The Story

I joined LeanSwift as the only mobile developer. They were an Infor M3 ERP services company that wanted to move into mobile, and they handed me a blank page: build the platform, build the team, build the products, build the distribution.

I built a prototype to convince senior management, got the budget, and grew it from there. For a few years I was product owner, scrum master, tech lead, and architect at the same time.

Core Engineering Work

01Designed the whole architecture — UI layer, backend integration with M3 microservices, local storage, offline sync, push notifications, and the functional flows on top. Every backend call was a typed message over one shared networking core — around seventy operations, from inventory counts to manufacturing orders — with multi-connector OAuth refresh handled invisibly.
02Worked with M3 consultants to understand ERP modules, and with backend engineers to create the microservices that fed the apps.
03Grew the team from one to more than ten — iOS engineers, a designer, QA — and mentored as we went.
04Set up CI/CD, App Store licensing and distribution, and the release cadence that shipped modules version after version.
05Shipped the suite localized in English, Japanese, and Swedish, with barcode capture through both the camera and paired Bluetooth hardware scanners for warehouse-speed entry.
06Built the field-warehouse trio — Inventory Counting, Goods Receiving, and a Merchant Metals Proof of Delivery app that loaded the delivery manifest, captured receiver signatures plus on-site photo and ship-ticket scans, and generated the M3 invoice on approval — collapsing deliver-to-bill from days of paperwork into one on-site flow, offline-tolerant through Core Data so dead zones on the route never blocked a driver.

Analytics & Retention

I flew to the USA repeatedly to sit with clients, understand their operations, and bring requirements home as concrete product plans. Two of those trips lined up with WWDC 2017 and 2018, where I met Apple engineers on M3 integration and the Objective-C to Swift migration.

App

MobileFirst for Infor M3

The flagship ERP client — one app that walks a warehouse line from the M3 connection all the way to a signed delivery: configure, pick, inspect, and prove receipt against a live backend.

MobileFirst signing in against a live Infor M3 environment

The module drawer — Pick Reporting, Goods Receiving, Proof of Delivery, Inventory Counting and the rest of the M3 suite behind one login

Customer Info — a customer's M3 account and site location pulled up in the field, with click-to-call

Pick Reporting — choosing the warehouse to work against before a floor task

PO Inspection — grading a received line on a 0–4 quality scale, routing approved and rejected quantities to bin locations

Goods Receiving — purchase-order lines walked to line-level received quantities

Proof of Delivery — capturing the receiver's signature on site to close the delivery and trigger M3 invoicing

Barcode capture — choosing the built-in camera or a paired Bluetooth hardware scanner for warehouse-speed entry

Search — filtering a stock take by facility, warehouse, and status before a count

Inventory Counting — a count's report lines (item, location, lot, quantity) ready to submit

PO Inspection — approved and rejected remarks with a reason code, then slide to confirm

App

Inventory Counting

Scan-first stock counts for warehouse floors — offline-tolerant, with batch line upload over patchy Wi-Fi.

App

Proof of Delivery

Built for US steel-fence distributor Merchant Metals: drivers work the delivery manifest line by line — reconciling delivered against ordered quantities with per-line notes — then capture site photos, scan the paper ship ticket page by page, and take the receiver's signature on screen. Approving the delivery generates the M3 invoice and emails confirmation, turning a paper POD slip into a same-minute billing event.

Goods Receiving

The third leg of the warehouse suite — purchase orders walked from list to line-level receipt confirmation, on the same shared M3 core.
