CASE STUDY · ENERGY TRADINGIGX: Architecture for an In-House Spot and Auction Exchange

We designed and delivered the exchange portal and trading workstation so Indian Gas Exchange could run Spot and Auction flows on owned infrastructure instead of a third-party exchange dependency.

The platform handled a published daily trading volume of 1.6 lakh MMBTU with a zero-downtime migration from the prior system.

Architecture Decisions That Survive the Build

Slide-only reviews fade after kickoff. Our software architecture consulting turns options into ADRs, backlog criteria, and a thin slice that proves the design.

Options with trade-offs - You see what you gain and what you give up before the SOW locks a single path.
ADRs that feed delivery - Decisions land as acceptance criteria your engineers can execute in your tools.
Prove before you scale - A pilot slice tests the risky seams - integration, data, or cutover - first.

Why Choose BigOhTech for Software Architecture Consulting

Architecture work fails when it never reaches the backlog. Here is how we keep software architecture consulting tied to delivery and risk you can measure.

Icon representing Pilot before the long advisory SOW

Pilot before the long advisory SOW

You pick one decision - target pattern, integration seam, or cutover readiness - and we prove it in a 40-hour free pilot. You expand only when the ADR pack earns trust.

Icon representing Architects who stay through the first slices

Architects who stay through the first slices

Design and delivery stay connected so trade-offs do not get rewritten silently in sprint chaos. You get a named delivery lead in your tools.

Icon representing Custom software architecture design you can build

Custom software architecture design you can build

We write component maps and interface contracts that squads can implement. The design is not a deck that lives in a shared drive forever.

Icon representing Process and security posture

Process and security posture

Consulting and follow-on build run under CMMI Level 3 appraised and ISO 27001 certified practices. Access, logging, and change habits belong in the design early.

Icon representing Path from design to operate

Path from design to operate

When the architecture ships, you have a handoff into build and a route to ongoing support. Decisions do not end at the blueprint review.

Our Software Architecture Consulting Process

Each step ends with a result you can score - constraints, findings, ADRs, or a proven slice - so consulting does not drift into endless workshops.

01

Frame outcomes and constraints

We lock the business outcome, non-negotiables, and the one risk the first decision must reduce. Result: Written problem frame and success criteria sponsors can approve.

02

Assess current-state architecture

We map systems, debt, integration seams, and security gaps that block change. Result: Findings pack with prioritized risks - not a vague health score.

03

Design target-state options

We draft two or more viable structures with explicit trade-offs. Result: Option set your architects can debate with evidence.

04

Decide with ADRs and trade-offs

We record the chosen path, rejected alternatives, and consequences. Result: ADRs that become backlog acceptance criteria.

05

Prove with a thin vertical slice

We test the risky seam - data, integration, or cutover - before full build. Result: Expand/stop evidence from a scoped pilot slice.

06

Hand off to build and operate

We transfer run guidance into delivery and, when needed, ongoing support via IT Support and Maintenance. Result: Clear ownership path after the blueprint.

Choose the Right Software Architecture Consulting Model

Pricing stays Custom because system count, compliance, and integration depth differ. What stays fixed: quality meaning, time-to-start, and a low-risk pilot path. Senior architects who write decisions your teams can build - not junior-only research dumps. A scoped 40-hour free pilot can start after a short discovery call.

Industry InsightsSoftware Architecture Consulting That Cuts Rework Before Build Spend Peaks

We design target states and ADRs that your delivery teams can execute - including security, integration, and operate constraints from day one. Still shipping features while the target architecture stays undecided?

Industry architecture guides still stress that late structural change costs more than early trade-off work - we force option sets and ADRs before code volume explodes.
Buyer planning literature often budgets ongoing maintenance after build; we connect architecture handoff to a real IT Support and Maintenance path so operate ownership is planned.

Frequently Asked Questions (FAQs)

Who owns IP and architecture artifacts?

Your IP, repos, and ADRs stay yours under the MSA and SOW. We work under NDA for architecture and data discussions.


How is this different from hiring a freelance architect?

You get a multidisciplinary partner that can prove decisions with a pilot, feed ADRs into build, and back the work with certified delivery habits - not a single contractor who disappears after the deck.


Why choose BigOhTech for software architecture consulting?

You get pilot-first ADR packs, architecture that feeds the backlog, and a custom agency path into build - not slideware that dies after kickoff. We deliver under CMMI Level 3 appraised and ISO 27001 certified process.


How long until a first architecture decision pack is ready?

A scoped pilot can start after a short discovery call once the decision and constraints are clear. Broader programs take longer when system and partner counts are high.


How do you handle security and compliance in architecture work?

Access, logging, and change evidence are designed into the target state early. Delivery posture aligns with CMMI Level 3 appraised and ISO 27001 certified practices.


What does Custom software architecture design include?

It includes target-state options, component and interface maps, explicit trade-offs, and ADRs your teams can implement. It is design for build - not a style catalog alone.


How is software architecture consulting priced?

Pricing is Custom because system count, compliance, and integration depth differ. We share quality meaning, time-to-start, and a model (pilot, program, or embedded pod) before you commit.


Do you only consult, or do you also build?

We consult and can partner into delivery through Custom Software Development when you want one team from ADR to ship. Architecture ownership stays explicit either way.


Can you modernize architecture without a big-bang rewrite?

Yes. We prefer strangler and parallel-run paths with readiness gates per domain. Pilots still prove the risky seam before wide cutovers.


How does the 40-hour free pilot work for architecture consulting?

We pick one architecture decision and produce an ADR pack plus a thin proof slice inside about 40 free hours. You decide whether to expand without a long SOW first.


What is in scope for Software architecture consulting services?

Typical scope covers strategy and roadmapping, architecture review, custom software architecture design, modernization paths, data/integration architecture, and POC feasibility. First pilots usually own one decision such as target pattern, integration seam, or cutover readiness.


What maintenance and support plan do you offer after architecture ships into production?

We hand off operate guidance and can continue with monitoring, release support, and incident response. See our IT Support and Maintenance service for ongoing ownership options.
