I am an experienced, honest and dedicated web developer. I have worked on projects from scratch as well as doing my part in the customization of large scale projects. I have the experience of working in team as well as individually. I have always got excellent feedback regarding the work I have done on projects so there will be no compromise on quality of work from me.

I build regulatory reporting and compliance automation systems for fintech companies operating under EU banking regulations. My background combines backend engineering (Node.js, TypeScript, AWS) with hands-on experience implementing xBRL, DPM taxonomy validation, and EBA reporting frameworks (DORA, CMRS, IFR).
Most fintech teams either build compliance tooling in-house without specialized engineering support, or rely on expensive legacy vendors. I help teams build maintainable, automated reporting pipelines that reduce manual effort and lower the risk of regulatory errors.
What I've built:
An xBRL Conversion & Reporting Engine covering EBA modules, automating financial validation and reducing manual reporting effort by 90%
A DPM taxonomy and datapoint verification engine using graph traversal (DFS) to validate hierarchical regulatory dependencies
Backend systems supporting 1M+ users in a live fintech production environment, with 45% improved API response times

I build signal-driven outbound systems using Clay as the core engine, designed for cold email or multi-channel outreach.
The goal isnโt more data.
Itโs clean targeting, fast execution, and messaging that converts without wasting credits or over-engineering the setup.
Here's how I can help you:
1) Signal-Based Lead Sourcing
I build lead lists from scratch using real outbound signals:
- Scraping jobs, websites, and directories via Apify
- Identifying recently active or high-intent accounts
- Persona-based targeting (role + context, not titles alone)
- Early company and role-level qualification
2) Data Collection, Enrichment & Verification
I collect and enrich data using Clay plus external tools to maximize accuracy:
- Importing data via APIs using HTTP requests and JSON
- Mapping API responses into clean, usable Clay columns
- Enriching only ICP-relevant data points
- Email/phone verification using email + phone waterfall logic
3) Lead Scoring & Outbound Qualification
I design clear, explainable scoring logic inside Clay to support outbound prioritization:
- Persona fit
- Company relevance
- Signal strength
- Data reliability
This ensures your team knows whom to contact first, without guessing.
4) Cost-Efficient, Scalable Clay Systems
I built Clay tables that are:
- Credit-efficient
- Modular and reusable across campaigns
- Easy to scale across channels
- Structured for real outbound execution
5) Data-Driven Messaging for Multi-Channel Outreach
Once the data is right, messaging becomes simpler and more effective.
- Turn data points into real personalization angles
- Align messaging with the correct ICP persona
- Support cold email, LinkedIn, and multi-channel outreach
- Avoid robotic, token-based personalization
A big part of how I work comes from being inside the Clay Bootcamp environment, where the focus is hands-on execution, building systems that are cost-effective, fast to deploy, and practical at scale.
If your outbound setup feels slow, expensive, or hard to scale, thatโs usually a system design issue.
Happy to take a look and help you fix it.
See you on the other side!
