Services

Engagements are scoped around a platform: architecture and build, the AI layer, the infrastructure underneath, and the operating discipline that keeps it live.

AI Engineering

AI built into the platform, not bolted on: MCP servers that give assistants safe, permissioned access to a product's data and actions, agent pipelines that draft, review and publish behind human approval gates, and integrations with the model providers the use case actually needs. An AI client is treated like any other client of the backend, authenticated, scoped and audited. The proof point is a live MCP server running in production against a real platform.

App Development

The platform's apps, wherever the users work: React Native and Expo for iOS and Android, shipped through both stores, and Electron with React for the work that lives on the desktop, offline-ready and packaged for Windows, macOS and Linux. The app is never a separate product, it is a surface of the platform, wired to the same backend, auth and data model as every other client and released on the same cadence.

Website Development

Web frontends built on React, Next.js and Tailwind against a headless CMS: server-rendered, localized, structured for search engines and AI crawlers alike. The same discipline whether it is a marketing site or the web face of a multi-tenant platform: performance measured, content modelled, deploys automated.

DevOps Engineering

The infrastructure underneath the platforms: Kubernetes clusters on owned or cloud hardware, Dockerized services, CI/CD that ships on push, automated TLS, monitoring, scheduled backups and zero-downtime cutovers. The proof point is a production migration off managed cloud with no minute of downtime recorded.

Startup Development

A platform taken from architecture to first customers: the data model, the backend, the surfaces, the deploy pipeline and the operating discipline, scoped so the MVP is a thin slice of the real system rather than a throwaway. Built to survive the growth it is hoping for.

Additional Services

The work around the platform: UI/UX design, headless CMS builds on Strapi, integrations with third-party APIs, architecture reviews and pre-build technical scoping. Smaller pieces, held to the same standard, because they are what keeps a platform coherent.

Highlights

A few platforms told properly: what they are, how they are built, and what they run on. Each one links to its full case study.

Fully Booked - All-in-One Smart Booking Solution

Fully Booked is a booking platform for UK minibus and coach hire and the job-sharing network of operators behind it. A customer describes a trip once on the customer website and receives offers from the operators who can serve it, ranked with reviews and vehicle photos, then books with a small protected deposit. An operator who cannot take a job refers the customer from the app, and earns a share when another firm in the network carries it. Around that loop sit quotations, cancellations, Get Covered, partner contacts, stored bookings, a wallet, business pages and the Prebooked widget, all on one backend and run from an admin control room.

Fully Booked - Customer Booking Website for Group Trips

The customer side of Fully Booked. A customer who comes to the site directly, or through an operator's referral, fills in one form, receives offers from operators in the area with reviews and vehicle photos, chats without exposing contact details, and books with a small deposit that is held until the trip goes ahead. Every operator also has a business page where customers can book them directly and come back for the next trip.

AI Engineering - MCP Servers and a Cross-Provider Memory Hub

Assistants forget between sessions, and each provider keeps its history in its own shape, so knowledge earned in one conversation is unavailable in the next. We built the plumbing that fixes it: MCP servers that expose knowledge, content and tools to any assistant, and a memory hub that normalises sessions from several providers into one queryable store. None of the hard problems here were prompt problems. They were system problems: schema design across incompatible session formats, isolation between scopes, tool safety, and an approval model for anything that writes. It runs on self-hosted hardware, so nothing leaves the building.

Where I have Been Employed and What I Have Done

Webanion • Full-time

2 positions

Feb 2021 - Present • 5 years 8 months

Dhaka, Bangladesh • On-site

Founder & Software Architect

Sep 2026 - Present • 1 month

Webanion is my full-time practice. I design and build AI-native platforms and the infrastructure that runs them, agent systems and the guardrails around them, MCP servers, multi-provider model routing, and durable orchestration for work that has to survive failure rather than restart from the beginning. The delivery stack is TypeScript end to end: NestJS and Node on the backend, Next.js, React and Vue on the front, React Native and Electron where a product needs to leave the browser, and self-hosted Kubernetes that I run and operate myself. I take on platform and AI engagements where the hard part is making the system reliable, not making it demo well.

Founder & Full-Stack Engineer

Feb 2021 - Aug 2026 • 5 years 7 months

At Webanion, I’ve worked as a versatile full-stack developer contributing to a wide range of internal tools, client applications, and cross-platform products. My responsibilities included mobile apps with React Native, frontend with React + Tailwind, backend with NestJS, and deployment using Docker.

CTO and Head of Engineering

Jun 2026 - Present • 4 months

Technical owner of architecture, infrastructure and technology direction for a platform around a thousand people use every day. Moved the entire live system off managed cloud hosting onto self-hosted Kubernetes with no recorded downtime: a hardened k3s cluster behind Traefik and a Cloudflare tunnel, per-service Kustomize manifests, gated production deploys and out-of-band secret management. A recurring cloud bill became infrastructure the business owns from DNS to disk. Three years on, the same architecture is still shipping without a rewrite, which is the real test of the early decisions.

Lead Engineer

Jan 2025 - May 2026 • 1 year 5 months

Turned a delivered product into one that ships predictably. Consolidated seven codebases into a monorepo with a phase-based release workflow and CI/CD on GitHub Actions: path-filtered builds, automated per-surface versioning and tagging, and gated production deploys. Shipped Prebooked, an embeddable booking widget published to npm that turns any partner site, hand-built, WordPress or Wix, into a booking channel with one line of script. Alongside it a public documentation site, Google Maps trip integration, per-domain CORS management, and continuous store submissions on both platforms across four versioned platform releases.

Full Stack Engineer

Apr 2023 - Dec 2024 • 1 year 9 months

Built the platform from the first commit to production, solo. A React Native app on Expo live on both stores, a customer enquiry site, operator and admin dashboards in React, and a NestJS and GraphQL backend on MongoDB serving all of them, so a booking made anywhere was visible everywhere at once. Square payments, Twilio messaging, live notifications and an offline mode. Containerised with Docker and deployed on DigitalOcean. The UI design was the only part I did not do myself.

Senior Full Stack Engineer

Apr 2023 - Present • 3 years 6 months

Fewer, larger and longer engagements, with end-to-end product ownership rather than task work. A UK booking platform taken from MVP to production across forty milestones and still running. An eighteen-month product engagement delivered milestone by milestone, eleven accepted. One client relationship across five contracts and nearly three years. Paid architecture consultations for founders deciding how to build. The work spans mobile, web, desktop and infrastructure: React Native and Expo, Next.js and React, Electron, NestJS and Node, PostgreSQL and MongoDB, Docker and Kubernetes, and increasingly the AI and agent layer on top of it. Top Rated with a 100% Job Success Score across 45 contracts, featured among Upwork's top React Native and React developers, with top 3% global performer recognition in 2024.

Full Stack Engineer

Dec 2021 - Mar 2023 • 1 year 4 months

Twenty-six contracts across React, React Native, Node.js and WordPress for clients in the US, the UK, Europe and the Middle East: features, fixes, deployments, UI builds and store submissions. Two things came out of it that outlasted any single contract. A 100% Job Success Score held from the start and never broken, and repeat business as a pattern rather than an accident, with several clients coming back three and four times.

Engineering Lead

WorkflowFiesta • Contract

Feb 2026 - Jun 2026 • 5 months

United States • Remote

As engineering lead at WorkflowFiesta, I owned an AI workflow automation product line end to end and directed a distributed engineering team. My work covered agent-driven workflow design, large language model integration spanning multiple providers, and durable orchestration so that long-running jobs resume instead of losing state on failure. Day to day this meant shaping architecture decisions, reviewing and unblocking the team's work, designing safe database migrations, and tracing problems from the interface down through services to the data model. I worked on a multi-tenant platform with per-tenant isolation, and partnered closely with product and QA to turn complex automation requirements into reliable, maintainable systems.

Full Stack Engineer

Testfiesta • Contract

Dec 2025 - Jun 2026 • 7 months

United States • Remote

At TestFiesta, I work as a full-stack engineer focused on platform reliability, performance optimization, and resolving complex issues across a highly asynchronous, distributed system. I debug problems across the full stack, frontend rendering, Node.js backend logic, PostgreSQL queries, worker execution flows, and service-to-service communication. My responsibilities include designing safe database migrations, improving query performance through indexing and refactoring, and tracing UX issues from UI interactions down to backend and data models. I collaborate closely with QA and UI/UX teams to reproduce edge cases, analyze GitHub issues, and deliver high-quality fixes. Within my first month, I resolved over 50 complex issues, significantly strengthening system stability, scalability, and overall product performance.
