About Shubham
Independent Product Engineer & Systems Architect. Shipped continuous commercial software across 20+ countries since 2017.
I don't build commodity websites. I engineer systems that solve business problems.
I am an independent product engineer and systems architect. Over the past nine years, I have architected and deployed more than 60 commercial software platforms across 20+ countries—ranging from high-volume European fintech CRMs to industrial corrosion inspection engines and multi-tenant B2B SaaS applications.
Founders and companies typically reach out to me when they are at an inflection point:
- They have a verified business idea and cannot afford agency delays or technical debt.
- Their AI-generated prototype (Cursor, Claude) has hit a wall of broken state and database chaos.
- They need high-conviction Fractional CTO leadership to defend their architecture in investor diligence.
In every scenario, I do not just write syntax; I understand the business problem, design the underlying system, and ensure it gets built right.
From First Commercial Deployment to Global Engine
My first commercial deployment went live on February 4, 2017—a custom logistics algorithm for a regional transport operator that replaced an expensive legacy ERP. The project was quoted for four months; I architected and deployed it in four weeks.
That engagement revealed an enduring market reality: The world does not need more programmers who blindly write specifications. It desperately needs product-minded engineers who understand commercial leverage.
In 2020, as client demand expanded into complex multi-tenant platforms, I tested building a traditional agency. I hired project managers, coordinators, and junior developers. The experiment failed my standards: communication velocity plummeted, code quality degraded, and I spent my days managing administrative overhead rather than architecting systems.
So I dismantled it. I rebuilt my practice into what it is today: The Direct Partner Model.
The Delivery Model: Shubham + Specialized Team
How do I deliver entire platforms in 4 to 8 weeks while maintaining single-point accountability?

Engineering Philosophy
Monoliths Over Microservice Sprawl
Most early-stage microservice architectures fail from distributed state complexity and RPC latency. A modular monolith scales into millions in revenue with a fraction of the operational cognitive load.
Database Kernel Row-Level Security
Application-level WHERE tenant_id = x clauses inevitably leak data under fast iteration. I enforce tenancy boundaries at the PostgreSQL kernel via Row-Level Security (RLS).
Deterministic State Around AI Models
LLMs are inherently probabilistic. Production AI systems require deterministic wrappers: Finite State Machines, strict Zod schema validation, and semantic prompt caching.
100% Intellectual Property Handover
I do not hold clients hostage with proprietary lock-in or licensing fees. Every repository, cloud environment, and architectural diagram is 100% owned by the client from day one.
Operating across 20+ countries and global financial hubs.

You own the system.
The code. The infra. The data.
Software should not become valuable enough to matter and then be impossible for the client to own or operate.
Everything I build is 100% client-owned intellectual property from day one. You own the code, the accounts, the infrastructure, and the data. No vendor lock-in.
