localhost:5001 → production. 200 OK.
From localhost to live — no drama.
A senior .NET architect with 9+ years shipping to production, backed by a hand-picked offshore bench. Re-architected a live SaaS platform in 15 days without downtime. Built CI/CD for a 50-engineer team. Kept production at 200 OK through all of it. Senior ownership at offshore rates — no juniors on your codebase, no account manager in the thread, no faceless agency layer.
What :5001 Brings.
A senior engineering lead plus a vetted offshore bench. Systems built to outlast the teams that commission them.
Backend Systems
End to End
From RESTful API design and database schema to Docker containers, CI/CD pipelines, and server clustering — a decade of owning the full backend delivery cycle. No writing services and handing them off. No "devops is out of scope".
Q2–Q3 2026
Limited capacity per quarter. Senior-led engagements only — no juniors on your codebase.
The Right Pattern
for the Problem
CQRS with MediatR, Clean/Onion Architecture, N-Layer, Repository Pattern — and knowing when a well-structured monolith beats a premature microservices decomposition. Patterns chosen for the constraint, not the CV.
Shipped, Containerised
and Running
Custom CI/CD pipelines, Docker containerisation, Kubernetes orchestration, and server cluster management — the deployment side gets the same engineering rigour as the code itself.
Across SaaS, FinTech, and Enterprise — the systems are still in production.
Real systems.
Real constraints.
A Field Management SaaS was collecting real customer feedback daily — which meant daily new requirements hitting a codebase that couldn't handle them. Merge conflicts were constant. Deployments were scary. Team morale was breaking down. Features were piling up with no clean way to isolate changes.
Full re-architecture from scratch while the platform stayed live. Moved to strict Clean Architecture to isolate business logic. Implemented CQRS with separate read/write paths so reporting never slowed down data entry. Introduced Unit of Work and Repository patterns. Split into multiple databases where service boundaries demanded it. Pushed CI/CD pipelines to make branching and deployment predictable.
A dev team of 40–50 engineers across multiple projects was still deploying via FTP and manual file transfers. Managing separate Staging, QA, and Client Demo environments was a full-time job. One wrong upload could overwrite another developer's work. The process wasn't scaling.
A centralised GitLab pipeline built from scratch — connected to custom Linux servers configured specifically for automated deployments. Runners set up to handle concurrent projects without bottlenecks. Distinct Staging, QA, Demo, and Live environments for every project. Automated database migrations and application configuration on every push. Network and security handled end-to-end.
One stack. Deeply known.
Built for specific teams.
Not every brief is a fit.
Teams that want senior ownership at offshore economics — without the agency tax.
Some engagements are better served by someone else. No hard feelings.
How engagements actually run.
No account managers. No ticket theatre. No juniors practising on your codebase. A senior .NET lead drives every engagement end-to-end — and a vetted offshore bench scales in only when the scope demands it.
Senior lead, no juniors on your codebase
Every engagement is driven by a senior .NET lead with 9+ years in production. When bandwidth demands more hands, a small vetted bench of senior engineers scales in — matched to the work, never juniors, never outsourced discovery.
Your repo. Your infra. Your IP.
Work happens inside your GitHub / GitLab / Azure DevOps, on your cloud, through your pipelines. No proprietary tooling, no vendor lock-in, no "we'll hand it over at the end". IP assignment is standard and signed upfront.
NDA signed before the repo clone
A mutual NDA is signed before any codebase walkthrough or architecture review. Standard confidentiality and IP terms available — or send yours, we'll sign. No code review without it.
8+ hours daily overlap · US / EU hours
Standups, PR reviews, and incident response happen in your working window — not "we'll pick it up tomorrow". Daily overlap with US Eastern, UK, and Central European hours is built into the engagement.
Hourly with itemised invoices — or fixed-scope
Hourly retainer tracked in Harvest / Toggl, with itemised weekly invoices — every hour shows the ticket, branch, and PR it went to. Fixed-scope with milestone billing for well-defined builds. Invoicing via Stripe or Wise in USD / GBP / EUR.
Direct line to the lead · weekly written update
Slack, Teams, email, Linear — whatever your team already uses. No PM layer. No account manager. No salesperson in the thread. A written status goes out every Friday in your timezone — what shipped, what's blocked, what's next.
From reply to running.
The first 48 hours, mapped.
No Calendly maze. No SDR triage. No "we'll route you to the right rep". One email, one senior reply, one call, one SOW — and the first PRs land inside week one.
dev@port5001.com. One paragraph on your stack, the constraint, and what needs to move. No form, no deck request, no intake call.
Questions worth
answering first.
Who actually writes the code — the lead, or someone junior?
What about my IP? Do you own any of the code?
Do you work through an MSA and SOW?
How is time tracked and billed for hourly work?
How does the timezone actually work?
Can you onboard through our procurement / vendor system?
What stops this from feeling like every other offshore shop?
What does a typical first engagement look like?
