Scoped contract work · one accountable engineer
A small studio for bounded technical delivery.
NextEleven is an owner-operated DFW software studio led by Sean McDonnell. It works with organizations that need a difficult failure investigated, a backend or integration implemented, a retrieval workflow made usable, an operational system built, or a modern web presence delivered on a foundation that can expand over time. Clients work directly with the owner responsible for scope, implementation, verification, and handoff.

Confidential client delivery
Written scope before implementation
Tests + documentation in the handoff
01Available product
Free pings. Private automation.
AK47 Founding Freeze is experimental, named-license software for selected Kalshi Bitcoin event-contract workflows. It runs on infrastructure and accounts controlled by the licensed owner, begins stopped and in non-ordering test mode, and includes a documented handoff. It is not financial advice, a managed account, custody, or a promise of results.
Limited personal-use release · availability confirmed in writing
AK47 Founding Freeze
The free public Telegram posts remain available. A completed purchase can include private automation that runs while the owner’s server, credentials, network, exchange access, and configured services remain available. Exact capabilities, price, license, and support are stated in the written offer.
- Current price confirmed in writing
- Personal-use license terms control
Sales boundary
Code and information—not an outcome
No checkout, no wallet assumptions, and no request for credentials. Prospective buyers review the costs, requirements, risk, license, support, and limitations first. Sean then determines fit and sends a written offer.
- No financial advice or managed account
- No profit, win-rate, activity, or uptime promise
02Good-fit engagements
Specific problems with a finish line
The best engagement has an owner, a current failure or requirement, access to the relevant evidence, and a concrete definition of done.
Troubleshooting
Reproduce and isolate a difficult failure
Logs, API behavior, cross-platform failures, CI, regressions, environment differences, and a written root-cause record.
Implementation
Build a bounded backend or workflow
Python/FastAPI, TypeScript/Next.js, REST integrations, PostgreSQL, Redis, operator interfaces, and explicit human-review paths.
Retrieval & applied AI
Make source-grounded workflows usable
Ingestion, hybrid retrieval, reranking, citations, tool calling, evaluation cases, escalation, and honest failure behavior.
Handoff
Finish the unglamorous closing work
Automated checks, runbooks, limitations, architecture notes, demonstrations, and a next-owner handoff another person can follow.
03Evidence
Inspect the work before trusting the pitch
Public repositories support the engineering claims. Private-client contract work is described through architecture, verified checks, and anonymized workflow details—not client names or invented outcomes.
Private-client delivery · confidential
Multi-location dealership workflow
Python, FastAPI, PostgreSQL/pgvector, Redis, Next.js, search, inventory, orders, invoices, dashboards, and human-reviewed external actions.
- Automated backend and API verification
- Anonymized workflow brief available publicly
Public engineering proof
Rust developer tooling
Harness is a proprietary public proof of concept with user-selected provider/model routing, compatible custom endpoints, sandboxed tools, MCP, sessions, parallel workers, security notes, and local interfaces.
- Documented automated tests
- Cross-platform continuous integration
Client web-presence delivery
JP Transmission
NextEleven designed and implemented JP Transmission’s bilingual web presence with distinct buyer and seller journeys, responsive layouts, a configured inquiry path, and browser-based Ask JP guidance using approved site information. Inventory, ecommerce, and checkout remain separately scoped future capabilities.
- English and Spanish visitor experience
- Future commerce is scoped separately
04Process
From ambiguity to an inspectable handoff
The schedule follows the verified scope, dependencies, and acceptance conditions.
- 01
Establish fit
Clarify the owner, present failure or requirement, constraints, available evidence, and whether Sean is the right person to help.
- 02
Write the boundary
Agree on deliverables, exclusions, verification, access, communication, cost, and the concrete condition that ends the engagement.
- 03
Deliver narrow increments
Show working evidence early, state blocked assumptions, and keep unrelated feature ideas out of the active scope.
- 04
Verify and hand off
Provide the agreed checks, source or artifacts, documentation, known limitations, and a clear record of what remains.
05Boundaries
What NextEleven does not pretend to be
- Owner-operated.Sean McDonnell is the accountable owner and primary builder. Any outside contributor is disclosed before involvement.
- No guaranteed outcomes.NextEleven does not guarantee investment returns, revenue, cost reduction, adoption, rankings, lead volume, uptime, or other business outcomes.
- Implementation is not adoption.Completed implementation, demonstrations, and tests are reported separately from deployment, client acceptance, production use, and business results.
- Written commercial terms.Scope, fees, schedule, assumptions, ownership, support, acceptance, and cancellation terms are recorded in the signed agreement.
- No client identity used as borrowed credibility.Confidential systems remain anonymized unless a client explicitly authorizes disclosure.
