What is your strongest stack?

React, Next.js, TypeScript, Node.js, Express, PostgreSQL, and MongoDB. I have shipped production apps across the full MERN stack for 8 years.

Do you work with US clients?

Yes. I have worked remotely with US clients through eCommerce Pack, VerifiedCRM, and reddev. Time zone overlap is not a problem.

Can you lead a project end to end?

Yes. I have served as project manager and full stack developer on ReplyWay and ReplySystem, and I co-founded reddev where I handle scoping, architecture, and delivery.

Do you build AI agents and automations?

Yes. I build production AI agents (WhatsApp receptionists, support bots, lead qualifiers) and event-driven automations, not just use AI in my editor. EatsDesk ships an AI Receptionist; I've built custom lead gen systems at scale for US service businesses.

Do you use AI in your workflow?

Yes. Claude Code and Cursor accelerate boilerplate and exploration, but I review, test, and own every line that ships. AI is a multiplier in how I work and in what I deliver for clients.

What makes your portfolio different?

Most projects are live in production with real users. I focus on multi tenant SaaS, high volume systems, and measurable impact rather than tutorial apps.

About

Ships fast. Ships clean.

Software engineer with 8 years in tech, from UI design and React freelancing to leading full stack delivery for US and UK clients. I started on Fiverr and Net Tech Ltd, moved into funded startups, and now run reddev while shipping products used by tens of thousands of people.

I co-founded reddev to build custom web, mobile, and SaaS products for international clients. My work spans multi tenant platforms like ReplyWay and ReplySystem, high volume CRM systems, HealthTech at Sunfish, programmatic SEO at scale across 500+ sites, and custom AI lead generation systems.

I specialize in the MERN stack, scalable architecture, multi tenant SaaS, and production AI, agents that take orders, automations that run on triggers, and lead gen pipelines that turn traffic into booked calls. I use AI tools (Claude Code, Cursor) as a force multiplier, but every line ships reviewed and tested. Most of my work is live in production. Click through and see it running.

Problem

Restaurants juggle orders across paper slips, phone calls, and disconnected tools. Most POS systems are expensive, hardware locked, and not built for fast food workflows in emerging markets.

Approach

Built a cloud-native, multi-tenant SaaS from scratch: POS, kitchen display, order management, admin panels, and AI Receptionist for WhatsApp ordering. Designed tenant isolation so each restaurant gets its own config, menu, staff roles, and AI agent without separate deployments.

Results

Shipped from zero to first paying customers
Full stack ownership: API, UI, deployment, and AI agent layer

Problem

A $10M funded HealthTech startup needed core patient facing features for a platform serving 50K+ users, with press coverage in Bloomberg, TechCrunch, and WSJ. Speed and reliability were non negotiable.

Approach

Built production frontend features on Next.js with strict code review standards. Worked within an existing architecture serving tens of thousands of users, focusing on performance, accessibility, and clean component patterns.

Process

How I ship.

Understand the problem

Map business goals, user flows, and constraints. Define what success looks like before writing code.

Architect for scale

Choose the right stack, data model, and tenant strategy. Plan for production from day one, not as an afterthought.

Build and iterate

Ship in small, testable increments. Frontend, API, and infrastructure in parallel with tight feedback loops.

Deploy and measure

CI/CD, monitoring, and performance checks. Track real metrics: load times, conversions, and user adoption.

Principles

How I think about engineering.

Production over prototypes

If it is not deployed and used by real people, it does not count.

Depth over breadth

Three excellent, documented projects beat fifteen half finished ones.

Own the full stack

API design, database schema, UI, and deployment. No hand waving across layers.

Measure what matters

Users, performance, and business outcomes. Not lines of code.
