Challenges

FinTech Challenges

  • 01

    Fraud at real-time speed

    Instant payments leave seconds, not days, to catch mule accounts, account takeovers and synthetic identities.

  • 02

    Regulation that keeps moving

    RBI digital lending rules, KYC norms, data localisation and audit expectations change faster than legacy stacks can.

  • 03

    Reconciliation pain

    Payments across UPI, cards, wallets and banks settle on different cycles, and finance teams match them by hand.

  • 04

    Legacy core systems

    Batch-based cores and closed vendor platforms slow down every new product launch.

Use Cases

FinTech Use Cases

Typical scenarios we design for: problem, solution, result.

NBFC digital lending journey

01
Scenario
Loan files take days because statements, bureau reports and signatures are collected manually.
What we build
An end-to-end lending flow: Account Aggregator statements, bureau pull, rules-based underwriting, e-sign and e-NACH.
Result
Decisions in minutes with a complete audit trail for RBI reviews.
  • Account Aggregator
  • e-Sign
  • e-NACH
  • Java

Merchant payments & reconciliation

02
Scenario
Settlements from UPI, cards and wallets arrive on different cycles and finance matches them in spreadsheets.
What we build
UPI QR and intent payments with a ledger that reconciles every settlement automatically and flags mismatches.
Result
Same-day reconciliation instead of month-end firefighting.
  • UPI
  • Ledger
  • Kafka
  • PostgreSQL

Real-time fraud monitoring

03
Scenario
A payments app sees rising account-takeover and mule-account fraud, caught only after customer complaints.
What we build
Device, behaviour and velocity signals scored in real time, with step-up authentication and an analyst case queue.
Result
Suspicious payments held before money leaves the platform.
  • Python
  • ML models
  • Redis
  • SIEM

Co-operative bank goes mobile

04
Scenario
Customers queue at branches because the core banking system has no modern channels.
What we build
A secure API layer over the core system, plus mobile and internet banking with UPI and biometric login.
Result
Everyday banking moved from the branch to the phone.
  • API gateway
  • Flutter
  • UPI
  • HSM
New Tech Experiences

Emerging Tech In FinTech

AI, IoT and automation applied to this sector.

02 / New

Instant underwriting with consented data

Account Aggregator bank statements and GST data feed credit models that decide in minutes instead of days.

03 / New

Conversational banking

Balance checks, payments, EMI reminders and support on WhatsApp and voice, with secure handoff to the app.

How We Deliver

FinTech Delivery Process

The same research-first process we use on every financial services & fintech project.

  1. 01

    Week 1–2

    Domain & Compliance Discovery

    We map your workflows, users and the regulations that apply, before a line of code is written.

    Outcome: Requirements, compliance checklist and integration map.

  2. 02

    Week 2–4

    Architecture & Integrations

    We design data models, security controls and the integrations with the systems you already run.

    Outcome: Architecture, API contracts and a clickable prototype.

  3. 03

    Sprints

    Build In Increments

    Working software every two weeks, reviewed with your team and real users.

    Outcome: Releases you can test, not status reports.

  4. 04

    Before launch

    Security & Compliance Validation

    Penetration testing, access reviews, audit logs and documentation for your compliance team.

    Outcome: Evidence that the system is safe to go live.

  5. 05

    Ongoing

    Launch, Scale & Support

    Staged rollout, monitoring and SLA-based support as usage grows.

    Outcome: A platform that keeps improving after launch.

Yes. We integrate UPI intent, collect, QR and AutoPay mandates through payment gateways or partner banks, with webhooks, retries and reconciliation built in.

Yes. We integrate with Account Aggregators as a Financial Information User, so customers can share bank statements with consent and your credit models can use them within minutes.

We tokenise card data to reduce PCI DSS scope, encrypt data in transit and at rest, keep audit logs for every sensitive action, and design flows around RBI guidelines from the start.

Yes. Nexgenex Labs is based in Raipur, Chhattisgarh, and builds for businesses across India and worldwide, with remote delivery, overlapping working hours and on-site workshops where needed.
