Technical Architecture Lifecycle

Our Technical Engineering Flow

Step-by-step showcase explaining how data propagates securely through our custom software frameworks.

01

API Inflow

Receive transaction requests through secure, low-latency edge proxy endpoints.

02

Serializable Lock

Verify account balances with serializable transaction locks to prevent concurrency leaks.

03

AML Screening

Screen beneficiary details against active compliance datasets in real-time.

04

Ledger Commit

Commit balances to immutable double-entry databases with secure keys.

Challenges We Solve

How we tackle complex enterprise vulnerabilities with high-security, custom architectural resolutions.

Data Localization Mandates

The Pain Point:

Storing financial transactions outside local borders, violating RBI rules or federal banking parameters.

Our Resolution:

We build secure multi-region databases enforcing geographic localization, ensuring domestic transactions stay within local borders.

Payment Credential Safety

The Pain Point:

Securing credit card queries during global checkouts without storing raw financial details on internal systems.

Our Resolution:

We design isolated payment gateways utilizing hardware-level tokenization, removing raw card values from local scopes.

Anti-Fraud Verification Lag

The Pain Point:

Slow verification speeds in payment networks leading to fraud or high transaction failure rates.

Our Resolution:

We construct real-time event-driven transaction scoring APIs that screen balances against local sanction lists in milliseconds.

Key Solutions

Frequently Asked Questions

Clear, honest answers about our remote operations, workflows, tech stack, and partnership structures.

We are a remote software studio based in Uttarakhand, India. We partner with product teams and enterprises globally to build reliable web applications, robust databases, and custom business tools.
We work asynchronously and adapt to your team's primary time zones (including US, UK, and European hours). We communicate through Slack, GitHub, and email, ensuring daily updates and weekly progress reviews.
We build primarily with Next.js, React, Node.js, TypeScript, PostgreSQL, and Tailwind CSS. We also design custom PostGIS integrations for mapping datasets and secure FHIR/HL7 database feeds for healthcare systems.
We keep pricing straightforward and transparent. We offer fixed-scope pricing for well-defined projects, and monthly/weekly developer retention models for ongoing product engineering and maintenance.
Yes, Totally Optimised Solutions is a registered Indian MSME under the Ministry of Micro, Small and Medium Enterprises, Government of India.
All intellectual property, repositories, and credentials belong entirely to you from day one. All code is delivered under standard commercial-use licenses (typically MIT or custom proprietary agreements) upon project completion.
Yes. We offer dedicated maintenance packages covering server monitoring, security patches, library updates, and quick bug resolution to keep your software running flawlessly post-launch.
We sign standard mutual NDAs before any code or database schema is shared. Our development pipelines enforce strict environment variable segregation, encrypted database-at-rest policies, and secure API keys handling.
Yes, we frequently build custom integration layers, REST/gRPC API adapters, and secure database sync systems to connect modern Next.js/React frontends with legacy ERPs or local databases.
Typically within 1 to 2 weeks. Once we agree on the scope or developer capacity, we spin up dedicated repositories, define the first milestone, and begin writing code immediately.
