By day I build cross-border payments & FX infrastructure at Aspire. On the side I'm building Nideknil, an AI hiring platform that ranks every candidate for a role using vector retrieval, reranking and LLM evaluation.

Who I Am
Engineer. Problem Solver.
Engineer. Problem Solver.
AI Enthusiast.
I'm a Software Engineer with deep expertise in distributed systems, microservices, and fintech backend architecture. Currently at Aspire, building cross-border payments and FX infrastructure across SG, HK, AU, US and SEA. Previously at WebEngage and Groww.
I graduated from Indian Institute of Information Technology Nagpur in Computer Science, and am passionate about competitive programming — 4★ on CodeChef.
Outside work I'm building Nideknil ("LinkedIn" spelled backwards), an AI hiring platform I designed and shipped end to end. It covers a candidate-ranking funnel, a merit-ranked referral marketplace, and AI-fluency scoring that uses Claude Code and MCP.

Software Engineer 2Jan 2025 – Present
Aspire · Bangalore
- Wallex SEA multi-region launch: built IDR/PHP/MYR/VND collections, FX conversion and local payouts end to end for HK, AU and US clients in Java and Golang. Includes per-region credential isolation, idempotent Kafka webhook processing and automatic rollback of failed legs. Launched in 3 new regions with FX into 13 currencies.
- HK migration engine: a resumable, step-tracked Java workflow that moved 1,800+ clients from CC-SG to CC-HK. It automates balance transfers, account creation, recipient migration and ledger sync, with safe re-runs and retries that respect rate limits. Cut manual ops by 60%.
- Concurrency-safe transaction limits: configurable outbound limits for POB-unverified businesses across every transfer flow (single, bulk, scheduled, bill and claim). Distributed locking prevents concurrent overspend, with maker-checker controls and rollback on failure. Boosted new-business activation by 42%.
- Multi-rail payout service: DBS-SG ACT, DBS-HK TT and CC-HK transfer flows in Golang with provider-level error handling and retries. Reduced cross-border FX transfer failures by ~30%.
- Huifu CNY payment rail: a new cross-border CNY corridor built end to end, covering recipient creation, transfer dispatch, fee calculation and Unified Social Credit Code validation. Opened China payouts for HK clients.
- Recipient platform at scale: rebuilt recipient create/update/delete/migrate flows with a zero-downtime MySQL migration, query optimization and caching on
GET /v1/counterparties. Added fallback provider routing for when Payout Hub is disabled. Cut p95 latency by ~70% and scaled to 30,000+ businesses. - Observability & reliability: integrated Sentry, OpenTelemetry and Datadog across Aspire Hub, and built AWS S3 statement ingestion with exponential-backoff retries and Slack alerts. Cut incident MTTR by ~50%.

What I'm Building
Nideknil: LinkedIn, flipped.
An AI hiring platform I designed, built and shipped solo. Recruiters don't hunt through profiles; AI ranks the whole candidate base for any role.
Nideknil
Founder & Engineer · Jun 2026 – Present
Screening every applicant with an LLM is slow and expensive, so Nideknil treats the LLM as the scarce resource. Cheap stages cut the pool down first, and only the top handful of candidates reach deep AI evaluation. Every score comes back explainable, factor by factor.

🎯 Candidate Ranking Funnel
Resumes are parsed and embedded at upload time, so a "rank now" request scales with top-k, not corpus size. Runs async on Celery + Redis, with SHA-256 resume dedup and a Redis cache for LLM responses.
🤝 Merit-Ranked Referrals
Verified employees open referral posts. Applicants are AI-ranked into a live top pool plus a waitlist, and referrals happen within a time-boxed window. No cold DMs, no popularity contest.
⚡ AI-Fluency Scoring
Take-home assignments are delivered through Claude Code MCP servers. Candidates submit session transcripts with a CLI that redacts secrets locally, and a Claude judge scores them on a weighted 8-category rubric.
📈 Nideknil Pulse
A B2B product that measures a whole engineering team's AI fluency, built on the same transcript-scoring engine.
🏊 Pools, Displacement & Reserve
Each job has a limited acceptance pool. Stronger applicants displace weaker ones, displaced candidates move to a reserve pool, and every status change triggers an email.
✉️ Outreach Agents
LLM agents that turn a hiring post into a personalized pitch or a full cold-email application, with multi-provider fallback (OpenAI, Groq, Gemini).
