.

A product company for website owners — WordPress plugins, Shopify apps, SaaS tools. PDF Search Pro is the first major release.

Doing real business work — recruiting, content, operations. The through-line from that 2020 automation habit.

A lightweight CRM your team can operate directly — or safely through AI.
An AI sales agent that answers questions, qualifies visitors and turns conversations into customers.
An all-in-one platform for gyms and trainers — clients, workouts, bookings, payments and growth.
A product company for website owners. Plugins and apps that solve one problem well.
04 / Client work
Systems I led or built — with my teams at CodersBucket and Instalogic, or from inside the client as their engineering lead. Deliberately separate from products I own.
National-scale platform
A high-traffic public system where reliability and load handling mattered more than anything else. Delivered with my team.
Booking platform · US
A US wedding booking platform — bookings, vendors, scheduling and payments. I ran engineering there as VP Engineering from 2019 to 2024.
I build AI agents and n8n workflows that take repetitive work off a team. Pick an example to see how one works, step by step.
Without it
Someone on the team reads every application by hand, and good candidates wait days for a reply.
A person stays in control
The hiring team makes every decision. The AI only sorts and explains.
Runs inside
New application
A CV arrives from a job form or an inbox.
Read the CV
The CV is parsed into skills, experience and history.
Score against the role
An AI agent compares it with the job's requirements and explains its score.
Shortlist
A ranked shortlist, with the reasons, goes to the hiring team.
Built with n8n, LLM agents and retrieval over your own documents, connected to the tools you already use.
