Everything you need to get to the shelf.


Four practice areas, one engineer. I run only the Forge Method phases your project needs, and I tell you up front what it will cost.

// SYS_PLAN

Systems Architecture & Planning

I define the whole product before anyone builds a piece of it: requirements decomposition (PRD/FRD), risk analysis (FMEA), and technical roadmapping, so you know the budget before you buy tooling.

Systems ArchitecturePRD / FRD / SRD WritingDFMEA / SFMEATechnical RoadmappingBudgeting & Cost Modeling
// DESIGN_PROTO

Electromechanical Design & Prototyping

SolidWorks CAD, PCB integration, and rapid 3D-printed iterations. Your mechanics and electronics are designed together from day one, so they actually fit when manufactured.

Mechanical & Electromechanical DesignRapid Prototyping & DFM
// VV_DFM

Verification, Validation & DFM

Test plans and protocols that prove your product works. Once it’s validated, I prepare the engineering drawings and supplier quotes that make your design mass-manufacturable.

// LEAD_MENTOR

Leadership & Mentoring

I lead cross-functional teams of teams, facilitate design reviews, and mentor engineers and students through hands-on technical coaching.

Capped at $55 / hr with no-guess costing: every job is quoted before it starts, and there’s no retainer.

Process

No retainers. No guesses.


Every project runs on the Forge Method: six phases from discovery to handoff. I scope only the phases your project needs and quote the hours and cost before work starts, so you never pay to figure out the plan.

Phase 0 · Reading the OrderDiscovery & Definition
Phase 1 · Striking ConceptsConcept & Feasibility
Phase 2 · Shaping at the AnvilDesign & Verification
Phase 3 · Forging in MetalMaterial Prototype & Validation
Phase 4 · Tempering for ProductionProduction & Launch
Phase 5 · Banking the CoalsHandoff & Lifecycle
Past Work

Real quotes. Real products.


I quote the hours and the cost before work starts. These are proposals clients accepted, and work that got done. Each engagement runs only the Forge Method phases (0–5) the project actually needs.

About

Led by Sean Neal.


Sean Neal, founder and lead engineer of The Dimensional Forge

I’m Sean Neal, a Senior Systems Engineer and product development consultant in Indianapolis. I analyzed rocket-engine test data at NASA Marshall Space Flight Center, interned twice at Tesla, did medical device R&D at SonaCare, and have spent eight years delivering connected hardware at Allegion, where I carried a WiFi smart-lock family from concept to retail shelves.

I started The Dimensional Forge so that experience could work for inventors, startups and small businesses who need senior engineering without a big firm’s overhead: from first concept through architecture, prototyping, validation and manufacturing readiness. When something goes wrong on a project I own it, say so plainly, and fix it.

Community & Leadership

Outside my day job I mentor, teach and organize. My leadership philosophy is simple: people first, systems second, ego last.

FIRST Robotics · Team 6956

Co-Lead Mentor · since 2019

I co-lead about 20 high school students through a six-week design, build and compete season every year, against a deadline that doesn’t move. I coach design, fabrication and project execution under pressure, and how to recover when something breaks.

Award · May 2021 FIRST Indiana District Chairman’s Team Award FIRST’s most prestigious award, for the team that best models its mission for other teams to follow.

Minority Engineering Program of Indianapolis

Co-Leader & Lecturer · since 2019

In 2019 I rebuilt MEPI’s 8th-grade engineering curriculum around Arduino, robotics and hands-on systems thinking, replacing an outdated program. I’ve designed and taught it every year since, to open a path into engineering for students who are underrepresented in it.

Allegion Pride Alliance

Founder · since 2022

I founded Allegion’s Indianapolis LGBTQIA+ employee resource group: I set its strategic agenda, recruited and lead a team of six volunteers, and serve as corporate liaison and Inclusion & Diversity Chair. We ran Allegion’s presence at Indy Pride 2024.

Supportive Husband

Behind the scenes

My wife, Eleanor Hernly, LMHC, is an incredible therapist in Indianapolis. I’m proud to help out behind the scenes with operations, support and spreading the word about Eleanor’s practice, which offers in-person and online sessions with a collaborative approach that blends mindfulness, ACT and DBT.
