The computer integrated systems design practice, sheet by sheet

LSJ Consultation, LLC designs computer integrated systems for operators of every size across the United States. Our work lines up under six bound ledgers, each naming a distinct discipline. The paragraphs on this page give the full narrative behind the numbered sheets that appear on the homepage, so an operator can read what is in scope, what the office produces, and how each ledger closes.

Six bound ledgers of the practice

Enterprise Systems Integration

Begin intake

A typical operator in the United States carries a long shelf of purchased and custom applications, each keeping its own record of the same customer, order, invoice or asset. Enterprise systems integration is the discipline of making that shelf behave as one filing cabinet. We begin by drawing a current state map of every application, every data owner and every hand-over point. We name the overlaps, the copies of truth and the quiet hand-written steps that hold the old system together. Then we design the future architecture: which application stays the master of each record, which becomes a subscriber, and how the records stay in step. Along the way we plan the reconciliation and error handling that keep a clean single canon. What is delivered is an integration landscape that a new engineer can read in an afternoon and that the business can extend without trauma.

Custom Software Architecture

Begin intake

Where no purchased shelf fits the work, an operator needs software built to meet its own shape. Custom software architecture is where we earn our reputation. We take the intended behaviour and turn it into a structural drawing before a single line is written for production. Boundaries are named; the responsibilities of each component are written down; the interfaces between them are agreed in the same language a developer and a non-developer can each read. We decide how the code will be divided, how it will be tested, and how changes will be promoted from a developer desk to the live services. The result is not simply a program that runs. It is a program whose architecture is so clear that the next developer, and the next owner, can keep improving it for years without fear.

Cloud Infrastructure Design

Begin intake

Cloud estates grow quickly and quietly into a tangle of untagged environments, personal click-built boxes and accidental public openings. Cloud infrastructure design brings that estate onto the ledger. We structure it as named projects and environments, each with an owner, a purpose and a written lifecycle. Networking is laid out into guarded regions with the least privilege that still lets people do their work. Provisioning moves onto repeatable templates stored under version control, so the same configuration can be rebuilt for test, staging and production and there are no secret deviations between them. We also put cost and usage under visible reporting so the company can see what it pays for. What matters most is that infrastructure stops being magic and becomes an audited, reproducible part of the business record.

Legacy System Modernisation

Begin intake

Many valuable business rules live in systems of real age: a finance platform from a vanished vendor, a database nobody dares to touch, a desktop application wedded to an old server. The wrong instinct is to rewrite blindly. Legacy system modernisation is a patient act. First we read the old system and write down exactly what it does, which rules it enforces and which records it keeps. We run a transfer audit that lists each table and file and who relies on it. Then we decide between several honest paths: keep and harden, lift and shift, re-platform onto a supported base, or re-build where the old logic is small and clear. In every path the data is migrated with checksums and sign-offs, and the old and new run side by side until the operator cuts over on a date they choose. The old logic is preserved as a written and testable asset, not lost to memory.

Data Pipeline Engineering

Begin intake

Good decisions depend on information arriving clean, on time and in a known shape. Data pipeline engineering builds the permanent routes for that arrival. We design the sources to be extracted on schedule, the transformations to be readable and repeatable, and the destination stores to be governed with clear owners. Every upload is logged; every row that fails validation is quarantined to a file rather than silently dropped. When a pipe breaks, the alert names the job, the source and the last good run, so an engineer or a business owner can see the state in seconds. We test pipelines against realistic volumes before they carry live data. The service gives the company a trustworthy data floor beneath its reports, its automation and its daily operations, so the numbers on the board can finally be believed.

IT Service Management Platforms

Begin intake

Once systems are bound into a well-run estate, the business still needs the machinery of daily care. IT service management platforms give that machinery a home. We stand up an operating platform where incidents, service requests, changes and assets each have their own ledger, their own queues and their own owners. Requesters file a request and watch it move; engineers receive work in order of urgency and priority; changes pass through an agreed approval so nobody alters the live estate in the dark. When a problem strikes twice we turn the incidents into a known error with a written fix, so the same healing is not relearned each morning. The platform closes the loop that the rest of the practice opens: systems that are designed, bound, and then kept under disciplined care.

How each of these ledgers is delivered

Every service above follows the same bound method, which is why we can truthfully call this one practice rather than six scattered trades. Work starts at the intake counter where an operator files a card describing the trouble or the ambition. We reply inside two working days. If the engagement fits a posted ledger we agree a fixed scope sheet naming the owners, the measures and the deliverables. If it sits outside our posted work we say so and will name another office rather than pretend.

Through delivery the office posts progress to build sheets, keeps a dated margin of decisions and tests, and never lets a promise live only in a conversation. When the deliverable is accepted we close the binder, hand over documentation in full and leave the operator with a record another engineer can follow. That archive is the constant that turns a one-off consulting job into a standing, trustworthy service practice.
