KYC Platform Backend Engineer (Node.js / TypeScript) – Compliance Systems (USA LLC)

@Herculesz

Hi I can step into your existing KYCgini production system and focus on stabilizing and extending the Node.js + TypeScript backend without rewrites or framework changes. I’ve maintained compliance-grade backends covering KYC onboarding, document verification, risk scoring, and immutable audit logs, where correctness and traceability mattered more than speed of feature churn. I’m comfortable integrating and maintaining sanctions/PEP screening APIs, tightening logging and error handling, and fixing edge cases in live flows while respecting established architecture. I’ve worked with Solana RPC calls and wallet signature verification strictly for identity/compliance contexts (no trading), and I can keep those flows reliable. On the frontend, I can wire and fix API integrations in an existing React dashboard as needed—functional fixes only. I confirm I can commit 4 hours daily at $300/month for 3–6 months, working independently and aligned with US compliance expectations. Timezone: UTC+1, available 14:00–18:00 UTC daily. Thanks, Hercules

Hello Lucky, I’m Abdul, a Software Engineer with 6 years of full-stack experience, specializing in Node.js and TypeScript backend development. I have hands-on knowledge of Solana blockchain, including wallet integration and signature verification, aligning well with your compliance system's tech stack. Regarding backend compliance systems, I have supported an AML/KYC module within an e-commerce platform, ensuring audit-trail integrity and user onboarding flows complied with regulatory standards. One Node.js system I maintained was a payment gateway backend where I optimized error handling, improved risk scoring integration, and stabilized API connections under heavy loads—similar to your requirements. I confirm I can commit 4 hours daily for $300 per month and am comfortable with US compliance practices. I’m in the GMT+3 timezone and available from 10 AM to 2 PM GMT+3 daily. I look forward to contributing to KYCgini by stabilizing and enhancing your backend while ensuring compliance robustness and smooth Solana wallet operations. Thank you.

We've just completed a similar project. I recently maintained and extended a production-ready KYC / AML compliance platform built with Node.js and TypeScript, including audit logging, document verification flows, and integration with sanctions and PEP screening APIs. We will help you stabilize and maintain KYCgini’s backend, ensuring Solana wallet verification works, compliance flows remain robust, and the React dashboard integrates cleanly with minimal frontend adjustments. You won't find someone better aligned with what you're looking for. I understand the need for production-level Node.js/TypeScript maintenance, KYC lifecycle handling, blockchain wallet verification in a compliance context, audit trail integrity, and independent, consistent output under strict US compliance expectations. I'd love to chat about your project! The worst that can happen is you walk away with a free consultation. Regards, Danie.

Hi there, I am a strong fit for this role because I maintain and stabilize existing production backends under strict operational constraints. I have worked on compliance-oriented systems where auditability, data integrity, and controlled changes mattered more than feature velocity. I have 7+ years of experience handling Node.js and TypeScript backends, including JWT auth, REST APIs, audit logging, risk workflows, and third-party compliance API integrations. I have maintained live systems with wallet verification flows, RPC calls, and signature validation, and I follow existing architecture without rewrites. I reduce risk by working incrementally, fixing edge cases with logs and tests, and preserving compliance patterns already in place. I confirm availability for 4 hours daily at $300 per month and can start immediately. Regards Chirag

@mubeenm5026

With my extensive experience in backend engineering, especially in the realm of compliance and blockchain solutions like the one your KYCgini platform presents, I'm confident that I can deliver exceptional work on this project. One notable project that aligns with this undertaking is when I spearheaded the development of a comprehensive AML compliance system for a fintech company - from onboarding to customer document verification, and risk scoring just as KYCgini embraces. Moreover, over the years, my proficiency in working with Node.js and TypeScript has grown exponentially. It also extends to understanding key compliance elements such as audit logging and data integrity - both challenging aspects of any functional financial system. My experience in blockchain technologies specifically Solana RPC is another asset that differentiates me from other candidates. While at it, I also gained meaningful knowledge in maintaining wallet verification flows including signature validation – skills relevant to your system’s needs.

@Ivanor1505

Hi, I understand KYCgini is already live and the priority is stabilizing and extending an existing KYC/AML system under real compliance constraints. Because this is production code, the work centers on careful backend maintenance, edge-case fixes in onboarding and verification, and disciplined audit logging without architectural changes. In practice, I would review current KYC flows, harden error handling and logging, then maintain sanctions screening and Solana wallet verification so identity checks remain reliable. I’ve maintained a production Node.js compliance backend where strict audit trails and incremental fixes prevented regressions during regulatory reviews. Given the fixed scope, steady daily progress is realistic over several months. Do you already have automated tests around KYC flows, or should stabilization start with targeted coverage?

@tobiask5

Hi how Are you? I have ever worked on the similar project back in the day. I have worked on KYC platform for ADXX coin. Let 's discuss further in chat. Thanks Sincerely
