02How I work

Small scope, weekly demos, measured AI.

The same loop whether you hire me for a six-week build or as a senior engineer on your team.

  1. 01

    Scope

    A 20-minute call, then a one-page brief: the manual work we are removing, success metric, data sources, and what ships in the first two weeks.

  2. 02

    Build in the open

    Weekly demo on a staging URL. Typed APIs, tests on the paths that matter, evals for any LLM feature so quality has a number.

  3. 03

    Ship & hand over

    CI/CD, monitoring, docs and a Loom walkthrough. You own the repo and the infra. I stay on for support if you want it.

03Services

What I can take off your plate.

Scoped projects, retainers, or embedded in your team. Each service ships with CI/CD, monitoring and docs.

  1. 01

    AI & LLM Integration

    RAG document Q&A, customer-facing assistants, and LLM workflow automation built into your existing web apps, with OpenAI, Anthropic and vector databases.

  2. 02

    Custom Software & SaaS

    Multi-tenant SaaS, ERP, CRM, POS and dashboards: modular Laravel or Node backends with React or Vue frontends, built to scale.

  3. 03

    Device & Hardware Integration

    Biometric attendance and punch devices, POS hardware, barcode scanners and IoT sensors synced in real time with HR, payroll and production systems.

  4. 04

    DevOps & Cloud

    Docker, AWS, Azure, CI/CD pipelines and infrastructure as code, so you deploy daily instead of monthly.

  5. 05

    E-commerce & Payments

    Storefronts, PWAs, payment gateways, shipping APIs and order tracking, from catalog to checkout to delivery.

  6. 06

    Mobile App Development

    React Native iOS and Android apps sharing one API with your web platform.

04About and experience

Seven years from POS hardware to LLM pipelines.

LLM features in every build since

I started integrating barcode scanners and punch devices into PHP apps, then spent six years building SaaS, ERP, CRM and e-commerce platforms that teams depend on every day, for organisations like UNICEF, Robi Axiata, Novo Nordisk and Oxfam.

Since 2024 my focus is making those systems smarter: RAG document Q&A, customer-facing assistants and LLM-driven automation, with evals and cost tracking so the AI parts are as reliable as the rest.

I like small teams, clear briefs and shipping weekly. I write and record short engineering videos on the side.

08FAQ

Before you reach out.

Do you work US hours?

My day overlaps with US East mornings, and I keep EU hours fully. For urgent items I am reachable later. Async-first teams work best with me, but I have shipped with daily stand-ups on US time.

Full-time, contract or both?

Both. I am open to remote full-time roles as a senior or lead engineer, and to contract or fractional work for product teams and agencies.

Can you join an existing codebase and team?

Yes, most of my work has been inside existing Laravel, Node and Vue/React codebases. First week is reading, tests and small PRs, then larger features.

What does an AI feature project look like?

Usually a RAG assistant or a workflow automation on top of your existing data. Two to six weeks for a first production version, with evals and cost tracking from day one.

Fixed price or hourly?

Fixed price for scoped projects after the brief. Hourly or monthly retainer for ongoing work.
