Senior Backend Architect for Fintech, Payments, System Design, and AI integrations built to scale reliably.

I am a senior backend engineer and system architect with 8+ years of experience building scalable products in fintech, payments, commerce, and platform engineering. My work has focused on designing backend systems that are reliable under growth, easier to integrate, and practical for engineering teams to implement.

I have helped build systems serving 50M+ users and designed core services across identity, checkout, payments, reconciliation, communication systems, partner onboarding, and developer workflows. A major part of my experience is in payments and fintech integrations, where I designed plug-and-play architecture for banks and payment gateways instead of repeating custom implementation for every new partner.

That system now supports 15+ banks in India, 5 banks outside India, and 3 payment gateways including Stripe, Braintree, and SBIePay. By moving integrations to a reusable, config-driven approach, partner onboarding time was reduced significantly and delivery became easier to scale across teams.

I also have hands-on experience with system design for microservices, API contracts, sync and async flows, retries, webhooks, reconciliation, CI/CD, and multi-region infrastructure readiness. My core stack includes Java, Spring Boot, Kafka, Redis, Vault, Docker, and Kubernetes.

Clients usually work with me when they need one of three things: a strong backend architecture before implementation starts, a specialist for payment or partner integration problems, or a senior engineer who can turn a complex business workflow into a practical technical design and execution plan.

I prefer clear scope, strong documentation, and direct communication. My goal is to reduce ambiguity, reduce rework, and help teams move faster with cleaner technical decisions.

Work Terms

I work best with clearly defined project goals, timelines, and expected deliverables. I can support fixed-scope consulting, architecture reviews, system design, and implementation guidance for backend, payments, fintech integrations, and partner onboarding.

Preferred way of working:
1. Initial discussion to understand the business problem, current system, and expected outcome.
2. Scope alignment with clear deliverables, timeline, and pricing.
3. Execution through structured updates, written notes, and documented recommendations.
4. Final handover with implementation guidance or next-step plan.

Communication style:
- Clear, direct, and async-first communication
- Written documentation preferred for requirements and decisions
- Calls can be scheduled when needed for discovery, walkthroughs, or handover

Availability:
- Available for remote consulting and project-based work
- Comfortable working with overlapping hours across India, Middle East, Europe, and UK-friendly time zones
- Regular updates can be shared during active engagements

Payment and scope:
- Prefer milestone-based or clearly scoped fixed-price work for defined deliverables
- Hourly work is possible for advisory, review, or ongoing engineering guidance
- Any scope expansion should be agreed before execution

Best fit:
- Founders, CTOs, and product teams who need senior technical ownership without hiring a full-time architect immediately
- Teams that want less ambiguity, faster decision-making, and practical architecture output
